If Start() succeeds, the callback is only executed when the setup is
complete (on the stack of RestoreTPL()), rather than on the stack of
InstallMultipleProtocolInterfaces(), when the driver setup may yet be
theoretically incomplete.

If Start() fails, the protocol interface will have been uninstalled
(rolled back) by the time the callback runs (again, on the stack of
RestoreTPL()). Since protocol notification callbacks begin with locating
the protocol interface in question, such attempts to locate will fail
immediately and save some work in the callback.

Laszlo Ersek 92e745505c OvmfPkg: PlatformDxe: add form widgets for video modes
In this patch we populate the form with the two widgets related to video
resolution:
- A read-only string field displaying the preference for the next boot.
- A drop-down list offering choices for changing the setting. This list is
  implemented with dynamically generated IFR opcodes.

(In general, the current preference may be missing, or it may be invalid
for the available video RAM size. The list of possible new settings is
filtered with the video RAM size.)

Because the form now becomes able to receive input, we must also implement
ExtractConfig(). This function tells the HII engine about the state of the
widgets.

For now we set up both widgets with static data only:
- The current preference always says "Unset". The driver code is still
  isolated from the backend (the UEFI variable store).
- The list of possible resolutions offers 800x600 only. We don't
  interrogate the GOP yet.

Laszlo Ersek 5267c89b4d OvmfPkg: PlatformDxe: utility functions for saving / loading configuration
The two functions introduced here allow the saving and loading of platform
configuration to/from the non-volatile variable store.

The PLATFORM_CONFIG structure and the two functions that take it / return
it are generally meant for any DXE or UEFI driver that needs to access
platform configuration. For now we keep this small "library" internal to
PlatformDxe.

The PLATFORM_CONFIG wire format is intended only to grow over time (as
long as the variable GUID remains unchanged). At the introduction of new
fields, new feature flags must be added, and recognized in
PlatformConfigLoad().

Laszlo Ersek de5ae37bb2 OvmfPkg: BDS: remove historic (now defunct) boot mode hack
When PI can distinguish the "full config" boot mode from "assume no
changes", then the following BDS logic is correct:

  if BootMode == BOOT_WITH_FULL_CONFIGURATION:
    //
    // connect all devices
    // create & append each default boot option that's missing
    //
    BdsLibConnectAll
    BdsLibEnumerateAllBootOption
  else if BootMode == BOOT_ASSUMING_NO_CONFIGURATION_CHANGES:
    //
    // just stick with current BootOrder and the Boot#### variables
    // referenced by it
    //

In theory, the first branch is intended to run infrequently, and the
"assume no changes" branch should run most of the time.

However, some platforms can't tell these two boot modes apart. The
following substitute had been introduced:

  //
  // Technically, always assume "full config", but the BootMode HOB is
  // actually meaningless wrt. to "full config" or "assume no changes".
  //
  ASSERT (BootMode == BOOT_WITH_FULL_CONFIGURATION);

  //
  // Key off the existence of BootOrder. Try to prepare an in-memory list
  // of boot options, based on BootOrder and the referenced Boot####
  // variables.
  //
  Status = BdsLibBuildOptionFromVar()

  //
  // If that succeeded, we'll treat it as "assume no changes".  If it
  // failed (*only* if it failed), we'll build default boot options,
  // calling it "full config":
  //
  if EFI_ERROR(Status):
    BdsLibConnectAll()
    BdsLibEnumerateAllBootOption(BootOptionList)

What we have now in OVMF is a mixture of the hack, and the behavior that's
theoretically correct for "full config":
- We assert "full config" -- this is OK.
- We call "connect all" and "enumerate all" deliberately -- this is OK
  too. It matches "full config" which we assert.
- However, we also have the hack in place, which had been meant as an
  alternative.

In order to clean this up, we either need to restore the hack to its
original form (ie. comment out the unconditional calls again), or we ought
to remove the hack altogether.

The unconditional "connect all" + "enumerate all" calls are the correct
approach for OVMF, because we want, in fact, to start with "full config".
The QEMU boot order specification and the set of emulated devices might
change "out of band", which excludes "assume no changes".

In other words, removing the hack corresponds to the "real production"
case that the comment hints at.

Because SetBootOrderFromQemu() may change the BootOrder NvVar, we must
preserve the BdsLibBuildOptionFromVar() function call, in order to
refresh the in-memory list with the new boot priorities.
(The last step of BdsLibEnumerateAllBootOption() is such a call too.)

This driver (from
"MdeModulePkg/Universal/Acpi/BootScriptExecutorDxe/BootScriptExecutorDxe.inf")
is first loaded normally during DXE. When the
EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL is installed by any DXE driver (purely
as a form of notification), the driver reloads itself to reserved memory.

During S3 Resume / PEI, the driver image is executed from there. In order
to access the boot script saved during S3 Suspend, LockBox access is
needed.

The boot script is transferred internal to PiDxeS3BootScriptLib:

Both S3SaveStateDxe and BootScriptExecutorDxe are statically linked
against PiDxeS3BootScriptLib. Whichever is loaded first (during normal
boot, in the DXE phase), allocates the root storage for the script. The
address is then passed between the PiDxeS3BootScriptLib instances living
in the two separate drivers thru the dynamic
PcdS3BootScriptTablePrivateDataPtr PCD.

  BootScriptExecutorDxe

Laszlo Ersek d4ba06dfdc OvmfPkg: S3 Resume: fake LockBox protocol for BootScriptExecutorDxe
BootScriptExecutorDxe, to be pulled in in the next patch, was written with
the SMM implementation of LockBox in mind. That implementation is split in
the following three parts:

- client side (DXE/PEI) library,
- SMM driver producing gEfiLockBoxProtocolGuid,
- driver side (SMM) library.

BootScriptExecutorDxe includes the client side LockBoxLib. So that the
library can communicate with the SMM LockBox driver, BootScriptExecutorDxe
has a Depex on gEfiLockBoxProtocolGuid, normally installed by the SMM
LockBox driver. This is actually not a hard dependency, it just ensures
correct load order between BootScriptExecutorDxe and
MdeModulePkg/Universal/LockBox/SmmLockBox.

The (client side) LockBox library instance in OVMF doesn't depend on a
separate driver that produces gEfiLockBoxProtocolGuid. Nothing  produces
that GUID right now in OVMF. This prevents BootScriptExecutorDxe from
loading.

Install gEfiLockBoxProtocolGuid in our only S3-specific, custom DXE
driver, in order to enable loading of BootScriptExecutorDxe.

Laszlo Ersek 5a217a0649 OvmfPkg: S3 Suspend: save boot script after ACPI context
The trigger to actually save the boot script is the installation of
EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL, to be performed by any DXE driver.
Installation of the protocol also locks down SMM (as its name indicates)
and (in theory) prevents further LockBox access.

We cannot install this protocol before BdsLibBootViaBootOption() is called
(eg. in OVMF's PlatformBdsPolicyBehavior()), because
BdsLibBootViaBootOption() calls EFI_ACPI_S3_SAVE_PROTOCOL.S3Save(), which
needs LockBox access.

We also can't install the protocol after BdsLibBootViaBootOption()
returns, simply because control is never returned to us.

Therefore modify our EFI_ACPI_S3_SAVE_PROTOCOL implementation so that the
boot script is prepared and installed internally to S3Save().

(The boot script must contain at least one opcode, otherwise
S3BootScriptLib runs into an assertion failure. We add a harmless (no-op)
"information" opcode.)

Laszlo Ersek b017b1b27a OvmfPkg: S3 Suspend: enable creation/saving of an S3 Boot Script
"MdeModulePkg/Universal/Acpi/S3SaveStateDxe/S3SaveStateDxe.inf" produces
the EFI_S3_SAVE_STATE_PROTOCOL which allows creation and saving of an S3
Boot Script, to be replayed in PEI during S3 Resume. The script contains
opcodes and opcode arguments to configure CPU, PCI and IO resources.

S3SaveStateDxe relies on the S3BootScriptLib library. The Null
implementation is not useful for actually saving the boot script, we need
the PiDxeS3BootScriptLib instance.

The PiDxeS3BootScriptLib library instance depends on LockBoxLib,
implemented for OVMF in one of the previous patches.

PiDxeS3BootScriptLib also depends on SmbusLib. For now we opt for the Null
instance of the latter. It means that SMBus commands in the boot script
will have no effect when interpreted during S3 Resume. This should be fine
for OvmfPkg and QEMU.

    S3BootScriptLib [PiDxeS3BootScriptLib]

boot script to EfiACPIMemoryNVS, and links it into the LockBox.

In English, the AcpiS3SaveDxe driver insists on the presence of MP
Services *unconditionally* because,

- if PcdFrameworkCompatibilitySupport is set (the default is false),
- and MP Services are available (which is constant true under the above
  condition),

then the AcpiS3SaveDxe driver would like to get the ACPI_GLOBAL_VARIABLE
variable from the MP Services driver, rather than setting it itself.

The DepEx prevents AcpiS3SaveDxe from loading under OvmfPkg, since we
provide no MP Services implementation. This is particularly broken since
the default PcdFrameworkCompatibilitySupport value is FALSE, making the
entire code that would look at EFI_MP_SERVICES_PROTOCOL dead.

Copy AcpiS3SaveDxe to OvmfPkg, substitute PcdFrameworkCompatibilitySupport
with constant FALSE, and remove all code that becomes dead, including the
DepEx.

Laszlo Ersek 6a7cba79b7 OvmfPkg: implement LockBoxLib
The S3 suspend/resume infrastructure depends on the LockBox library class.
The edk2 tree currently contains Null and SMM instances. The Null instance
is useless, and the SMM instance would require SMM emulation by including
the SMM core and adding several new drivers, which is deemed too complex.

Hence add a simple LockBoxLib instance for OVMF.

jordan.l.justen@intel.com:
 * use PCDs instead of EmuNvramLib
   - clear memory in PlatformPei on non S3 boots
 * allocate NVS memory and store a pointer to that memory
   - reduces memory use at fixed locations

"UefiCpuPkg/Universal/Acpi/S3Resume2Pei/S3Resume2Pei.inf" produces the
EFI_PEI_S3_RESUME2 PEIM-to-PEIM Interface.

When the platform-specific initialization code (in PEI) sets the Boot Mode
to BOOT_ON_S3_RESUME, the DXE IPL (which is the last step in PEI) skips
the DXE phase entirely, and executes the S3 Resume PEIM through the
EFI_PEI_S3_RESUME2 interface instead. (See DxeLoadCore() in
"MdeModulePkg/Core/DxeIplPeim/DxeLoad.c".)

S3Resume2Pei depends on LockBoxLib.

Laszlo Ersek c3cf8daa0f OvmfPkg: QemuBootOrder: handle QEMU's "-boot strict=on" option
When this option is passed to qemu, it appends the word HALT to the
"bootorder" fw_cfg file, as last entry. For example,

  /pci@i0cf8/ethernet@3/ethernet-phy@0
  /pci@i0cf8/scsi@4/disk@0,0
  HALT

The option's purpose is to prevent SeaBIOS from booting from devices that
have not been specified explicitly (with bootindex=N device properties nor
-boot options). When SeaBIOS sees HALT, it doesn't proceed to boot from
default locations (after boot fails from all of the listed locations).

The HALT string currently causes OVMF to reject the entire "bootorder"
fw_cfg contents, with "parse error". This is not good, because since a
recent libvirt commit, libvirt unconditionally passes "-boot strict=on" to
qemu. Consequently, the boot order logic in QemuBootOrder.c has stopped
working for libvirt users.

OVMF's SetBootOrderFromQemu() function actually implements the idea behind
"-boot strict=on": it drops all boot options not in the fw_cfg list. (*)
Therefore, let's recognize HALT, and just do what we've been doing all
along.

(*) Except the UEFI shell, according to the survival policy in
BootOrderComplete(), but the memory mapped UEFI shell is not expressible
via fw_cfg anyway, and its preservation has been requested on edk2-devel.
Hence it's a good boot option to keep in any case.

Laszlo Ersek 2d441ca9cd OvmfPkg: unify PcdMaxVariableSize at 0x2000 bytes
The Linux persistent store (pstore) feature serves, among other things,
for saving the trailing portion of the dmesg in case of a kernel oops. One
backend for the pstore facility is "efivars", ie. non-volatile UEFI
variables.

Linux splits the tail of the dmesg that is to be dumped in 1KB chunks, and
tries to save each chunk as a specially (and differently) named
non-volatile variable. The 1KB chunk size accounts for the variable data
only; Linux expects this size to be available per variable *without*
accounting for the variable name or any firmware-internal overhead.

For non-authenticated (ie. non-secure-boot) variables, OvmfPkg currently
sets the per-variable limit to 0x400 (1KB) through PcdMaxVariableSize.
However this PCD determines the size *before* subtracting the internal
overhead (which is sizeof(VARIABLE_HEADER) == 0x20 bytes for
non-authenticated variables, see
"MdeModulePkg/Include/Guid/VariableFormat.h"), and also before subtracting
the given variable's UCS-2 encoded name (including the trailing 0x0000).

Linux maximizes these special variable names in DUMP_NAME_LEN==52 code
points (including the trailing NUL). Hence we must provide at least

  0x020 == sizeof(VARIABLE_HEADER), for the internal overhead
  0x068 == 2 * 52, for the UCS-2 encoded name, including trailing 0x0000
  0x400 for the variable body
  -----
  0x488 == 1160

bytes in PcdMaxVariableSize, so that Linux's efivars-backed pstore can
work even on non-secure-boot builds of OVMF.

However, as PcdMaxVariableSize=0x2000 has proven reasonable when secure
boot is enabled, it should also be okay when secure boot is disabled; so
for simplicity's sake set PcdMaxVariableSize to 0x2000 unconditionally.

OVMF's SEC runs from read-only memory/flash. When the library is linked

library non-functional.

Extract the stateful, implicitly initialized library implementation into a

Laszlo Ersek 06f1982a64 OvmfPkg: QemuFlashFvbServicesRuntimeDxe: fix out-of-LBA write access
When QemuFlashWrite() is asked to write a range that includes the last
byte of the LBA, then the byte that the function uses to switch the flash
device back to read mode (ROMD mode in KVM speak) actually falls out of
the LBA.

Normally this doesn't cause visible problems. However, if the variable
store and the firmware code are backed by separate flash devices, as
implemented by

  [Qemu-devel] [PATCH v2] hw/i386/pc_sysfw: support two flash drives
  http://thread.gmane.org/gmane.comp.emulators.qemu/243678

plus

  [edk2] [edk2 PATCH] OvmfPkg: split the variable store to a separate file
  http://thread.gmane.org/gmane.comp.bios.tianocore.devel/5045/focus=5046

then the READ_ARRAY_CMD not only reaches a different LBA, it reaches a
different qemu device. This results in a guest reboot soon after.

Fix this by ensuring that we always stay within the LBA just written when
issuing READ_ARRAY_CMD.

These casts are incorrect -- they throw away address bits >=32 before
shifting, which can break the drivers in guests with more than 4GB RAM.

The bug is clearly an artifact of the edk2 coding style, which requires
cast expressions to be written as

  (type) expression

rather than the usual

  (type)expression

The latter correctly reflects that casts have one of the strongest
bindings in C. The former actively obscures that fact. Cf.

  (type) expr1 >> expr2

vs.

  (type)expr1 >> expr2

Make sure we shift before we truncate.

Olivier Martin 6fb4e772a0 OvmfPkg/VirtioMmioDeviceLib: Implement VIRTIO_DEVICE_PROTOCOL for VirtIo Devices over MMIO
Why is the virtio-mmio implementation of the protocol a library,
instead of a driver binary?
The UEFI driver model would encourage to create a virtio-mmio driver
instead of a library. But the reasons why I created a library are:

- A virtio-mmio driver would imply an additional protocol that would
probably have a single attribute field:

typedef struct {
  PHYSICAL_ADDRESS       BaseAddress;
} VIRTIO_MMIO_DEVICE_PROTOCOL;

- There is no (easy) way to scan the available VirtIo devices on a
platform. So, the UEFI firmware for this platform would need a driver
to produce instances for every virtio devices it wants to expose in
UEFI. A single call to a helper library (ie: VirtioMmioDeviceLib)
make the porting easier.

In a later patch we will want to mark the flash memory as a
runtime services data memory range. This will allow a new runtime
services firmware block driver to read & write flash memory when
the OS has set up virtual memory protection.

Since this memory range will appear as runtime services data, we
need to adjust the limit when scanning for PCI window 32 down to
just below the flash device. If we don't adjust the limit, then
the algorithm in PopulateFwData will fail because it will see a
EfiGcdMemoryTypeSystemMemory memory range just below 4GB.

Jordan Justen 9a08997862 OvmfPkg: Add NV Variable storage within FD
This is to prepare for QEMU flash support which will allow
non-volatile variables to be saved in the flash image.

Note two size changes:
 * NV Varstore size increased from 0xc000 to 0xe000
 * FTW work size decreased from 0x2000 to 0x1000

The reason for this change is that the fault-tolerant write
support requires that the work area fit within the block
just before the fault-tolerant write spare storage blocks.
Since QEMU flash blocks have a size of 0x1000, this means
that the maximum FTW work size is 0x1000.

v2:
 * Update commit message and PcdVariableStoreSize

SVN r14770 ("OvmfPkg/PlatformPei: correctly align emulated NV storage")
made sure the emulated NV storage was allocated with correct alignment.

However, the AllocateRuntimePool() -> AllocateAlignedPages() change
flipped the memory type from EfiRuntimeServicesData to
EfiBootServicesData. This causes variable services to access freed storage
at runtime. It crashes Windows 2008 R2 early at boot, for example.

Keep the alignment, but restore the memory type to EfiRuntimeServicesData,
by calling AllocateAlignedRuntimePages().

Jordan Justen c90e37b503 OvmfPkg: Add platform specific reset vector code for X64
KVM has a bug that prevents using page tables in the ROM if the ROM
region utilizes the KVM READONLY memory feature. Therefore, we
avoid using page tables stored in the ROM.

Since OVMF doesn't require memory initialization, we just build
page table entries in RAM at 0x80000 very early in the OVMF boot
process. This address is just after the 'temp RAM' which is set
up by the SEC module.

Currently we only set up 4GB of page tables for OVMF's PEI,
but DxeIpl will build identity mapped page tables that cover all
of the available processor physical address space.

Laszlo Ersek 64378ce170 OvmfPkg: QemuBootOrder: expand relative device paths in UEFI boot options
The prefix matching logic in Match()
[OvmfPkg/Library/PlatformBdsLib/QemuBootOrder.c] expects UEFI boot options
to specify full (absolute) device paths. However, partial (relative)
device paths starting with a HD() node are valid for booting. By not
recognizing them, QemuBootOrder.c misses (and deletes) valid boot options
that would otherwise match the user's preference.

Just like BdsLibBootViaBootOption() expands such paths with the
BdsExpandPartitionPartialDevicePathToFull() function for booting, do the
same in QemuBootOrder.c for prefix matching.

This moves the very first call to
BdsExpandPartitionPartialDevicePathToFull() to an earlier point. The
following call tree explains it:

BdsEntry()                                          [IntelFrameworkModulePkg/Universal/BdsDxe/BdsEntry.c]
  PlatformBdsPolicyBehavior()                       [OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c]
    SetBootOrderFromQemu()                          [OvmfPkg/Library/PlatformBdsLib/QemuBootOrder.c]
      Match()                                       [OvmfPkg/Library/PlatformBdsLib/QemuBootOrder.c]
        BdsExpandPartitionPartialDevicePathToFull() [IntelFrameworkModulePkg/Library/GenericBdsLib/BdsBoot.c]
  BdsBootDeviceSelect()                             [IntelFrameworkModulePkg/Universal/BdsDxe/BdsEntry.c]
    BdsLibBootViaBootOption()                       [IntelFrameworkModulePkg/Library/GenericBdsLib/BdsBoot.c]
      BdsExpandPartitionPartialDevicePathToFull()   [IntelFrameworkModulePkg/Library/GenericBdsLib/BdsBoot.c]

This should be fine, for two reasons:

- the new, earlier call is still under BdsEntry(),

- BdsExpandPartitionPartialDevicePathToFull() expects to be called
  repeatedly, even with the same set of HD() device paths. This function
  implements its own caching for device paths, likely for performance
  reasons.

  That fits this patch well because whatever device paths we expand under
  PlatformBdsPolicyBehavior() can be quickly looked up in
  BdsBootDeviceSelect(), so no work (ie.
  BdsLibConnectAllDriversToAllControllers()) should be wasted.

Laszlo Ersek 4388b0ee0c OvmfPkg: allocate the EFI memory map for Linux as Loader Data
In Linux, efi_memblock_x86_reserve_range() and efi_reserve_boot_services()
expect that whoever allocates the EFI memmap allocates it in Loader Data
type memory. Linux's own exit_boot()-->low_alloc() complies, but
SetupLinuxMemmap() in LoadLinuxLib doesn't.

The memory type discrepancy leads to efi_memblock_x86_reserve_range() and
efi_reserve_boot_services() both trying to reserve the range backing the
memmap, resulting in memmap entry truncation in
efi_reserve_boot_services().

This fix also makes this allocation consistent with all other persistent
allocations in  "OvmfPkg/Library/LoadLinuxLib/Linux.c".

If a flash memory is available, it is unsafe for the page

jljusten e678f9db89 OvmfPkg/SerializeVariablesLib: ignore secure variable restore errors
OvmfPkg's file-based NvVar storage is read back as follows at boot (all
paths under OvmfPkg/Library/):

PlatformBdsPolicyBehavior() [PlatformBdsLib/BdsPlatform.c]
  PlatformBdsRestoreNvVarsFromHardDisk()
    VisitAllInstancesOfProtocol
      for each simple file system:
        VisitingFileSystemInstance()
          ConnectNvVarsToFileSystem() [NvVarsFileLib/NvVarsFileLib.c]
            LoadNvVarsFromFs() [NvVarsFileLib/FsAccess.c]
              ReadNvVarsFile()
+-------------> SerializeVariablesSetSerializedVariables() [SerializeVariablesLib/SerializeVariablesLib.c]
|                 SerializeVariablesIterateInstanceVariables()
|   +-------------> IterateVariablesInBuffer()
|   |                 for each loaded / deserialized variable:
| +-|-----------------> IterateVariablesCallbackSetSystemVariable()
| | |                     gRT->SetVariable()
| | |
| | IterateVariablesInBuffer() stops processing variables as soon as the
| | first error is encountered from the callback function.
| |
| | In this case the callback function is
| IterateVariablesCallbackSetSystemVariable(), selected by
SerializeVariablesSetSerializedVariables().

The result is that no NvVar is restored from the file after the first
gRT->SetVariable() failure.

On my system such a failure
- never happens in an OVMF build with secure boot disabled,
- happens *immediately* with SECURE_BOOT_ENABLE, because the first
  variable to restore is "AuthVarKeyDatabase".

"AuthVarKeyDatabase" has the EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS
attribute set. Since the loop tries to restore it before any keys (PK, KEK
etc) are enrolled, gRT->SetVariable() rejects it with
EFI_SECURITY_VIOLATION. Consequently the NvVar restore loop terminates
immediately, and we never reach non-authenticated variables such as
Boot#### and BootOrder.

Until work on KVM-compatible flash emulation converges between qemu and
OvmfPkg, improve the SECURE_BOOT_ENABLE boot experience by masking
EFI_SECURITY_VIOLATION in the callback:
- authenticated variables continue to be rejected same as before, but
- at least we allow the loop to progress and restore non-authenticated
  variables, for example boot options.

DHCP, PXE, and StdLib socket apps are enabled in OVMF by the sum of:
(a) a UEFI NIC driver,
(b) the generic network stack.

The only choice for (a) used to be the proprietary Intel E1000 driver,
which is cumbersome to obtain and enable.

The iPXE UEFI NIC drivers packaged with qemu-1.5 cover (a) for each NIC
type supported by qemu, and are easy to obtain & configure, even for
earlier qemu versions. Therefore enable (b) per default as well.

This doesn't take up much space; the binaries (b) adds to the firmware
don't seem to need -D FD_SIZE_2MB.

Intel's e1000 driver remains an option, requested by the -D E1000_ENABLE
build flag.

jljusten 635a3ca2a1 OvmfPkg: VirtioLib: populate the Available Ring correctly
The descriptor table (also known as "queue") consists of descriptors. (The
corresponding type in the code is VRING_DESC.)

An individual descriptor describes a contiguous buffer, to be transferred
uni-directionally between host and guest.

Several descriptors in the descriptor table can be linked into a
descriptor chain, specifying a bi-directional scatter-gather transfer
between host and guest. Such a descriptor chain is also known as "virtio
request".

(The descriptor table can host sereval descriptor chains (in-flight virtio
requests) in parallel, but the OVMF driver supports at most one chain, at
any point in time.)

The first descriptor in any descriptor chain is called "head descriptor".
In order to submit a number of parallel requests (= a set of independent
descriptor chains) from the guest to the host, the guest must put *only*
the head descriptor of each separate chain onto the Available Ring.

VirtioLib currently places the head of its one descriptor chain onto the
Available Ring repeatedly, once for each single (head *or* dependent)
descriptor in said descriptor chain. If the descriptor chain comprises N
descriptors, this error amounts to submitting the same entire chain N
times in parallel.

  Available Ring    Descriptor table
    Ptr to head ----> Desc#0     (head of chain)
    Ptr to head --/   Desc#1     (next in same chain)
    ...          /    ...
    Ptr to head /     Desc#(N-1) (last in same chain)

Anatomy of a single virtio-blk READ request (a descriptor chain with three
descriptors):

  virtio-blk request header, prepared by guest:
    VirtioAppendDesc PhysAddr=3FBC6050 Size=16 Flags=1 Head=1232 Next=1232

  payload to be filled in by host:
    VirtioAppendDesc PhysAddr=3B934C00 Size=32768 Flags=3 Head=1232 Next=1233

  host status, to be filled in by host:
    VirtioAppendDesc PhysAddr=3FBC604F Size=1 Flags=2 Head=1232 Next=1234

Processing on the host side -- the descriptor chain is processed three
times in parallel (its head is available to virtqueue_pop() thrice); the
same chain is submitted/collected separately to/from AIO three times:

  virtio_queue_notify vdev VDEV vq VQ#0

  virtio_blk_req_complete req REQ#1 status 0

  virtio_blk_rw_complete req REQ#2 ret 0
  virtio_blk_req_complete req REQ#2 status 0

On my Thinkpad T510 laptop with RHEL-6 as host, this probably leads to
simultaneous DMA transfers targeting the same RAM area. Even though the
source of each transfer is identical, the data is corrupted in the
destination buffer -- the CRC32 calculated over the buffer varies, even
though the origin of the transfers is the same, never rewritten LBA.

  SynchronousRequest Lba=585792 BufSiz=32768 ReqIsWrite=0 Crc32=BF68A44D

The problem is invisible on my HP Z400 workstation.

Fix the request submission by:
- building the only one descriptor chain supported by VirtioLib always at
  the beginning of the descriptor table,
- ensuring the head descriptor of this chain is put on the Available Ring
  only once,
- requesting the virtio spec's language to be cleaned up

Also, add a small delay after the 0xCF9 hard reset request -- on qemu/kvm the

jljusten cb7b12ee3c OvmfPkg: attempt to trigger cold reset through PIIX3 reset control register
The reset requested via the keyboard controller (port 0x64) is actually a
soft reset, but qemu has supported it since forever (plus qemu has not
distinguished between hard reset and soft reset, although this is changing
now). Therefore leave the current IoWrite() in place for compatibility.

On qemu versions with commit 1ec4ba74 ("PIIX3: reset the VM when the Reset
Control Register's RCPU bit gets set"), use the PIIX3 RCR as first choice.
In the future qemu will act differently on soft vs. hard reset requests,
and we should honor that in ResetCold().

  Writing to ioport 0xCF9 on qemu builds prior to commit 1ec4ba74 should
  have no effect. Access to the PCI host config register went through
  several implementations in qemu. Commit 9f6f0423 ("pci_host: rewrite
  using rwhandler") seems safe, both before and after.

  Commit d0ed8076 ("pci_host: convert conf index and data ports to memory
  API") inadvertently dropped the alignment/size check, causing a boot
  regression on NetBSD. It was fixed about six months later in commit
  cdde6ffc, which is current. Translating that to qemu releases, the bug
  was visible from v1.0 to v1.1.0.

On physical hardware cycling between reset methods is sometimes necessary
<http://mjg59.dreamwidth.org/3561.html>. On qemu the port access should
trap immediately.

The INT_MODEL field was present in ACPI 1.0, but eliminated in 2.0.
According to the spec, "platforms should set this field to zero but field
values of one are also allowed to maintain compatibility with ACPI 1.0".
We're setting it to zero.

About Preferred_PM_Profile (taking the place of an 1.0 reserved field),
the specification says:

  This field is set by the OEM to convey the preferred power management
  profile to OSPM. OSPM can use this field to set default power management
  policy parameters during OS installation.

The first two octets are now merged into a 16-bit short; otherwise we've
been treating those as boot architecture flags already (see SVN rev
13615). No change in value.

The fixed feature flags are not modified, only the macro names (expanding
to identical values) are updated to ACPI 2.0.

The following fields are all new in ACPI 2.0:

> +  EFI_ACPI_2_0_GENERIC_ADDRESS_STRUCTURE  ResetReg;
> +  UINT8                                   ResetValue;

We don't claim support for the reset register yet.

> +  UINT64                                  XDsdt;

The 64-bit physical addresses for the FACS and the DSDT are automatically
filled at installation time, see AddTableToList() and DeleteTable() in
"MdeModulePkg/Universal/Acpi/AcpiTableDxe/AcpiTableProtocol.c".

> +  EFI_ACPI_2_0_GENERIC_ADDRESS_STRUCTURE  XPm1aEvtBlk;

> +  EFI_ACPI_2_0_GENERIC_ADDRESS_STRUCTURE  XGpe0Blk;
> +  EFI_ACPI_2_0_GENERIC_ADDRESS_STRUCTURE  XGpe1Blk;

We specify the extended addresses for the required and supported PM1a
Event & Control, PM Timer, and GPE0 Register Blocks, and zero the rest, in
accordance with the ACPI 1.0 fields.

"MEMFD is built so MAINFV's contents will be relocated during the build to
address 0x800000", and it "is a firmware volume with most OVMF code/data
uncompressed. [...] Increasing its size has a little impact on the size of
the resulting firmware image since the blank part of the firmware volume
will compress well."

Let's increase the size to 8MB, since the current limit can get in the way
(for example when building-in the Intel3.5 drivers for e1000 with
-D FD_SIZE_2MB -D NETWORK_ENABLE -D SECURE_BOOT_ENABLE).

jljusten c61a56f208 OvmfPkg: LoadLinuxLib: Zero kernel parameters instead of passing garbage
We're supposed to zero everything in the kernel bootparams that we don't
explicitly initialise, other than the setup_header from 0x1f1 onwards
for a precisely defined length, which is copied from the bzImage.

We're *not* supposed to just pass the garbage that we happened to find
in the bzImage file surrounding the setup_header.

jljusten 61a114ba46 OvmfPkg: LoadLinuxLib: Fix kernel entry for 64-bit OVMF
We currently just jump to offset 0x200 in the kernel image, in 64-bit
mode. This is completely broken. If it's a 32-bit kernel, we'll be
jumping into the compressed data payload.

If it's a 64-bit kernel, it'll work... but the 0x200 offset is
explicitly marked as 'may change in the future', has already changed
from 0x100 to 0x200 in the past with no fanfare, and bootloaders are
instructed that they should look at the ELF header to find the offset.
So although it does actually work today, it's still broken in the
"someone needs to whipped for doing it this way" sense of the word.

In fact, the same bug exists in other bootloaders so the 0x200 offset
probably *is* now set in stone. But still it's only valid to use it if
we *know* it's a 64-bit kernel. And we don't. There *is* no ELF header
that we can look at when we're booting a bzImage, and we can't rely on
it having a PE/COFF header either.

The 32-bit entry point is always guaranteed to work, and we need to
support it anyway. So let's just *always* use it, in 32-bit mode, and
then we don't have to make up some horrible heuristics for detecting
32-bit vs. 64-bit kernels.

jljusten 14430c55c8 OvmfPkg: create \_S3 and \_S4 packages dynamically
Move these states from the DSDT to the SSDT. Override the default
configuration if the host has the following qemu commit:

    commit 459ae5ea5ad682c2b3220beb244d4102c1a4e332
    Author: Gleb Natapov <gleb@redhat.com>
    Date:   Mon Jun 4 14:31:55 2012 +0300

        Add PIIX4 properties to control PM system states.

        This patch adds two things. First it allows QEMU to distinguish
        between regular powerdown and S4 powerdown. Later separate QMP
        notification will be added for S4 powerdown. Second it allows
        S3/S4 states to be disabled from QEMU command line. Some guests
        known to be broken with regards to power management, but allow to
        use it anyway. Using new properties management will be able to
        disable S3/S4 for such guests.

        Supported system state are passed to a firmware using new fw_cfg
        file. The file contains  6 byte array. Each byte represents one
        system state. If byte at offset X has its MSB set it means that
        system state X is supported and to enter it guest should use the
        value from lowest 3 bits.

          001  STR (Suspend To RAM)

Also, this (ie. decimal 1) is the suspend type value that qemu recognizes
as an S3 (suspend to ram) request.

Only the value for PM1a_CNT.SLP_TYP is set (PM1b_CNT.SLP_TYP is left at
zero), since in OVMF we don't report the optional PM1b_EVT_BLK register
block to OSPM. (PM1b_EVT_BLK is defined as 0 in "Platform.h"; see "4.8.1.1

- an updated #include directive in VirtioBlkDxe/VirtioBlk.h,
- and an OvmfPkg.dec package entry in VirtioBlkDxe/VirtioBlk.inf, so that
  the new include directory is searched.

mdkinney d3a24ff551 When SOURCE_DEBUG_ENABLE is set, a TimerLib is linked into the SEC Phase to support the Debug Agent and the TimerLib is mapped into read-only ROM/FLASH.
The TimerLib in the OvmfPkg uses a global variable called mPmba and depends on that global being updated.  This works for modules loaded into memory, but not  XIP modules in ROM/FLASH.

This patch removes the mPmba global variable and instead reads the PIIX4 Power Management Base Address from PCI configuration space when it is needed.  This patch also simplifies the initialization logic in the constructor and introduces #defines to eliminate hard coded values in the function implementations.  According to the PIIX4 documentation, the IO Space enable bit in the PCI Command Register does not have to be set for the Power Management Base Address to be decoded, so that one op has been removed from the constructor.

I have tested this patch with QEMU and verified that the UDK Debugger us functional when SOURCE_DEBUG_ENABLE is set.

jljusten 931a0c74ed OvmfPkg: enable PIIX4 IO space in the PEI phase
I. There are at least three locations in OvmfPkg that manipulate the PMBA
and related PIIX4 registers.

1. MiscInitialization() [OvmfPkg/PlatformPei/Platform.c]
   module type: PEIM -- Pre-EFI Initialization Module
   (a) currently sets the PMBA only: 00.01.3 / 0x40 bits [15:6]

2. AcpiTimerLibConstructor() [OvmfPkg/Library/AcpiTimerLib/AcpiTimerLib.c]
   module type: BASE -- probably callable anywhere after PEI
   (a) sets the PMBA if needed:      00.01.3 / 0x40 bits [15:6]
   (b) sets PCICMD/IOSE if needed:   00.01.3 / 0x04 bit  0
   (c) sets PMREGMISC/PMIOSE:        00.01.3 / 0x80 bit  0

3. AcpiInitialization() [OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c]
   module type: DXE_DRIVER -- Driver eXecution Environment
   (a) sets SCI_EN, which depends on correct PMBA setting from earlier

(
  The relative order of #1 and #3 is dictated minimally by their module
  types. Said relative order can be verified with the boot log:

       27 Loading PEIM at 0x00000822320 EntryPoint=0x00000822580
          PlatformPei.efi
       28 Platform PEIM Loaded
     1259 PlatformBdsInit
     1270 PlatformBdsPolicyBehavior

  Line 28 is printed by InitializePlatform()
  [OvmfPkg/PlatformPei/Platform.c] which is the entry point of that
  module. The other two lines are printed by the corresponding functions
  in "OvmfPkg/Library/PlatformBdsLib/BdsPlatform.c".
)

Currently #2 (AcpiTimerLibConstructor()) is called in a random spot
(whenever it gets loaded from the firmware image) and masks the
insufficient setup in #1. We shouldn't depend on that, PEI should finish
with IO space being fully accessibe. In addition, PEI should program the
same PMBA value as AcpiTimerLib.

II. The PEI change notwithstanding, AcpiTimerLib should stay defensive and
ensure proper PM configuration for itself (either by confirming or by
doing).

III. Considering a possible cleanup/unification of #2 and #3: timer
functions relying on AcpiTimerLibConstructor(),

- MicroSecondDelay()
- NanoSecondDelay()
- GetPerformanceCounter()
- GetPerformanceCounterProperties()
- GetTimeInNanoSecond()

may be called before #3 is reached (in Boot Device Selection phase), so we
should not move the initialization from #2 to #3. (Again, AcpiTimerLib
should contain its own setup.)

We should also not move #3 to an earlier phase -- SCI_EN is premature
unless we're about to boot real soon ("enable generation of SCI upon
assertion of PWRBTN_STS, LID_STS, THRM_STS, or GPI_STS bits").
