Zhiguang Liu dea6002d6e OvmfPkg: Remove applicationProcessorEntryPoint
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4494

Current reset vector uses 0xffffffe0 as AP waking vector, and expects
GenFv generates code aligned on a 4k boundary which will jump to this
location. However, some issues are listed below
1. GenFV doesn't generate code as the comment expects, because GenFv
assumes no modifications are required to the VTF-0 'Volume Top File'.
2. Even if removing VFT0 signature and let GenFv to modify, Genfv is
hard-code using another flash address 0xffffffd0.
3. In the same patch series, AP waking vector code is removed from
GenFv, because no such usage anymore. The existing of first two issues
also approve the usage is not available for a long time.

Therefore, remove AP waking vector related code.

Laszlo Ersek 29cce3356a OvmfPkg/RiscVVirt/README: document direct kernel boot
Direct (fw_cfg) kernel boot works on the RiscVVirt firmware platform too;
I've tested it after extracting the kernel, initrd, and kernel command
line from "openSUSE-Tumbleweed-RISC-V-E20-efi.riscv64.raw". Document this
type of boot, because at least historically, fw_cfg kernel boot was
implemented differently between OVMF and ArmVirtQemu. Thanks: Drew, Sunil.

Laszlo Ersek 6d074d6a10 OvmfPkg: raise DXEFV size to 14.5 MB in the traditional platform FDFs
My usual IA32X64 and X64 builds fail for the NOOPT target, using GCC5:

- IA32X64:

> the required fv image size 0xdef130 exceeds the set fv image size
> 0xd00000

- X64:

> the required fv image size 0xd8f7b8 exceeds the set fv image size
> 0xd00000

NOOPT is important for debugging (less confusing behavior with gdb, and
much less confusing disassembly).

Raise the DXEFV size to 14.5 MB (14 MB would work, but cut it too close
for IA32X64).

After this patch:

- IA32:

> DXEFV [83%Full] 15204352 (0xe80000) total, 12718784 (0xc212c0) used,
> 2485568 (0x25ed40) free

- IA32X64:

> DXEFV [96%Full] 15204352 (0xe80000) total, 14610736 (0xdef130) used,
> 593616 (0x90ed0) free

- X64:

> DXEFV [93%Full] 15204352 (0xe80000) total, 14219192 (0xd8f7b8) used,
> 985160 (0xf0848) free

Tested with:
- IA32, q35, SMM_REQUIRE, Fedora 30 guest
- X64, pc (i440fx), no SMM, RHEL-7.9 guest
- IA32X64, q35, SMM_REQUIRE, RHEL-7.9 guest

Test steps (IA32 and X64):
- configure 3 VCPUs
- boot
- run "taskset -c $I efibootmgr" with $I covering 0..2
- systemctl suspend
- resume from virt-manager
- run "taskset -c $I efibootmgr" with $I covering 0..2

Test steps (IA32X64):
- same, but
- start with only 2 cold-plugged CPUs, and
- hot-plug the third VCPU after initial (cold) boot, before the first
  "taskset -c $I efibootmgr" invocation

Also compared the verbose IA32 fw log from before the patch vs. the one
after (because IA32 builds even without this patch); the changes look
sane:

Pierre Gondois 2f981bddcb MdeModulePkg: Duplicate BaseRngLibTimerLib to MdeModulePkg
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4504

The BaseRngLibTimerLib allows to generate number based on a timer.
This mechanism allows to have a basic non-secure implementation
for non-production platforms.
To bind and identify Random Number Generators implementations with
a GUID, an unsafe GUID should be added. This GUID cannot be added
to the MdePkg unless it is also added to a specification.

To keep the MdePkg self-contained, copy the BaseRngLibTimerLib to
the MdeModulePkg. This will allow to define an unsafe Rng GUID
in a later patch in the MdeModulePkg.

The MdePkg implementation will be removed later. This allows to give
some time to platform owners to switch to the MdeModulePkg
implementation.

Mike Beaton 4d196352f3 OvmfPkg: Revert "Update build.sh to allow building OVMF then running QEMU"
This reverts commit 173a7a7daa

Fixes https://bugzilla.tianocore.org/show_bug.cgi?id=4528

The build.sh qemu option starts the correct qemu executable for the
selected architecture (build.sh -a option, or implicit) and uses the
correct previously built OVMF image for the selected architecture and
build target (build.sh -b option, or implicit).

With this revert, the above step will fail if there is no matching
previously built OVMF image. This is advantageous over rebuilding each
time the build.sh qemu option is used (as in the reverted commit),
because it provides a quick way to run a just-built OVMF image in place,
while:
 a) Starting immediately (saving the time required for a rebuild on each
    usage, if the VM is started multiple times)
 b) Preserving the NVRAM contents between multiple runs (i.e. until the
    image is next rebuilt)

This seems to be due to commit 81dc0d8b4c, which switched to using
PlatformBootManagerLib instead of PlatformBootManagerLibGrub. That pulls
in a dependency on gEfiS3SaveStateProtocolGuid provider being available
(which is asserted for in
BdsPlatform.c:PlatformBootManagerBeforeConsole()/SaveS3BootScript()),
but the libraries that provide it aren't currently included in the

PcdFirstTimeWakeUpAPsBySipi was recently introduced to indicate when the
full INIT-SIPI-SIPI sequence can be skipped for AP bringup. It is true

not simulated. Commit 1d76560146 ("OvmfPkg: Disable
PcdFirstTimeWakeUpAPsBySipi.") added changes to disable it by default
for OvmfPkg, but a similar change was not made for the AmdSev package.
This breaks booting of SEV and SNP guests.

Fix this defaulting PcdFirstTimeWakeUpAPsBySipi to false for AmdSev
package, as was previously done for OvmfPkg variants.

Ard Biesheuvel dfb941d32a OvmfPkg/IoMmuDxe: don't rely on TPLs to manage concurrency
Instead of relying on raising the TPL to protect the critical sections
that manipulate the global bitmask that keeps track of bounce buffer
allocations, use compare-and-exchange to manage the global variable, and
tweak the logic to line up with that.

Given that IoMmuDxe implements a singleton protocol that is shared
between multiple drivers, and considering the elaborate and confusing
requirements in the UEFP spec regarding TPL levels at which protocol
methods may be invoked, not relying on TPL levels at all is a more
robust approach in this case.

Searching for an unused bounce buffer in mReservedMemBitmap and
reserving the buffer by flipping the bit is a critical section
which must not be interrupted.  Raise the TPL level to ensure
that.

Without this fix it can happen that IoMmuDxe hands out the same
bounce buffer twice, causing trouble down the road.  Seen happening
in practice with VirtioNetDxe setting up the network interface (and
calling into IoMmuDxe from a polling timer callback) in parallel with
Boot Manager doing some disk I/O.  An ASSERT() in VirtioNet caught
the buffer inconsistency.

Commit 63c50d3ff2 changed the check that is

the BT instruction but not JZ instruction. The result of a BT instruction
changes the the carry flag (CF) and not the zero flag (ZF). As a result,
the wrong condition is being checked. Update the JZ to a JNC to properly
detect if SEV-ES is active.

Dun Tan a78938f274 OvmfPkg:Remove code that apply AddressEncMask to non-leaf entry
Remove code that sets AddressEncMask for non-leaf entries when
modifing smm page table by MemEncryptSevLib. In FvbServicesSmm
driver, it calls MemEncryptSevClearMmioPageEncMask to clear
AddressEncMask bit in page table for a specific range. In AMD
SEV feature, this AddressEncMask bit in page table is used to
indicate if the memory is guest private memory or shared memory.
But all memory accessed by the hardware page table walker is
treated as encrypted, regardless of whether the encryption bit
is present. So remove the code to set the EncMask bit for smm
non-leaf entries doesn't impact AMD SEV feature.

The reason encryption mask should not be set for non-leaf
entries is because CpuPageTableLib doesn't consume encryption
mask PCD. In PiSmmCpuDxeSmm module, it will use CpuPageTableLib
to modify smm page table in next patch. The encryption mask is
overlapped with the PageTableBaseAddress field of non-leaf page
table entries. If the encryption mask is set for smm non-leaf
page table entries, issue happens when CpuPageTableLib code
use the non-leaf entry PageTableBaseAddress field with the
encryption mask set to find the next level page table.
