Ard Biesheuvel a21a994f55 MdeModulePkg/DxeIpl ARM AARCH64: Switch to generic handoff code
Now that we have a generic method to manage memory permissions using a
PPI, we can switch to the generic version of the DXE handoff code in
DxeIpl, and drop the ARM specific version.

Ard Biesheuvel 9df2c0a555 MdeModulePkg/DxeIpl: Use memory attribute PPI to remap the stack NX
If the associated PCD is set to TRUE, use the memory attribute PPI to
remap the stack non-executable. This provides a generic method for doing
so, which will be used by ARM and AArch64 as well once they move to the
generic DxeIpl handoff implementation.

Ard Biesheuvel dfacaab57e MdeModulePkg/DxeIpl: Merge EBC, RISCV64 and LOONGARCH code
The Risc-V and LoongArch specific versions of the DXE core handoff code
in DxeIpl are essentially copies of the EBC version (modulo the
copyright in the header and some debug prints in the code).

In preparation for introducing a generic PPI based method to implement
the non-executable stack, let's merge these versions, so we only need to
add this logic once.

Jiaxin Wu 0d382976c2 MdeModulePkg/DxeIpl: Align Page table Level setting with previous level.
System paging 5 level enabled or not can be checked via CR4.LA57, system
preferred Page table Level (PcdUse5LevelPageTable) must align with previous
level for 64bit long mode.

This patch is to do the wise check:
If cpu has already run in 64bit long mode PEI, Page table Level in DXE
must align with previous level.
If cpu runs in 32bit protected mode PEI, Page table Level in DXE is decided
by PCD and feature capability.

Jian J Wang f9d0e5daa0 MdeModulePkg/DxeIplPeim: reserve page 0 for NULL pointer detection
When a boot loader examines the memory map, it can see that location 0
is available memory. If it chooses to use that memory, and
PcdNullPointerDetectionPropertyMask is enabled, use of memory in page 0
will cause an exception. This does occur when running the memtest86
program.

Leaving page 0 available is for legacy support purpose. Since we have
deprecated the support of legacy, the solution is just reserving it so
that it cannot be allocated for other uses.

#GP in the transition from 32-bit PEI to 64-bit DXE due to the code

Simply disabling paging before updating CR3 can solve this conflict.

Jian J Wang 2ac1730bf2 MdeModulePkg/DxeIpl: Mark page table as read-only
This patch will set the memory pages used for page table as read-only
memory after the paging is setup. CR0.WP must set to let it take into
effect.

A simple page table memory management mechanism, page table pool concept,
is introduced to simplify the page table memory allocation and protection.
It will also help to reduce the potential recursive "split" action during
updating memory paging attributes.

The basic idea is to allocate a bunch of continuous pages of memory in
advance as one or more page table pools, and all future page tables
consumption will happen in those pool instead of system memory. If the page
pool is reserved at the boundary of 2MB page and with same size of 2MB page,
there's no page granularity "split" operation will be needed, because the
memory of new page tables (if needed) will be usually in the same page as
target page table you're working on.

And since we have centralized page tables (a few 2MB pages), it's easier
to protect them by changing their attributes to be read-only once and for
all. There's no need to apply the protection for new page tables any more
as long as the pool has free pages available.

Once current page table pool has been used up, one can allocate another 2MB
memory pool and just set this new 2MB memory block to be read-only instead of
setting the new page tables one page by one page.

Two new PCDs PcdPageTablePoolUnitSize and PcdPageTablePoolAlignment are used
to specify the size and alignment for page table pool. For IA32 processor
0x200000 (2MB) is the only choice for both of them to meet the requirement of
page table pool.

Laszlo (lersek@redhat.com) did a regression test on QEMU virtual platform with
one middle version of this series patch. The details can be found at

 https://lists.01.org/pipermail/edk2-devel/2017-December/018625.html

There're a few changes after his work.

Jian J Wang 50255363cb MdeModulePkg/DxeIpl: Enable paging for Stack Guard
Stack guard feature makes use of paging mechanism to monitor if there's a
stack overflow occurred during boot.

This patch will check setting of PCD PcdCpuStackGuard. If it's TRUE, DxeIpl
will setup page table and set the page at which the stack base locates to be
NOT PRESENT. If stack is used up and memory access cross into the last page
of it, #PF exception will be triggered.

Jian J Wang 9189ec20b9 MdeModulePkg/DxeIpl: Implement NULL pointer detection
NULL pointer detection is done by making use of paging mechanism of CPU.
During page table setup, if enabled, the first 4-K page (0-4095) will be
marked as NOT PRESENT. Any code which unintentionally access memory between
0-4095 will trigger a Page Fault exception which warns users that there's
potential illegal code in BIOS.

This also means that legacy code which has to access memory between 0-4095
should be cautious to temporarily disable this feature before the access
and re-enable it afterwards; or disalbe this feature at all.

To follow PI1.4a spec, this patch is to update DxeIpl and
PeiCore to enable S3 resume from temporary memory.
The normal boot path still enforces the permanent memory
requirement.
