V2:
Update DxecorePerformanceLib to report the boot performance table
address instead of records contents.
Updated to convert Pref entry to FPDT record in DXE phase and then
allocate boot performance table to save the record and report
the address of boot performance table to FirmwarePerformanceDxe.

Sorry for the delayed response.
The allocated performance table ( below 4G ) is to save the boot performance data in normal boot and S3 phase.
PEIM FirmwarePerformancePei will get the address of the performance table and update the performance date of S3 phase to the table.
The address need to be handled in PEI phase(32bit), that's the main reason why we allocate it below 4G.
Thanks,
Dandan

Why does this allocation need to live below 4 GB?
If there is no good reason, can we please get rid of this?
If there is a good reason, can we please document it in the code?

The 32-bit PEI + 64-bit DXE combo is specific to X64. You have added
code to a generic library that ASSERT()s if allocating memory below 4
GB fails, breaking non-PC architectures.
So please, fix this. Or at least suggest a way around it so that other
architectures can keep using this library.
This is another consequence of our failure to model the special 32-bit
PEI/64-bit DXE combination using proper PI interfaces, resulting in
these kinds of breakages and open coded 4 GB allocations all
throughout the code. Can we please work on getting this fixed?

How about the code to try allocating <4G memory, then try allocating any memory if failed to allocate <4G memory?
For example, the code snippet in SmbiosDxe.c.
PhysicalAddress = 0xffffffff;
Status = gBS->AllocatePages (
AllocateMaxAddress,
EfiRuntimeServicesData,
EFI_SIZE_TO_PAGES (sizeof (SMBIOS_TABLE_ENTRY_POINT)),
&PhysicalAddress
);
if (EFI_ERROR (Status)) {
DEBUG ((EFI_D_ERROR, "SmbiosCreateTable () could not allocate EntryPointStructure < 4GB\n"));
Status = gBS->AllocatePages (
AllocateAnyPages,
EfiRuntimeServicesData,
EFI_SIZE_TO_PAGES (sizeof (SMBIOS_TABLE_ENTRY_POINT)),
&PhysicalAddress
);
if (EFI_ERROR (Status)) {
return EFI_OUT_OF_RESOURCES;
}
}
Thanks,
Star

The 32-bit PEI + 64-bit DXE combo is specific to X64. You have added
code to a generic library that ASSERT()s if allocating memory below 4
GB fails, breaking non-PC architectures.
So please, fix this. Or at least suggest a way around it so that other
architectures can keep using this library.
This is another consequence of our failure to model the special 32-bit
PEI/64-bit DXE combination using proper PI interfaces, resulting in
these kinds of breakages and open coded 4 GB allocations all
throughout the code. Can we please work on getting this fixed?

It comes to an old question: how to know PEI is 32bit/64bit? But not DXE is 32bit/64bit.
Thanks,
Star

Yes, that should do the trick.
But perhaps we should add something like
AllocatePeiAccessiblePages()
to MemoryAllocationLib, which just uses AllocateMaxAddress or
AllocateAnyPages depending on whether MDE_CPU_X64 is #defined.

we've discussed this question in the past (as you remember :) ) and
people suggested both HOBs and PCDs to expose the "PEI phase max
address" to DXE. All of those ideas were rejected -- I'm unsure why, to
this day --, but assuming people who opposed those ideas are going to
oppose them again, I think Ard's idea is good, about introducing
dedicated MemoryAllocationLib interfaces, for PEI-targeted memory
allocation.
Once drivers adopt these new interfaces, platforms can at least fork the
MemoryAllocationLib instance(s) they need, and customize the PEI phase
max address one way or another.
Thanks,
Laszlo

I could not recall the whole background.
Let us separate the problem into two parts.
1. For this special case in DxeCorePerformanceLib, we at least have approach (although just for short term).
2. For the general problem about whether introducing new interface (PCD and API, seemingly it needs to be in MdePkg), it depends on whether we agree to add new interface and seems need more time to discuss. If yes, then library/driver could be updated to consume it.
If we agree to add new interface, as current instances of MemoryAllocationLib are very nature by phases (PEI, DXE (Uefi/DxeCore), SMM, etc), but the new interface is just needed in DXE (Uefi/DxeCore) instances, how about adding it in UefiLib?
Thanks,
Star

I disagree. The approach involves attempting to allocate below 4 GB,
and fall back to allocating elsewhere if that fails.
On X64, the fallback should not exist. If the first allocation fails,
you will end up with an allocation that PEI may not be able to access,
and you will not get any error or warning about this condition.
On other architectures, allocating below 4 GB unnecessarily may be
wasteful, since it uses up 32-bit addressable that we may prefer to
use for DMA, for instance, given that 32-bit DMA is more efficient
even on PCIe systems.
So even if it makes the error go away, I think it is not a solution at all.

That is a good point, actually. I will look into this.

True. But the current approach is to always assume that PEI is 32-bit,
on every architecture. We can improve upon that by only making this
assumption on X64 builds of DXE, and do so in an abstracted manner
rather than putting the hardcoded limit everywhere in the code.

To: edk2-devel; +Cc: Liming Gao, Star Zeng
V2:
Update SmmCorePerformanceLib to report the buffer address of
boot performance records instead of records contents.
Updated to convert Pref entry to FPDT record in SMM phase and then
export records to FPDT table.

V2:
Update FirmwarePerformanceDxe to receive the address
of performance records instead of records content.
1. Remove the macro EXTENSION_RECORD_SIZE, since the extension
size can be got through PcdExtFpdtBootRecordPadSize.
2. Hook EFI_SW_DXE_BS_PC_READY_TO_BOOT_EVENT to install ACPI table
3. Copy SMM record accord to the allocated size
4. Receive Boot performance table address instead of
contents which are reported DxeCorePerformanceLib.

V2:
Update FirmwarePerformanceSmm to receive the address
of performance records instead of records content.
Receive buffer address of Boot performance records
which are reported by SmmCorePerformanceLib.

Hi, Dandan
I have seen an email named “ [edk2] [PATCH v2 8/8] ShellPkg/Dp: Updated to dump perf log based on FPDT table “ in mail-archive ” and I know there is an update of Dp.
But I feel uncertain that:
- // Determine in which direction the performance counter counts. - TimerInfo.CountUp = (BOOLEAN) (TimerInfo.EndCount >= TimerInfo.StartCount); + TimerInfo.StartCount = 0; + TimerInfo.EndCount = 0xFFFF; + TimerInfo.CountUp = TRUE;
So it looks like we would not use timer count down feature , does it mean we should use count up timer such as TSC or ACPI Timer? Maybe is there any other cause?
I am looking forward your reply! Thanks!
