If a platform developer follows the PI spec to write an
IncompatiblePciDeviceSupport driver, due to a spec complaince
bug in PciBus driver, the IncompatiblePciDeviceSupport driver
may not work as expected. The patches fix PciBus to follow Spec
to accept Spec defined values.

v2: Use DISABLE_NEW_DEPRECATED_INTERFACES to deprecate macros.
v3: Use MAX_UINT64/MAX_UINTN to replace (UINT64)-1 and (UINTN)-1.

When BarIndex equals to 0xFF, default value 0 is used as the BAR
index. Though PCI_BAR_ALL and MAX_UINT8 shares the same value,
using PCI_BAR_ALL is like to match any BAR not BAR 0, it's more
proper to use MAX_UINT8 here.

PI spec IncompatiblePciSupport part defines (UINT64)-1 as all BARs
and 0 to use existing alignment. PciBus driver didn't accept these
values. It treated 0xFF as all BARs and 0xFFFFFFFFFFFFFFFFULL to use
existing alignment.
The patch changes the code to still accept old values while also
accept values defined in PI spec. So that the driver can provide
backward compatibility and follow spec.

The patch replaces the following macros:
DEVICE_ID_NOCARE (0xFF) --> MAX_UINT64
PCI_ACPI_UNUSED (0) --> 0
PCI_BAR_ALL (0xFF) --> MAX_UINT64
PCI_BAR_NOCHANGE (0) --> 0
PCI_BAR_EVEN_ALIGN --> EVEN_ALIGN (local definition)

Since the PciBus driver was updated to accept Spec defined values
in previous commit, the above replacements don't impact
functionality.

When the VendorId/DeviceId/RevisionId/SubsystemVendorId
/SubsystemDeviceId is MAX_UINTN, IncompatiblePciDeviceSupport
driver doesn't use it to match any IDs.
The patch fixes this bug.
Since PciBus driver always calls IncompatiblePciDeviceSupport
using IDs read from HW, MAX_UINTN is never passed to this
driver.

DEVICE_ID_NOCARE is defined as 0xFFFF but Spec says (UINT64) -1
should be used to match any VendorId/DeviceId/RevisionId/
SubsystemVendorId/SubsystemDeviceId.

PCI_BAR_OLD_ALIGN/PCI_BAR_EVEN_ALIGN/PCI_BAR_SQUAD_ALIGN/
PCI_BAR_DQUAD_ALIGN are defined but Spec doesn't have such
definitions.

PCI_BAR_ALL is defined as 0xFF but Spec says (UINT64) -1 should be
used to match all BARs.

All of the above macros are marked as deprecated.

Hi Jiewen,
   Bug 367 is submitted for  Version Check for capsule update logic error .




In CapsuleAuthenticateSystemFirmware of SignedCapsulePkg\Library\EdkiiSystemCapsuleLib\EdkiiSystemCapsuleLib.c, the following logic seems error

   if (ForceVersionMatch) {
    if (CurrentImageFmpInfo->Version != ImageFmpInfo->Version) {
      *LastAttemptStatus = LAST_ATTEMPT_STATUS_ERROR_INCORRECT_VERSION;
      DEBUG((DEBUG_INFO, "ForceVersionMatch check - fail\n"));
      return EFI_SECURITY_VIOLATION;
    }
  } else {
    if (CurrentImageFmpInfo->Version < ImageFmpInfo->LowestSupportedImageVersion) {
      *LastAttemptStatus = LAST_ATTEMPT_STATUS_ERROR_INCORRECT_VERSION;
      DEBUG((DEBUG_INFO, "LowestSupportedImageVersion check - fail\n"));
      return EFI_SECURITY_VIOLATION;
    }
  }
 

  I think it should be CurrentImageFmpInfo->LowestSupportedImageVersion > ImageFmpInfo->Version

PCI_ACPI_UNUSED expands to 0, so this is fine.

PCI_BAR_OLD_ALIGN used to expand to 0xFFFFFFFFFFFFFFFFULL.

In patch #2, the condtion that checks PCI_BAR_OLD_ALIGN is extended to
cover both 0 (employed here) and the new macro OLD_ALIGN (which is being
introduced in the same patch #2, for the old compat value
0xFFFFFFFFFFFFFFFFULL).

So this looks good too.

PCI_BAR_ALL expands to 0xFF. Patch #2 updates PciBusDxe to cover both
0xFF and MAX_UINT64. Okay.

However, I notice whitespace corruption here: the "//" to the right of
MAX_UINT64 no longer lines up with the rest of the comments.

PCI_BAR_NOCHANGE expands to 0, so this is fine.

Ray, please fix up the whitespace corruption on the MAX_UINT64 line,
before committing the patch. With that fixed:

Any particular reason for not deprecating these two macros? Is it an
oversight, or is it intentional to keep them?

(If they comply with the spec, then replacing them in patch #5 seems
unwarranted.)

These macros comply with the spec so I had no reason to deprecate them.
But I did want to avoid using them in drivers.
Maybe I could just deprecate the two macros PCI_ACPI_UNUSED and PCI_BAR_NOCHANGE.
What do you think?

Any particular reason for not deprecating these two macros? Is it an
oversight, or is it intentional to keep them?

(If they comply with the spec, then replacing them in patch #5 seems
unwarranted.)

Thanks,
Laszlo

I'm fine either way:
- deprecating these two macros (and keeping patch #5 as-is, modulo the
  whitespace fix) sounds good,
- not deprecating these two macros (and then preserving them in OVMF
  too) sounds good as well.

What I don't really understand is, what speaks against using the two
macros if they are not deprecated / against the spec?

But, again, if you deprecate these two as well, that's totally fine by me.

Thanks!
Laszlo
