[edk2-devel] [PATCH 00/14] OvmfPkg: avoid global variables in PEI
Posted by Gerd Hoffmann 1 year, 5 months ago 
Writing to global variables changes the PEI firmware volume which in
turn screws up firmware volume measurements.  Fix OvmfPkg to avoid that,
for the most part by using the PlatformInfoHob instead.

Gerd Hoffmann (14):
  tools_def: remove GCC_IA32_CC_FLAGS/GCC_X64_CC_FLAGS
  tools_def: add -fno-omit-frame-pointer to GCC48_{IA32,X64}_CC_FLAGS
  OvmfPkg/PlatformPei: AmdSev: stop using mPlatformInfoHob
  OvmfPkg/PlatformPei: PeiFv: stop using mPlatformInfoHob
  OvmfPkg/PlatformPei Q35 SMM helpers: stop using mPlatformInfoHob
  OvmfPkg/PlatformPei: PeiMemory: stop using mPlatformInfoHob
  OvmfPkg/PlatformPei: MemTypeInfo: stop using mPlatformInfoHob
  OvmfPkg/PlatformPei: NoExec: stop using mPlatformInfoHob
  OvmfPkg/PlatformPei: Verification: stop using mPlatformInfoHob
  OvmfPkg/PlatformPei: remove mPlatformInfoHob
  OvmfPkg/PlatformPei: remove mFeatureControlValue
  OvmfPkg/DebugLibIoPort: use Rom version for PEI
  OvmfPkg/QemuFwCfgLib: rewrite fw_cfg probe
  OvmfPkg/QemuFwCfgLib: remove mQemuFwCfgSupported +
    mQemuFwCfgDmaSupported

Thanks, this look good to me so i'll pick up the OvmfPkg patches right away.

Liming, Bob, any objections against the BaseTools/ patches? (#1 and #2)
