[edk2-devel] [PATCH] OvmfPkg: raise DXEFV size to 14.5 MB in the traditional platform FDFs

["Laszlo Ersek" <lersek@redhat.com>]

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:
