Notes about the RHEL-8.1/20190308-89910a39dcfd [edk2-stable201903] ->

RHEL-8.2/20190904-37eef91017ad [edk2-stable201908] rebase:
|
|
|
1dc609 |
|
|
|
1dc609 |
- The previous version of this patch (downstream commit 76b4ac28e975)
|
|
|
1dc609 |
caused a regression (RHBZ#1714446), which was fixed up in downstream
|
|
|
1dc609 |
commit 5a216abaa737 ("ArmVirtPkg: silence DEBUG_VERBOSE masking
|
|
|
1dc609 |
~0x00400000 in QemuRamfbDxe (RH only)", 2019-08-05).
|
|
|
1dc609 |
|
|
|
1dc609 |
Squash the fixup into the original patch. Fuse the commit messages.
|
|
|
1dc609 |
(Acked-by tags are not preserved, lest we confuse ourselves while
|
|
|
1dc609 |
reviewing this rebase.)

Notes about the RHEL-8.0/20180508-ee3198e672e2 ->
|
|
|
7fdf80 |
RHEL-8.1/20190308-89910a39dcfd rebase:
|
|
|
7fdf80 |
|
|
|
7fdf80 |
- new patch, due to upstream commit c64688f36a8b ("ArmVirtPkg: add
|
|
|
7fdf80 |
QemuRamfbDxe", 2018-06-14)
|
|
|
7fdf80 |
|
|
|
7fdf80 |
QemuRamfbDxe uses FrameBufferLib. The FrameBufferBltLib instance added in
|
|
|
7fdf80 |
commit b1ca386074bd ("MdeModulePkg: Add FrameBufferBltLib library
|
|
|
7fdf80 |
instance") logs many messages on the VERBOSE level; for example, a normal
|
|
|
7fdf80 |
boot with ArmVirtQemu[Kernel] can produce 500+ "VideoFill" messages,
|
|
|
7fdf80 |
dependent on the progress bar, when the VERBOSE bit is set in
|
|
|
7fdf80 |
PcdDebugPrintErrorLevel.
|
|
|
7fdf80 |
|
|
|
1dc609 |
Clear the VERBOSE bit without touching other bits -- those other bits
|
|
|
1dc609 |
differ between the "silent" and "verbose" builds, so we can't set them as
|
|
|
1dc609 |
constants.
|
|
|
1dc609 |
|
|
|
7fdf80 |
QemuRamfbDxe itself doesn't log anything at the VERBOSE level, so we lose
|
|
|
1dc609 |
none of its messages, with the VERBOSE bit clear.
