- Upstream commit 1d25ff51af5c ("OvmfPkg: add QemuRamfbDxe", 2018-06-14)
7fdf80
  introduced another GOP driver that consumes FrameBufferBltLib, and
7fdf80
  thereby produces a large number of (mostly useless) debug messages at
7fdf80
  the DEBUG_VERBOSE level. Extend the patch to suppress those messages in
7fdf80
  both QemuVideoDxe and QemuRamfbDxe; update the subject accordingly.
7fdf80
  QemuRamfbDxe itself doesn't log anything at the VERBOSE level (see also
7fdf80
  the original commit message at the bottom of this downstream patch).

	QemuVideoDxe (RH only)

7fdf80
In commit 5b2291f9567a ("OvmfPkg: QemuVideoDxe uses
7fdf80
MdeModulePkg/FrameBufferLib"), QemuVideoDxe was rebased to
7fdf80
FrameBufferBltLib.
7fdf80
7fdf80
The FrameBufferBltLib instance added in commit b1ca386074bd
7fdf80
("MdeModulePkg: Add FrameBufferBltLib library instance") logs many
7fdf80
messages on the VERBOSE level; for example, a normal boot with OVMF can
7fdf80
produce 500+ "VideoFill" messages, dependent on the progress bar, when the
7fdf80
VERBOSE bit is set in PcdDebugPrintErrorLevel.
7fdf80
7fdf80
QemuVideoDxe itself doesn't log anything at the VERBOSE level, so we lose
7fdf80
none of its messages this way.
