With CONFIG_X86_SYSFB=y, probing real hw-drivers may result in
resource-conflicts and drivers will refuse to load. A call to
request_mem_region() will fail, if the region overlaps with the mem-region
used by simplefb. The common desktop DRM drivers (intel, nouveau, radeon)
are not affected as they don't reserve their resources, but some others
do, including (nvidiafb, cirrus, ..).
I have validated that this doesn't cause any regressions on the/a
non-x86 platform using simplefb, although given the main point of this
patch is to fix issues on x86, I'm rather hesitant to give a tested-by
tag in case someone looking back interprets it incorrectly:-)
Tested-on-ARM-by: Stephen Warren [off-list ref]
I suppose with CC: stable there's some precedent for a comment after the
tag, so perhaps:
Tested-by: Stephen Warren <redacted> # on ARM only
That works too.
Thanks,
