This changes the fb name from "nouveaufb" to "nouveaudrmfb". Aside: I wonder whether the in_interrupt() check is good enough for the nouveau acceleration. Cargo-cult says drm_can_sleep() is needed, which isn't actually working if you pick a .config without PREEMPT. For the generic fbdev defio support we've gone with offloading everything to a worker. For the non-accel callbacks (set_par, blank and friends) checking for oops_in_progress is good enough to catch all the evil calling contexts. v2: Rebase Acked-by:

Looking at the oldest/most popular drivers ${driver}drmfb seems to be the standard, except i915.ko went with "inteldrmfb". I guess renaming that for consistency won't hurt, it definitely confused me when I started with kms 10 years ago. I hope this never became uapi ... worst case drivers can overwrite it after having called fill_info(). Since subsequent patches change this for some drivers later on in the series, here's the exhaustive list of where all fix.id is used: - /proc/fb which prints the minor number and fix.id name. - per-fb sysfs name file - getfix ioctl, which is used by fbset only to print out the name when dumping information - lots and lots of places in dmesg, anytime anything happens with an fbdev really I think minimal to 0 chances that changing this will screw up a config script or something, since outside of informational message it's not used by anything to identify which fbdev maps to which minor. After all the last fbset release is from 1999, and that predates even devfs I think. v2: Rebase and amend commit message, thanks to Ilia for pointing out that this needs to be spelled out.

The fbdev split between fix and var information is kinda pointless for drm drivers since everything is fixed: The fbdev emulation doesn't support changing modes at all. Create a new simplified helper and use it in the generic fbdev helper code. Follow-up patches will beef it up more and roll it out to all drivers. v2: We need to keep sizes, since they might not match the fb dimensions (Noralf) v3: Fix typo in commit message and remove extraneous line in kerneldoc (Noralf) Reviewed-by:

KMS drivers really should all be able to restore their display state on resume without fbcon helping out. So make this the default. Since I'm not entirely foolish, make it only a default, which drivers can still override. That way when the inevitable regression report happens I can fix things up with a one-liner plus FIXME comment that someone should fix up the suspend/resume code in that driver. But at least all new drivers won't be broken by accident as soon as you turn off fbcon because "suspend/resume worked when I tested it". v2: Keep this for radeon because of commit 18c437ca Author: Alex Deucher <alexander.deucher@amd.com> Date: Tue Nov 14 17:19:29 2017 -0500 Revert "drm/radeon: dont switch vt on suspend" Thanks to Michel Dänzer for pointing this one out.

Maxime Jourdan authored
When the DRM driver for the meson platform was created, the bindings required that the DMC register region was provided. Through those DMC registers, the display driver could configure an IP called "canvas", a video lookup table used by the display IP. It was later discovered that "canvas" is actually an IP shared by other components than display: video decoder, 2D engine.. and that it wasn't possible to keep the canvas code in DRM. Over the past few months, incremental efforts have been deployed to create a standalone meson-canvas driver [1], and the DRM driver was patched to optionally use it if present [2]. This is the final step of those efforts where we simply remove any control over DMC that the meson DRM driver has. Please note that this breaks compatibility with older DTs that only provide the DMC register range but not the amlogic,canvas node.
