The RK3066 HDMI TX serves as interface between a LCD Controller and a HDMI bus. A HDMI TX consists of one HDMI transmitter controller and one HDMI transmitter PHY. The interface has three (3) 8-bit data channels which can be configured for a number of bus widths (8/10/12/16/20/24-bit) and different video formats (RGB, YCbCr). Features: HDMI version 1.4a, HDCP revision 1.4 and DVI version 1.0 compliant transmitter. Supports DTV resolutions from 480i to 1080i/p HD. Master I2C interface for a DDC connection. HDMI TX supports multiple power save modes. The HDMI TX input can switch between LCDC0 and LCDC1. (Sound support is not included in this patch) Signed-off-by:

This patch moves the virtio_gpu_cmd_create_resource() call (which notifies the host about the new resource created) into the virtio_gpu_object_create() function. That way we can call virtio_gpu_cmd_create_resource() before ttm_bo_init(), so the host already knows about the object when ttm initializes the object and calls our driver callbacks. Specifically the object is already created when the virtio_gpu_ttm_tt_bind() callback invokes virtio_gpu_object_attach(), so the extra virtio_gpu_object_attach() calls done after virtio_gpu_object_create() are not needed any more. The fence support for the create ioctl becomes a bit more tricky though. The code moved into virtio_gpu_object_create() too. We first submit the (fenced) virtio_gpu_cmd_create_resource() command, then initialize the ttm object, and finally attach just created object to the fence for the command in case it didn't finish yet.

Gerd Hoffmann authored
Create virtio_gpu_object_params, use that to pass object parameters to virtio_gpu_object_create. This is just the first step, followup patches will add more parameters to the struct. The plan is to use the struct for all object parameters. Drop unused "kernel" parameter for virtio_gpu_alloc_object(), it is unused and always false. Also drop "pinned" parameter. virtio-gpu doesn't shuffle around objects, so effecively they all are pinned anyway. Hardcode TTM_PL_FLAG_NO_EVICT so ttm knows. Doesn't change much for the moment as virtio-gpu supports TTM_PL_FLAG_TT only so there is no opportunity to move around objects. That'll probably change in the future though. Signed-off-by:

Gerd Hoffmann authored
Drop the dummy ttm backend implementation, add a real one for TTM_PL_FLAG_TT objects. The bin/unbind callbacks will call virtio_gpu_object_{attach,detach}, to update the object state on the host side, instead of invoking those calls from the move_notify() callback. With that in place the move and move_notify callbacks are not needed any more, so drop them. Signed-off-by: -

Looks like EDID_QUIRK_FIRST_DETAILED_PREFERRED never did anything. Its counterpart in f86EdidModes.c is properly hooked up but somehow that functionality was lost when it was copied into the kernel.

Remove the unused DRM_DISPLAY_INFO_LEN from the uapi headers. I presume the original plan was to expose the display name via getconnector, but looks like that never happened. So we have the define for the length of the string but no string anywhere. A quick scan didn't seem to reveal userspace referencing this so hopefully we can just nuke it. Signed-off-by:

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.

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.
