Now that we're using the atomic helpers for fence waits, we can use the same codepath as drm_atomic_helper_commit() does for async, getting rid of our custom vc4_commit struct. Signed-off-by:

We should allow SIGIO and things to interrupt us before we get to the no-error stage of the commit process. This code is effectively copied from drm_atomic_helper_commit(). Signed-off-by:

This way drm_atomic_helper_wait_for_fences() will actually do something. The vc4_seqno_cb has been doing the fence waits on V3D manually, so far. Signed-off-by:

With instantaneous high precision vblank timestamping that updates at leading edge of vblank, the emulated "hw vblank counter" from vblank timestamping which increments at leading edge of vblank, and reliable page flip execution and completion at leading edge of vblank, we should meet the requirements for fast vblank irq disable/enable. Testing against rpi-4.12-rc5 Linux kernel with timing measurement equipment indicates this works fine, so allow immediate vblank disable for power saving. For debugging in case of unexpected trouble, booting with kernel cmdline option drm.vblankoffdelay=0 would keep vblank irqs on to approximate old behavior. v2: Respin onto drm-misc-next, per Eric's suggestion. Drop !vc4->firmware_kms check, as the firmware_kms implementation does not exist in upstream. Signed-off-by:Mario Kleiner <mario.kleiner.de@gmail.com> Cc: Eric Anholt <eric@anholt.net> Reviewed-by:

Now that we have a callback to check if crtc supports a given mode we can use it in arcpgu so that we restrict the number of probbed modes to the ones we can actually display. This is specially useful because arcpgu crtc is responsible to set a clock value in the commit() stage but unfortunatelly this clock does not support all the needed ranges. Also, remove the atomic_check() callback as mode_valid() callback will be called before. Signed-off-by:

VBLANK events are missed when the CRTC is being disabled because the driver does not wait till the end of the frame before stopping the HVS and PV blocks. In this case, we should explicitly issue a VBLANK event if there's one waiting. Signed-off-by:

I'm still mildly unhappy with the split between fops and ioctls, but I still think having the ioctls in the uapi chapter makes more sense.

The magic switching between proper pci driver and shadow-attach isn't useful anymore since there's no ums+kms drivers left. Let's split this up properly, calling pci_register_driver for kms drivers and renaming the shadow-attach init to drm_legacy_pci_init/exit. Acked-by:

Since commit ca8e2ad7 Author: Thierry Reding <treding@nvidia.com> Date: Fri Apr 11 15:23:00 2014 +0200 drm: Introduce drm_dev_set_unique() the ->set_busid callback is optional. On top of that the udl one isn't really fully compliant with the drm uabi, but since only modesetting ever binds to it (there's no 3d accel on udl) it doesn't matter. Still, can't harm to aling and use the default used by everyone else. Acked-by:

Unify and review everything, plus make sure it's all correct markup. Drop the kernel-doc for internal functions. Also rework the overview section, it's become rather outdated. Unfortuantely the kernel-doc in drm_driver isn't rendered yet, but that will change as soon as drm_driver is kernel-docified properly. Also document properly that drm_vblank_cleanup is optional, the core calls this already. v2: Make it clear that cleanup happens in drm_dev_fini for drivers with their own ->release callback (Thierry).

This allows mesa to set the tiling format for a BO and have that tiling format be respected by mesa on the other side of an import/export (and by vc4 scanout in the kernel), without defining a protocol to pass the tiling through userspace. Signed-off-by:
Dave Airlie <airlied@redhat.com>

Eric Anholt authored
The T tiling format is what V3D uses for textures, with no raster support at all until later revisions of the hardware (and always at a large 3D performance penalty). If we can't scan out V3D's format, then we often need to do a relayout at some stage of the pipeline, either right before texturing from the scanout buffer (common in X11 without a compositor) or between a tiled screen buffer right before scanout (an option I've considered in trying to resolve this inconsistency, but which means needing to use the dirty fb ioctl and having some update policy). T-format scanout lets us avoid either of those shadow copies, for a massive, obvious performance improvement to X11 window dragging without a compositor. Unfortunately, enabling a compositor to work around the discrepancy has turned out to be too costly in memory consumption for the Raspbian distribution. Because the HVS operates a scanline at a time, compositing from T does increase the memory bandwidth cost of scanout. On my 1920x1080@32bpp display on a RPi3, we go from about 15% of system memory bandwidth with linear to about 20% with tiled. However, for X11 this still ends up being a huge performance win in active usage. This patch doesn't yet handle src_x/src_y offsetting within the tiled buffer. However, we fail to do so for untiled buffers already. Signed-off-by:

According to the eLCDIF initialization steps listed in the MX6SX Reference Manual the eLCDIF block reset is mandatory. Without performing the eLCDIF reset the display shows garbage content when the kernel boots. In earlier tests this issue has not been observed because the bootloader was previously showing a splash screen and the bootloader display driver does properly implement the eLCDIF reset. Add the eLCDIF reset to the driver, so that it can operate correctly independently of the bootloader. Tested on a imx6sx-sdb board. Cc: <stable@vger.kernel.org> Signed-off-by:
