A relative large set of various improvements for vmwgfx.

DRM_VMW_EVENT_FENCE_SIGNALED (struct drm_vmw_event_fence) and DRM_EVENT_VBLANK (struct drm_event_vblank) pass timestamps in 32-bit seconds/microseconds format. As of commit c61eef72 ("drm: add support for monotonic vblank timestamps"), other DRM drivers use monotonic times for drm_event_vblank, but vmwgfx still uses CLOCK_REALTIME for both events, which suffers from the y2038/y2106 overflow as well as time jumps. For consistency, this changes vmwgfx to use ktime_get_ts64 as well, which solves those problems and avoids the deprecated do_gettimeofday() function. This should be transparent to to user space, as long as it doesn't compare the time against the result of gettimeofday(). Signed-off-by:

We were relying on the pinned screen object backup buffer to be destroyed when not used. But if we hold a copy of the atomic state, like when hibernating, the backup buffer might not be destroyed since it's refcounted by the atomic state. This causes us to hibernate with a buffer pinned in VRAM. Fix this by only having the buffer pinned when it is actually used by a screen object. Signed-off-by:

For legacy surfaces, they were previously registered as device resources when the driver resources were created. Since they are evictable we instead register them as device resources once they are created on the device, just like for guest-backed surfaces. This has implications during hibernation where we can't hibernate with device resources active. Signed-off-by:

It was used to early block fbdev dirty processing. Replace it with an unprotected check of the par->dirty.active field. While this might race with the vmw_fb_off() function, we do a protected check later so the race will at worst lead to grabbing and releasing a couple of locks. Signed-off-by:

fbdev framebuffers were previously pinned to be able to keep them mapped across updates. This commit introduces a mechanism that instead revalidates the map on each update, keeping the map cached across updates. The cached map is torn down if the underlying pages change. Typically on buffer object moves and swapouts. This should be nicer to the system when we have resource contention. Testing done: Basic fbdev functionality under Fedora 27. Signed-off-by:

The start / stop and preempt commands don't honor the context argument but rather acts on all available contexts. Also add detection for context 1 availability. Note that currently there's no driver interface for submitting buffers using the high-priority command queue (context 1). Testing done: Change the default context for command submission to 1 instead of 0, verify basic desktop functionality including faulty command injection and recovery. Signed-off-by:

This blit was previously performed using two large vmaps, one of which was teared down and remapped on each blit. Use the more resource- conserving TTM cpu blit instead. The blit is used in boundary-box computing mode which makes it possible to minimize the bounding box used in host operations. Signed-off-by:

The utility uses kmap_atomic() instead of vmapping the whole buffer object. As a result there will be more book-keeping but on some architectures this will help avoid exhausting vmalloc space and also avoid expensive TLB flushes. The blit utility also adds a provision to compute a bounding box of changed content, which is very useful to optimize presentation speed of ill-behaved applications that don't supply proper damage regions, and for page-flips. The cost of computing the bounding box is not that expensive when done in a cpu-blit utility like this. Signed-off-by:

The current limit of 2 leads to some GPU idle times, as the usual IRQ latency leads to up to 3 jobs getting signaled at once with some standard workloads. A larger HW job limit might lead to slightly worse QoS, but we accept that to not sacrifice GPU throughput in the common case. Signed-off-by:Lucas Stach <l.stach@pengutronix.de>

Use drm_plane_helper_check_update also for the cursor plane. Some applications, like gdm on gnome shell still uses cursor front-buffer like rendering without notifying the kernel.

drm/tegra: Changes for v4.17-rc1 This fixes mmap() for fbdev devices by providing a custom implementation based on the KMS variant. This is a fairly exotic case these days, hence why it is not flagged for stable. There is also support for dedicating one of the overlay planes to serve as a hardware cursor on older Tegra that did support hardware cursors but not RGBA formats for it. Planes will now also export the IN_FORMATS property by supporting the various block-linear tiling modifiers for RGBA pixel formats. Other than that, there's a bit of cleanup of DMA API abuse, use of the private object infrastructure for global state (rather than subclassing atomic state objects) and an implementation of ->{begin,end}_cpu_access callbacks for PRIME exported buffers, which allow users to perform cache maintenance on these buffers. * tag 'drm/tegra/for-4.17-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: prime: Implement ->{begin,end}_cpu_access() drm/tegra: gem: Map pages via the DMA API drm/tegra: hub: Use private object for global state drm/tegra: fb: Properly support linear modifier drm/tegra: plane: Support format modifiers drm/tegra: dc: Dedicate overlay plane to cursor on older Tegra's drm/tegra: plane: Make tegra_plane_get_overlap_index() static drm/tegra: fb: Implement ->fb_mmap() callback drm/tegra: gem: Make __tegra_gem_mmap() available more widely drm/tegra: gem: Reshuffle declarations -

Now that we have the guarantee that we will have only a single YUV plane, actually support them. The way it works is not really straightforward, since we first need to enable the YUV mode in the plane that we want to setup, and then we have a few registers to setup the YUV buffer and parameters. We also need to setup the color correction to actually have something displayed. Reviewed-by:

The Allwinner A80 SoC has 2 documented TCONs. The display pipeline diagram from the user manual shows a third TCON, but it's missing an interrupt line, and its registers are not explained either. It's also not used in Allwinner's vendor BSP. The first TCON only has channel 0, for LCD panel output. The TCON hardware setup is peculiar in that the eDP reset must also be deasserted to allow access to the TCON. How the eDP module is wired in the SoC itself is never explained. The second TCON only has channel 1, and its output is connected to the HDMI encoder block. This patch adds a "needs_edp_reset" field to the tcon quirks structure, and adds quirks and compatible strings for the 2 documented TCONs. Signed-off-by:

The display pipeline on the A80 SoC has what is called the Detail Enhancement Unit, or DEU for short, block in between the display frontend and backend. This unit can sharpen images in both luma and chroma channels. It seems to also do colorspace conversion. This patch adds the device tree binding for this hardware block. Reviewed-by:

Chen-Yu Tsai authored
The A80 has 2 or 3 TCONs. The documentation and vendor kernel are very vague about the third TCON, to the point that it might not exist. In the documentation, the first TCON is missing channel 1, and the second is missing channel 0. However the vendor kernel seems to be able to use them regardless. Here we model them like the old TCONs. An oddity is that TCON0 requires the reset control for the eDP block to be deasserted, for any register access to stick. This patch adds compatible strings for TCON0 and TCON1, with TCON0 requiring an extra "edp" reset control. Reviewed-by:

These macros are similar to the DRM_<LEVEL> with the addition of a struct device * to the arguments. Convert the single drm_dev_printk function into 2 separate functions. drm_dev_printk with a KERN_<LEVEL> * for generic use and drm_dev_dbg for conditional masked use. Remove the __func__ argument and use __builtin_return_address(0) to be similar to the DRM_<LEVEL> macros uses. Convert the DRM_DEV_<LEVEL> macros to remove now unnecessary arguments and use a consistent style. These macros are rarely used in the generic gpu/drm code so the code size does not change much for a defconfig, but when more drivers are enabled, there is ~4k savings. Many of these macros have no existing use at all. $ size -t drivers/gpu/drm/built-in.a | tail -1 1877530 44651 995 1923176 1d5868 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 1877527 44651 995 1923173 1d5865 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 17166750 2689238 108352 19964340 130a1b4 (TOTALS) $ size -t drivers/gpu/drm/built-in.a | tail -1 17168888 2691734 108352 19968974 130b3ce (TOTALS) Signed-off-by:
