The sync_debug.h header is internal, and only used by sw_sync.c. Therefore, SW_SYNC is always defined and there is no need for the stubs. Remove them and make the code simpler. Signed-off-by:

With the previous patch drm_atomic_helper_check_plane_state correctly calculates clipping and the xf86-video-intel ddx is fixed to fall back to GPU correctly when SetPlane fails, we can remove the hack where we try to pan/zoom when out of min/max scaling range. This was already poor behavior where the screen didn't show what was requested, and now instead we reject it outright. This simplifies check_sprite_plane a lot. Changes since v1: - Set crtc_h to the height correctly. - Reject < 3x3 rectangles instead of making them invisible for <gen9. For gen9+ skl_update_scaler_plane will reject them. Signed-off-by:

Instead of relying on a scale which may increase rounding errors, clip src by doing: src * (dst - clip) / dst and rounding the result away from 1, so the new coordinates get closer to 1. We won't need to fix up with a magic macro afterwards, because our scaling factor will never go to the other side of 1. Changes since v1: - Adjust dst immediately, else drm_rect_width/height on dst gives bogus results. Change since v2: - Get rid of macros and use 64-bits math. Signed-off-by:

When calculating limits we want to be as pessimistic as possible, so we have to explicitly say whether we want to round up or down to accurately calculate whether we are below min_scale or above max_scale. Signed-off-by:

adv7511_probe() is never called in atomic context. This function is only set as ".probe" in struct i2c_driver. Despite never getting called from atomic context, adv7511_probe() calls mdelay() to busily wait. This is not necessary and can be replaced with usleep_range() to avoid busy waiting. This is found by a static analysis tool named DCNS written by myself. And I also manually check it. Signed-off-by:

This driver will be used to support Mesa on the Broadcom 7268 and 7278 platforms. V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's complicated CL/shader validation scheme. This massively changes the GEM behavior, so I've forked off to a new driver. v2: Mark SUBMIT_CL as needing DRM_AUTH. coccinelle fixes from kbuild test robot. Drop personal git link from MAINTAINERS. Don't double-map dma-buf imported BOs. Add kerneldoc about needing MMU eviction. Drop prime vmap/unmap stubs. Delay mmap offset setup to mmap time. Use drm_dev_init instead of _alloc. Use ktime_get() for wait_bo timeouts. Drop drm_can_sleep() usage, since we don't modeset. Switch page tables back to WC (debug change to coherent had slipped in). Switch drm_gem_object_unreference_unlocked() to drm_gem_object_put_unlocked(). Simplify overflow mem handling by not sharing overflow mem between jobs. v3: no changes v4: align submit_cl to 64 bits (review by airlied), check zero flags in other ioctls.

I had originally asked Stefan Schake to drop the pad field from the syncobj changes that just landed, because I couldn't come up with a reason to align to 64 bits. Talking with Dave Airlie about the new v3d driver's submit ioctl, we came up with a reason: sizeof() on 64-bit platforms may align to 64 bits, in which case the userspace will be submitting the aligned size and the final 32 bits won't be zero-padded by the kernel. If userspace doesn't zero-fill, then a future ABI change adding a 32-bit field at the end could potentially cause the kernel to read undefined data from old userspace (our userspace happens to use structure initialization that zero-fills, but as a general rule we try not to rely on that in the kernel).

In the func drm_atomic_set_crtc_for_plane, with the current code, if crtc of the plane_state and crtc passed as argument to the func are same, entire func will executed in vein. It will get state of crtc and clear and set the bits in plane_mask. All these steps are not required for same old crtc. Ideally, we should do nothing in this case, this patch handles the same, and causes the program to return without doing anything in such scenario. Signed-off-by:

When this was introduced in commit a519435a Author: Christian König <christian.koenig@amd.com> Date: Tue Oct 20 16:34:16 2015 +0200 dma-buf/fence: add fence_wait_any_timeout function v2 there was a restriction added that this only works if the dma-fence uses the dma_fence_default_wait hook. Which works for amdgpu, which is the only caller. Well, until you share some buffers with e.g. i915, then you get an -EINVAL. But there's really no reason for this, because all drivers must support callbacks. The special ->wait hook is only as an optimization; if the driver needs to create a worker thread for an active callback, then it can avoid to do that if it knows that there's a process context available already. So ->wait is just an optimization, just using the logic in dma_fence_default_wait() should work for all drivers. Let's remove this restriction. Signed-off-by:

The Versatile Express has 8 MB of dedicated video RAM (VRAM) on the motherboard, which is what we should be using for the PL111 if available. On this platform, the memory backplane is constructed so that only this memory will work properly with the CLCD on the motherboard, using any other memory area just gives random snow on the display. The CA9 Versatile Express also has a PL111 instance on its core tile that can address all memory, and this does not have the restriction. The memory is assigned to the device using the memory-region device tree property and a "shared-dma-pool" reserved memory pool like this: reserved-memory { #address-cells = <1>; #size-cells = <1>; ranges; vram: vram@48000000 { compatible = "shared-dma-pool"; reg = <0x48000000 0x00800000>; no-map; }; }; clcd@1f000 { compatible = "arm,pl111", "arm,primecell"; (...) memory-region = <&vram>; }·; Cc: Liviu Dudau <liviu.dudau@arm.com> Cc: Mali DP Maintainers <malidp@foss.arm.com> Reviewed-by:Robin Murphy <robin.murphy@arm.com> Signed-off-by:

The Versatile Express uses a special configuration controller deeply embedded in the system motherboard FPGA to multiplex the two to three (!) display controller instances out to the single SiI9022 bridge. Set up an extra file with the logic to probe to the FPGA mux register on the system controller bus, then parse the device tree to see if there is a CLCD or HDLCD instance on the core tile (also known as the daughterboard) by looking in the root of the device tree for compatible nodes. - If there is a HDLCD on the core tile, and there is a driver for it, we exit probe and deactivate the motherboard CLCD. We do not touch the DVI mux in this case, to make sure we don't break HDLCD. - If there is a CLCD on both the motherboard and the core tile (only the CA9 has this) the core tile CLCD takes precedence and get muxed to the DVI connector. - Only if there is no working graphics on the core tile, the motherboard CLCD is probed and muxed to the DVI connector. Core tile graphics should always take precedence as it can address all memory and is also faster, however the motherboard CLCD is good to have around for diagnostics and testing. It is possible to test the motherboard CLCD by setting the status = "disabled" property on the core tile CLCD or HDLCD. Scale down the Versatile Express to 16BPP so we can support a 1024x768 display despite the bus bandwidth restrictions on this platform. (The motherboard CLCD supports slightly lower resolution.)
