The changes made in below mentioned commit removed CONFIG_PM containers from drivers/video/fbdev/aty/atyfb_base.c but not from drivers/video/fbdev/aty/atyfb.h for respective callbacks. This resulted in error for implicit declaration for those callbacks. Fixes: 348b2956 ("fbdev: aty: use generic power management") Signed-off-by:

GPU drivers need this in their shrinkers, to be able to throw out mmap'ed buffers. Note that we also need dma_resv_lock in shrinkers, but that loop is resolved by trylocking in shrinkers. So full hierarchy is now (ignore some of the other branches we already have primed): mmap_read_lock -> dma_resv -> shrinkers -> i_mmap_lock_write I hope that's not inconsistent with anything mm or fs does, adding relevant people.

Thomas Zimmermann authored
This change simplifies ast's modesetting code. The display mode is now programmed from within the CRTC's atomic_enable(), which only runs if we actually want to program the mode. Corresponding code in atomic_flush() is being removed. Also removed is atomic_begin(), which serves no purpose at all. Signed-off-by:

Thomas Zimmermann authored
The ast HW cursor requires the primary plane and CRTC to display at a valid mode and format. This is not the case while switching display modes, which can lead to the screen turing permanently dark. As a workaround, the ast driver now disables active planes while the mode or format switch takes place. It also synchronizes with the vertical refresh to give CRTC and planes some time to catch up on each other. The active planes planes (primary or cursor) will be re-enabled by each plane's atomic_update() function. v3: * move the logic into the CRTC's atomic_disable function v2: * move the logic into the commit-tail function Signed-off-by:

Thomas Zimmermann authored
The atomic modesetting code tried to distinguish format changes from full modesetting operations. But the implementation was buggy and the format registers were often updated even for simple pageflips. Fix this problem by handling format changes in the primary plane's update function. v3: * program format in primary plane's update function Signed-off-by:

The lcdif IP does not support a framebuffer pitch (stride) other than framebuffer width. Check for equality and reject the framebuffer otherwise. This prevents a distorted picture when using 640x800 and running the Mesa graphics stack. Mesa tries to use a cache aligned stride, which leads at that particular resolution to width != stride. Currently Mesa has no fallback behavior, but rejecting this configuration allows userspace to handle the issue correctly. Fixes: 45d59d70 ("drm: Add new driver for MXSFB controller") Signed-off-by:

The get_edid() callback can be triggered anytime by an ioctl, i.e drm_mode_getconnector (ioctl) -> drm_helper_probe_single_connector_modes -> drm_bridge_connector_get_modes -> ps8640_bridge_get_edid Actually if the bridge pre_enable() function was not called before get_edid(), the driver will not be able to get the EDID properly and display will not work until a second get_edid() call is issued and if pre_enable() is called before. The side effect of this, for example, is that you see anything when `Frecon` starts, neither the splash screen, until the graphical session manager starts. To fix this we need to make sure that all we need is enabled before reading the EDID. This means the following: 1. If get_edid() is called before having the device powered we need to power on the device. In such case, the driver will power off again the device. 2. If get_edid() is called after having the device powered, all should just work. We added a powered flag in order to avoid recurrent calls to ps8640_bridge_poweron() and unneeded delays. 3. This seems to be specific for this device, but we need to make sure the panel is powered on before do a power on cycle on this device. Otherwise the device fails to retrieve the EDID.

Ingenic SoCs are most notably used in cheap chinese handheld gaming consoles. There, the games and applications generally render in software directly into GEM buffers. Traditionally, GEM buffers are mapped write-combine. Writes to the buffer are accelerated, and reads are slow. Application doing lots of alpha-blending paint inside shadow buffers, which is then memcpy'd into the final GEM buffer. On recent Ingenic SoCs however, it is much faster to have a fully cached GEM buffer, in which applications paint directly, and whose data is invalidated before scanout, than having a write-combine GEM buffer, even when alpha blending is not used. Add an optional 'cached_gem_buffers' parameter to the ingenic-drm driver to allow GEM buffers to be mapped fully-cached, in order to speed up software rendering. v2: Use standard noncoherent DMA APIs v3: Use damage clips instead of invalidating full frames v4: Avoid dma_pgprot() which is not exported. Using vm_get_page_prot() is enough in this case. v5: - Avoid calling drm_gem_cma_prime_mmap(). It has the side effect that an extra object reference is obtained, which causes our dumb buffers to never be freed. It should have been drm_gem_cma_mmap_obj(). However, our custom mmap function only differs with one flag, so we can cleanly handle both modes in ingenic_drm_gem_mmap(). - Call drm_gem_vm_close() if drm_mmap_attrs() failed, just like in drm_gem_cma_mmap_obj().

We update the timestamping constants per-crtc explicitly in intel_crtc_update_active_timings(). Furtermore the helper will use uapi.adjusted_mode whereas we want hw.adjusted_mode. Thus let's drop the helper call an rely on what we already have in intel_crtc_update_active_timings(). We can now also drop the hw.adjusted_mode -> uapi.adjusted_mode copy hack that was added to keep the helper from deriving the timestamping constants from the wrong thing. Signed-off-by:
