drm: mali-dp: Enable Mali-DP tiled buffer formats

2018-11-02T09:57:27Z

drm: malidp: Add the size of the superblocks when calculating total

2018-10-05T14:39:51Z

size for AFBC buffers The size of the superblocks being added to the total AFBC buffer size got lost in the upstreaming process. Add it back. Reviewed-by: Ayan Kumar Halder Signed-off-by: Liviu Dudau

drm/arm/malidp: Implemented the size validation for AFBC framebuffers

2018-10-02T11:12:19Z

AFBC buffers include additional metadata which increases the required allocation size. Implement the appropriate size validation and sanity checking for AFBC buffers. Added malidp specific function for framebuffer creation. This checks if the framebuffer has AFBC modifiers and if so, it verifies the necessary constraints on the size, alignment, offsets and pitch. Changes from v2: - Replaced DRM_ERROR() with DRM_DEBUG_KMS() in malidp_verify_afbc_framebuffer_caps() and malidp_verify_afbc_framebuffer_size() Signed-off-by: Ayan Kumar halder Reviewed-by: Brian Starkey Reviewed-by: Liviu Dudau Signed-off-by: Liviu Dudau

drm/arm/malidp: Validate rotations for compressed/uncompressed framebuffers for each layer

2018-10-02T11:11:00Z

Add support for compressed framebuffers that are described using the framebuffer's modifier field. Mali DP uses the rotation memory for the decompressor of the format, so we need to check for space when the modifiers are present.

drm/malidp: Enable MMU prefetch on Mali-DP650

2018-10-02T10:59:36Z

Mali-DP650 supports warming up the SMMU translations, by sending requsts to the SMMU before a buffer is read. There are two modes supported: - PARTIAL: could be enabled when the buffer is composed of 4K or 64K pages, the display hardware will send a configurable number of requests before the actual reading. - FULL: could be enabled when the buffer is composed of 1M or 2M pages, the display hardware will send requests before reading for all pages composing the buffer. This patch adds a mechanism for detecting the page size and set the MMU prefetch mode if possible. Changes since v1: - For imported buffers use the already populated drm_gem_cma_object.sgt instead of calling driver.gem_prime_get_sg_table, which works just for buffers allocated through the gem_cma API.

drm/mali-dp: Implement plane alpha and pixel blend on malidp

2018-10-02T10:54:26Z

Checks the pixel blending mode and plane alpha value when do the plane_check. Mali DP supports blending the current plane with the background either based on the pixel alpha blending mode or by using the layer's alpha value, but not both at the same time. If both case, plane_check will return failed. Sets the HW when doing plane_update accordingly. If plane alpha is the 0xffff, set the pixel blending bits accordingly. If not we'd set ALPHA bit as zero and layer alpha value. Changes since v1: - Introduces to use it in the malidp driver, which depends on the plane alpha patch Changes since v2: - Refines the comments of drm/mali-dp patchset Changes since v3: - Adds hardware limitation check Changes since v4: - Updates on drm/malidp, hardware limitation check only when the format has alpha pixel. - Rebases on drm-misc-next.

drm/malidp: Fix smart layer when doing pm_suspend/resume

2018-10-02T10:54:26Z

Smart layer enable rectangles is set to 1 when the driver is probed, however when doing pm_suspend the value is lost and it's not set again making the SMART_LAYER unusable, fix that by initializing the number of rectangles everytime we do a plane update.

drm/malidp: Fix writeback in NV12

2018-10-02T10:54:26Z

When we want to writeback to memory in NV12 format we need to program the RGB2YUV coefficients. Currently, we don't program the coefficients and NV12 doesn't work at all. This patchset fixes that by programming a sane default(bt709, limited range) as rgb2yuv coefficients. In the long run, probably we need to think of a way for userspace to be able to program that, but for now I think this is better than not working at all or not advertising NV12 as a supported format for memwrite. Changes since v1: - Write the rgb2yuv coefficients only once, since we don't change them at all, just write them the first time NV12 is programmed, suggested by Brian Starkey, here [1] [1] https://lists.freedesktop.org/archives/dri-devel/2018-August/186819.html Signed-off-by: Alexandru Gheorghe Acked-by: Liviu Dudau Signed-off-by: Liviu Dudau

drm: mali-dp: Call drm_crtc_vblank_reset on device init

2018-10-02T10:54:26Z

Currently, if userspace calls drm_wait_vblank before the crtc is activated the crtc vblank_enable hook is called, which in case of malidp driver triggers some warninngs. This happens because on device init we don't inform the drm core about the vblank state by calling drm_crtc_vblank_on/off/reset which together with drm_vblank_get have some magic that prevents calling drm_vblank_enable when crtc is off.

drm/arm/mali: Use drm_fbdev_generic_setup()

2018-09-25T09:31:29Z

The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing.
