2018-11-05drm/sun4i: Add basic support for DE3Jernej Skrabec9-17/+202
Display Engine 3 is an upgrade of DE2 with new features like support for 10 bit color formats and support for AFBC. Most of DE2 code works with DE3, except some small details. Implement basic support for DE3. Support for 10 bit colort formats and AFBC, among others missing features, will be added later.

2018-11-02drm: Extend framebuffer_check to handle formats with cpp/char_per_block 0Alexandru Gheorghe1-1/+7
For formats that are supported only with non-linear modifiers it doesn't make to much sense to define cpp or char_per_block, so that will be set to 0. This patch adds a restriction to force having a modifier attached when cpp/char_per_block is 0, and to bypass checking the pitch restriction. This had been discussed here.

2018-11-02drm/fourcc: Add char_per_block, block_w and block_h in drm_format_infoAlexandru Gheorghe6-9/+148
For some pixel formats .cpp structure in drm_format info it's not enough to describe the peculiarities of the pixel layout, for example tiled formats or packed formats at bit level. What's implemented here is to add three new members to drm_format_info that could describe such formats: - char_per_block[3] - block_w[3] - block_h[3] char_per_block will be put in a union alongside cpp, for transparent compatibility with the existing format descriptions. Regarding, block_w and block_h they are intended to be used through their equivalent getters drm_format_info_block_width / drm_format_info_block_height, the reason of the getters is to abstract the fact that for normal formats block_w and block_h will be unset/0, but the methods will be returning 1. Additionally, convenience function drm_format_info_min_pitch had been added that computes the minimum required pitch for a given pixel format and buffer width. Using that the following drm core functions had been updated to generically handle both block and non-block formats: - drm_fb_cma_get_gem_addr: for block formats it will just return the beginning of the block. - framebuffer_check: Use the newly added drm_format_info_min_pitch. - drm_gem_fb_create_with_funcs: Use the newly added drm_format_info_min_pitch. - In places where is not expecting to handle block formats, like fbdev helpers I just added some warnings in case the block width/height are greater than 1. Changes since v3: - Add helper function for computing the minimum required pitch. - Improve/cleanup documentation Changes since v8: - Fixed build on 32bits arm architectures, with: - return DIV_ROUND_UP((u64)buffer_width * info->char_per_block[plane], + return DIV_ROUND_UP_ULL((u64)buffer_width * info->char_per_block[plane], Reviewed-by: Brian Starkey <brian.starkey@arm.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Alexandru Gheorghe <alexandru-cosmin.gheorghe@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181101170055.5433-1-alexandru-cosmin.gheorghe@arm.com
2018-11-02drm/panel: Add simple panel mode for the ARM RTSMLinus Walleij1-0/+30
Having failed any attempts at a more generic solution, I fall back to the very specific solution: define a simple panel for the ARM RTSM emulated platforms. I am doing this so we can convert all old users from the previous fbdev driver to the PL111 DRM driver. This works fine as far as I can test, provided the device tree for RTSM AEMv8 is augmented accordingly.

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.
