It's lockless, and userspace might chance it underneath us. That's not really a problem, all userspace gets is a slightly dysfunctional lease with the current code. But this might change, and gcc might decide to reload a few too many times, and then boom. So better safe than sorry. v2: Remove the now unused lessor_priv argument from validate_lease() (Keith). v3: Actually add everything ... silly me.

This essentially undoes commit 39868bd7 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Oct 29 08:55:58 2013 +0000 drm: Compact booleans within struct drm_file We do lockless access to these flags everywhere, and it's kinda not a great idea to mix lockless and bitfields. Aside from that gcc isn't generating great code for these. If this ever becomes an issue size-wise, I think we need atomic_t here and atomic bitflag ops.

VGEM doesn't do anything modeset specific, so in a way exposing a primary node is 'wrong'. At the same time, we extensively use if for creating dumb buffers, fences, prime fd <> handle imports/exports. To the point that we explicitly annotate the vgem fence ioctls as DRM_RENDER_ALLOW and have an IGT test which opens the render node. close(drm_open_driver_render(DRIVER_VGEM)) Better late than never, let's flip the switch.

H6 has Synopsys DWC HDMI 2.0 TX PHY. There is no freely available documentation for it, only code found in BSP kernel. However, judging by the code, PHY is very similar to older Synopsys HDMI PHY described in i.MX6 documentation. Most registers seem to be the same. According to i.MX6 documentation, mpll settings are based on pixel clock and are not specific to each SoC. Because of that, mpll table in this commit is based on that documentation and not on BSP code. Other PHY settings were derived from BSP PHY driver code. Signed-off-by:

Currently sun8i-hdmi-phy driver supports only custom PHYs connected to DW HDMI controller. Since newest Allwinner SoCs have unmodified Synopsys PHY, driver has to be reorganized to support them. Variant structure is expanded to allow differentiation between custom and Sysnopsys PHYs and to hold Synopsys PHY settings. Since DW HDMI bridge platform data has different fields for custom and Sysnopsys PHY, function sun8i_hdmi_phy_get_ops() is replaced with sun8i_hdmi_phy_set_ops(). Signed-off-by:

Currently supported Allwinner SoCs with DW HDMI controller have scrambled addresses and read lock. However, that is not true in general. For example, A80 and H6 have normal addresses and normal read access. Move code for unscrambling addresses and unlocking read access to it's own function and call it from init function. Reviewed-by:

Add tests that verify that drm_internal_framebuffer_create creates buffers correctly by creating a dummy drm_device with a mock function for the fb_create callback. To decide if a buffer has been created or not it just checks if fb_create callback has been called for the particular drm_mode_fb_cmd2 that's being tested. Reviewed-by:

If we want to be able to write drmselftests for non-static core functions that are not intended to be used by drivers we need this functions to be exported.

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.

Mali-DP implements a number of tiled yuv formats which are not currently described in drm_fourcc.h. This adds those definitions and describes their memory layout by using the newly added char_per_block, block_w, block_h. Reviewed-by:

Alexandru Gheorghe authored
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:

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. Cc: Jyri Sarha <jsarha@ti.com> Cc: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by:
