drm: extract legacy framebuffer remove I got confused every time I audited what that lock_all is doing in there until realizing it's for legacy kms only. Make that a notch more obvious by having 2 entirely different paths. While at it also move the atomic version of this into drm_framebuffer.c, there's no reason it needs to be in drm_atomic.c. That way it becomes a simple static function.

drm: extract drm_atomic_uapi.c This leaves all the commit/check and state handling in drm_atomic.c, while pulling all the uapi glue and the huge ioctl itself into a seprate file. This seems to almost perfectly split the rather big drm_atomic.c file into 2 equal sizes. Also adjust the kerneldoc and type a very terse overview text. v2: Rebase. v3: Fix tiny typo. v4: - Fixup armada, newly converted atomic driver hooray! - Fixup msm/dpu1, newly added too.

drm: Introduce drm_framebuffer_{get,put}() For consistency with other reference counting APIs in the kernel, add drm_framebuffer_get() and drm_framebuffer_put() to reference count DRM framebuffers. Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit. The existing semantic patch for the DRM subsystem-wide conversion is extended to account for these new helpers.

drm: Differentiate the lack of an interface from invalid parameter If the ioctl is not supported on a particular piece of HW/driver combination, report ENOTSUP (aka EOPNOTSUPP) so that it can be easily distinguished from both the lack of the ioctl and from a regular invalid parameter. v2: Across all the kms ioctls we had a mixture of reporting EINVAL, ENODEV and a few ENOTSUPP (most where EINVAL) for a failed drm_core_check_feature(). Update everybody to report ENOTSUPP. v3: ENOTSUPP is an internal errno! It's value (524) does not correspond to a POSIX errno, the one we want is ENOTSUP. However, uapi/asm-generic/errno.h doesn't include ENOTSUP but man errno says "ENOTSUP and EOPNOTSUPP have the same value on Linux, but according to POSIX.1 these error values should be distinct." so use EOPNOTSUPP as its equivalent.

drm: move native byte order quirk to new drm_driver_legacy_fb_format function Turns out we need the pixel format fixup not only for the addfb ioctl, but also for fbdev emulation code. Ideally we would place it in drm_mode_legacy_fb_format(). That would create alot of churn though, and most drivers don't care because they never ever run on a big endian platform. So add a new drm_driver_legacy_fb_format() function instead which looks at the mode_config->quirk_addfb_prefer_host_byte_order flag.

drm: Replace drm_framebuffer plane size functions with its equivalents The functions drm_framebuffer_plane_{width,height} and fb_plane_{width,height} do exactly the same job of its equivalents drm_format_info_plane_{width,height} from drm_fourcc. The only reason to have these functions on drm_framebuffer would be if they would added a abstraction layer to call it just passing a drm_framebuffer pointer and the desired plane index, which is not the case, where these functions actually implements just part of it. In the actual implementation, every call to both drm_framebuffer_plane_{width,height} and fb_plane_{width,height} should pass some drm_framebuffer attribute, which is the same as calling the drm_format_info_plane_{width,height} functions. The drm_format_info_pane_{width,height} functions are much more consistent in both its implementation and its location on code. The kind of calculation that they do is intrinsically derivated from the drm_format_info struct and has not to do with drm_framebuffer, except by the potential motivation described above, which is still not a good justification to have drm_framebuffer functions to calculate it. So, replace each drm_framebuffer_plane_{width,height} and fb_plane_{width,height} call to drm_format_info_plane_{width,height} and remove them.

drm/fourcc: Add char_per_block, block_w and block_h in drm_format_info 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.

drm: Nuke modifier[1-3] It has been suggested that having per-plane modifiers is making life more difficult for userspace, so let's just retire modifier[1-3] and use modifier[0] to apply to the entire framebuffer. Obviosuly this means that if individual planes need different tiling layouts and whatnot we will need a new modifier for each combination of planes with different tiling layouts. For a bit of extra backwards compatilbilty the kernel will allow non-zero modifier[1+] but it require that they will match modifier[0]. This in case there's existing userspace out there that sets modifier[1+] to something non-zero with planar formats.

drm: introduce fb_modifiers_not_supported flag in mode_config If only linear modifier is advertised, since there are many drivers that only linear supported, the DRM core should handle this rather than open-coding in every driver. However, there are legacy drivers such as radeon that do not support modifiers but infer the actual layout of the underlying buffer. Therefore, a new flag fb_modifiers_not_supported is introduced for these legacy drivers, and allow_fb_modifiers is replaced with this new flag. v3: - change the order as follows: 1. add fb_modifiers_not_supported flag 2. add default modifiers 3. remove allow_fb_modifiers flag - add a conditional disable in amdgpu_dm_plane_init() v4: - modify kernel docs v5: - modify kernel docs Signed-off-by: Tomohito Esaki <etom@igel.co.jp> Acked-by: Harry Wentland <harry.wentland@amd.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20220128060836.11216-2-etom@igel.co.jp

drm: Differentiate the lack of an interface from invalid parameter If the ioctl is not supported on a particular piece of HW/driver combination, report ENOTSUP (aka EOPNOTSUPP) so that it can be easily distinguished from both the lack of the ioctl and from a regular invalid parameter. v2: Across all the kms ioctls we had a mixture of reporting EINVAL, ENODEV and a few ENOTSUPP (most where EINVAL) for a failed drm_core_check_feature(). Update everybody to report ENOTSUPP. v3: ENOTSUPP is an internal errno! It's value (524) does not correspond to a POSIX errno, the one we want is ENOTSUP. However, uapi/asm-generic/errno.h doesn't include ENOTSUP but man errno says "ENOTSUP and EOPNOTSUPP have the same value on Linux, but according to POSIX.1 these error values should be distinct." so use EOPNOTSUPP as its equivalent.

These APIs use the _get() and _put() suffixes and will collide with this existing function. Rename the function to drm_mode_object_add() which is a slightly more accurate description of what it does. Also the kerneldoc for this function gives an indication that it's badly named because it doesn't actually acquire a reference to anything.

drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2. This introduces a slight behavioral change to rmfb. Instead of disabling a crtc when the primary plane is disabled, we try to preserve it. Apart from old versions of the vmwgfx xorg driver, there is nothing depending on rmfb disabling a crtc. Vmwgfx' and simple kms helper atomic implementation rejects CRTC enabled without plane, so we can do this safely. If the atomic commit is rejected by the driver then we will still fall back to the old behavior and turn off the crtc. Changes since v1: - Restart completely when rmfb with crtc on fails (Sean Paul).

drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2. This introduces a slight behavioral change to rmfb. Instead of disabling a crtc when the primary plane is disabled, we try to preserve it. Apart from old versions of the vmwgfx xorg driver, there is nothing depending on rmfb disabling a crtc. Vmwgfx' and simple kms helper atomic implementation rejects CRTC enabled without plane, so we can do this safely. If the atomic commit is rejected by the driver then we will still fall back to the old behavior and turn off the crtc. Changes since v1: - Restart completely when rmfb with crtc on fails (Sean Paul).

This patch only converts drm_framebuffer_remove to atomic.

drm: Replace drm_framebuffer plane size functions with its equivalents The functions drm_framebuffer_plane_{width,height} and fb_plane_{width,height} do exactly the same job of its equivalents drm_format_info_plane_{width,height} from drm_fourcc. The only reason to have these functions on drm_framebuffer would be if they would added a abstraction layer to call it just passing a drm_framebuffer pointer and the desired plane index, which is not the case, where these functions actually implements just part of it. In the actual implementation, every call to both drm_framebuffer_plane_{width,height} and fb_plane_{width,height} should pass some drm_framebuffer attribute, which is the same as calling the drm_format_info_plane_{width,height} functions. The drm_format_info_pane_{width,height} functions are much more consistent in both its implementation and its location on code. The kind of calculation that they do is intrinsically derivated from the drm_format_info struct and has not to do with drm_framebuffer, except by the potential motivation described above, which is still not a good justification to have drm_framebuffer functions to calculate it. So, replace each drm_framebuffer_plane_{width,height} and fb_plane_{width,height} call to drm_format_info_plane_{width,height} and remove them.
