2018-09-10drm/rockchip: Allow driver to be shutdown on reboot/kexecMarc Zyngier
Leaving the DRM driver enabled on reboot or kexec has the annoying effect of leaving the display generating transactions whilst the IOMMU has been shut down. In turn, the IOMMU driver (which shares its interrupt line with the VOP) starts warning either on shutdown or when entering the secondary kernel in the kexec case (nothing is expected on that front). A cheap way of ensuring that things are nicely shut down is to register a shutdown callback in the platform driver.

2018-09-10bochs: convert to drm_fb_helper_fbdev_setup/teardownPeter Wu
Currently unloading bochs_drm (after unbinding the vtconsole) results in a warning about a leaked connector: [drm:drm_mode_config_cleanup] *ERROR* connector Virtual-3 leaked! While investigating a potential fix I noticed that a lot of open-coded functionality is already implemented elsewhere, so start converting it: bochs_fbdev_init -> drm_fb_helper_fbdev_setup: trivial (similar impl). bochs_fbdev_fini -> drm_fb_helper_fbdev_teardown: requires unembedding "struct drm_framebuffer" from "struct bochs_framebuffer". Unembedding drm_framebuffer is made easy using drm_gem_fbdev_fb_create which can replace bochs_fbdev_destroy and custom routines in bochs_mm.c. For this to work, the GEM object is moved into "drm_framebuffer". After that, "bochs_framebuffer" is no longer needed and therefore removed. Remove the unused "size" and "initialized" fields from fb, the latter is not necessary as drm_fb_helper_fbdev_teardown can be called even if bochsfb_create fails. This theory was tested by returning early and late (just before drm_gem_fbdev_fb_create). Both scenarios fail gracefully although the latter seems to leak the object from bochsfb_create_object (not a regression). Guess on the reason for the encoder leak: drm_framebuffer_cleanup was previously used, but did not destroy much. drm_fb_helper_fbdev_teardown is now used and calls drm_framebuffer_remove which does a bit more work. Tested with 'echo 0 > /sys/class/vtconsole/vtcon1/bind; rmmod bochs_drm' and also with Xorg + fbdev (startx -> xterm). The latter triggered a warning in ttm_bo_vm_open that existed before, see https://lkml.kernel.org/r/1464000533-13140-4-git-send-email-mstaudt@suse.de Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Peter Wu <peter@lekensteyn.nl> Link: http://patchwork.freedesktop.org/patch/msgid/20180906221810.20170-3-peter@lekensteyn.nl Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2018-09-10drm: refuse ADDFB2 ioctl for broken bigendian driversGerd Hoffmann
Drivers must set the quirk_addfb_prefer_host_byte_order quirk to make the drm_mode_addfb() compat code work correctly on bigendian machines. If they don't they interpret pixel_format values incorrectly for bug compatibility, which in turn implies the ADDFB2 ioctl does not work correctly then. So block it to make userspace fallback to ADDFB.

2018-09-07drm/sun4i: tcon: Add dithering support for RGB565/RGB666 LCD panelsJonathan Liu
The hardware supports dithering on TCON channel 0 which is used for LCD panels. Dithering is a method of approximating a color from a mixture of other colors when the required color isn't available. It reduces color banding artifacts that can be observed when displaying gradients (e.g. grayscale gradients). This may occur when the image that needs to be displayed is 24-bit but the LCD panel is a lower bit depth and does not perform dithering on its own.

2018-09-07drm/sun4i: tcon: Pass drm_encoder * into sun4i_tcon0_mode_set_cpuChen-Yu Tsai
sun4i_tcon0_mode_set_cpu() currently accepts struct mipi_dsi_device * as its second parameter. This is derived from drm_encoder. The DSI encoder is tied to the CPU interface mode of the TCON as a special case. In theory, if hardware were available, we could also support normal CPU interface modes. It is better to pass the generic encoder instead of the specialized mipi_dsi_device, and handle the differences inside the function. Passing the encoder would also enable the function to pass it, or any other data structures related to it, to other functions expecting it. One such example would be dithering support that will be added in a later patch, which looks at properties tied to the connector to determine whether dithering should be enabled or not.

git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux into drm-next omapdrm changes for v4.20 Big amount of changes from Laurent, reworking the driver towards the model used by the other DRM drivers by reverting the direction of many of the operations on the display pipeline. The aim of this work is to allow omapdrm to use the common DRM panels and bridges. Not all of the operations are dealt in these patches, so more work needs to be done. The only change visible to the user should be the change in module dependencies: e.g. earlier a panel module depended on an encoder module, but now the encoder module depends on the panel module, which affects the order in which to unload the modules.

2018-09-06drm: Reject unknown legacy bpp and depth for drm_mode_addfb ioctlChris Wilson
Since this is handling user provided bpp and depth, we need to sanity check and propagate the EINVAL back rather than assume what the insane client intended and fill the logs with DRM_ERROR. v2: Check both bpp and depth match the builtin pixel format, and introduce a canonical DRM_FORMAT_INVALID to reserve 0 against any future fourcc. v3: Mark up DRM_FORMAT_C8 as being {bpp:8, depth:8} Testcase: igt/kms_addfb_basic/legacy-format Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Michel Dänzer <michel.daenzer@amd.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20180905153116.28924-1-chris@chris-wilson.co.uk
2018-09-06drm: fix drm_mode_addfb() on big endian machines.Gerd Hoffmann
Userspace on big endian machhines typically expects the ADDFB ioctl returns a big endian framebuffer. drm_mode_addfb() will call drm_mode_addfb2() unconditionally with little endian DRM_FORMAT_* values though, which is wrong. This patch fixes that. Drivers (both kernel and xorg) have quirks in place to deal with the broken drm_mode_addfb() behavior. Because of this we can't just change drm_mode_addfb() behavior for everybody without breaking things. Add the quirk_addfb_prefer_host_byte_order field to mode_config, so drivers can opt-in.

2018-09-06drm: do not mask out DRM_FORMAT_BIG_ENDIANGerd Hoffmann
framebuffer_check() expects that drm_get_format_info() will not fail if the __drm_format_info() call was successful. That'll work only in case both are called with the same pixel_format value, so masking out the DRM_FORMAT_BIG_ENDIAN flag isn't a good idea.
