2019-12-05video: constify fb ops across all driversJani Nikula
Now that the fbops member of struct fb_info is const, we can start making the ops const as well. This does not cover all drivers; some actually modify the fbops struct, for example to adjust for different configurations, and others do more involved things that I'd rather not touch in practically obsolete drivers. Mostly this is the low hanging fruit where we can add "const" and be done with it. v3: - un-constify atyfb, mb862xx, nvidia and uvesabf (0day) v2: - fix typo (Christophe de Dinechin) - use "static const" instead of "const static" in mx3fb.c - also constify smscufx.c Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com

Now that we no longer modify the fbops, or hold non-const pointers to it, we can make it const. After this, we can start making the fbops const all over the place.

2019-12-03video: fb_defio: preserve user fb_opsJani Nikula
Modifying fb_ops directly to override fb_mmap with fb_deferred_io_mmap and then resetting it to NULL afterwards causes problems all over the place. First, it prevents making the fbops member of struct fb_info a const pointer, which means we can't make struct fb_ops const anywhere. Second, a few places have to go out of their way to restore the original fb_mmap pointer that gets reset to NULL. Since the only user of the fbops->fb_mmap hook is fb_mmap() in fbmem.c, call fb_deferred_io_mmap() directly when deferred IO is enabled, and avoid modifying fb_ops altogether. Simply use info->fbdefio to determine whether deferred IO should be used or not. This should be accurate enough for all use cases, although perhaps not pedantically correct. v2: Simplify considerably by calling fb_deferred_io_mmap() directly (Daniel, Ville) Cc: Jaya Kumar <jayalk@intworks.biz> Cc: linux-fbdev@vger.kernel.org Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Acked-by: Noralf Trønnes <noralf@tronnes.org> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/022c82429da15d6450ff9ac1a897322ec3124db4.1575022735.git.jani.nikula@intel.com

2019-11-30drm/panel: simple: Add Logic PD Type 28 display supportAdam Ford
Previously, there was an omap panel-dpi driver that would read generic timings from the device tree and set the display timing accordingly. This driver was removed so the screen no longer functions. This patch modifies the panel-simple file to setup the timings to the same values previously used.

2019-11-29drm: Inline drm_color_lut_extract()Ville Syrjälä
This thing can get called several thousand times per LUT so seems like we want to inline it to: - avoid the function call overhead - allow constant folding A quick synthetic test (w/o any hardware interaction) with a ridiculously large LUT size shows about 50% reduction in runtime on my HSW and BSW boxes. Slightly less with more reasonable LUT size but still easily measurable in tens of microseconds. v2: Include drm_color_mgmt.h in the .rst (Daniel) Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191108135654.12907-1-ville.syrjala@linux.intel.com

2019-11-29drm/edid: Add alternate clock for SMPTE 4KWayne Lin
[Why] In hdmi_mode_alternate_clock(), it adds an exception for VIC 4 mode (4096x2160@24) due to there is no alternate clock defined for that mode in HDMI1.4b. But HDMI2.0 adds 23.98Hz for that mode. [How] Remove the exception v2: Adjust the comment description of hdmi_mode_alternate_clock() due to there is no more exception for VIC 4 mode.

2019-11-29drm/edid: Add aspect ratios to HDMI 4K modesWayne Lin
[Why] HDMI 2.0 adds aspect ratio attribute to distinguish different 4k modes. According to Appendix E of HDMI 2.0 spec, source should use VSIF to indicate video mode only when the mode is one defined in HDMI 1.4b 4K modes. Otherwise, use AVI infoframes to convey VIC. Current code doesn't take aspect ratio into consideration while constructing avi infoframe. Should modify that. [How] Inherit Ville Syrjälä's work "drm/edid: Prep for HDMI VIC aspect ratio" at https://patchwork.kernel.org/patch/11174639/ Add picture_aspect_ratio attributes to edid_4k_modes[] and construct VIC and HDMI_VIC by taking aspect ratio into consideration. v2: Correct missing initializer error at adding aspect ratio of SMPTE mode.

2019-11-29drm/qxl: Complete exception handling in qxl_device_init()Markus Elfring
A coccicheck run provided information like the following. drivers/gpu/drm/qxl/qxl_kms.c:295:1-7: ERROR: missing iounmap; ioremap on line 178 and execution via conditional on line 185 Generated by: scripts/coccinelle/free/iounmap.cocci A jump target was specified in an if branch. The corresponding function call did not release the desired system resource then. Thus use the label “rom_unmap” instead to fix the exception handling for this function implementation.
