2021-07-28drm: Return -ENOTTY for non-drm ioctlsCharles Baylis
commit 3abab27c322e0f2acf981595aa8040c9164dc9fb upstream. drm: Return -ENOTTY for non-drm ioctls Return -ENOTTY from drm_ioctl() when userspace passes in a cmd number which doesn't relate to the drm subsystem. Glibc uses the TCGETS ioctl to implement isatty(), and without this change isatty() returns it incorrectly returns true for drm devices. To test run this command: $ if [ -t 0 ]; then echo is a tty; fi < /dev/dri/card0 which shows "is a tty" without this patch. This may also modify memory which the userspace application is not expecting.

2020-08-11drm/drm_fb_helper: fix fbdev with sparc64Sam Ravnborg
[ Upstream commit 2a1658bf922ffd9b7907e270a7d9cdc9643fc45d ] Recent kernels have been reported to panic using the bochs_drm framebuffer under qemu-system-sparc64 which was bisected to commit 7a0483ac4ffc ("drm/bochs: switch to generic drm fbdev emulation"). The backtrace indicates that the shadow framebuffer copy in drm_fb_helper_dirty_blit_real() is trying to access the real framebuffer using a virtual address rather than use an IO access typically implemented using a physical (ASI_PHYS) access on SPARC. The fix is to replace the memcpy with memcpy_toio() from io.h. memcpy_toio() uses writeb() where the original fbdev code used sbus_memcpy_toio(). The latter uses sbus_writeb(). The difference between writeb() and sbus_memcpy_toio() is that writeb() writes bytes in little-endian, where sbus_writeb() writes bytes in big-endian. As endian does not matter for byte writes they are the same. So we can safely use memcpy_toio() here. Note that this only fixes bochs, in general fbdev helpers still have issues with mixing up system memory and __iomem space. Fixing that will require a lot more work. v3: - Improved changelog (Daniel) - Added FIXME to fbdev_use_iomem (Daniel) v2: - Added missing __iomem cast (kernel test robot) - Made changelog readable and fix typos (Mark) - Add flag to select iomem - and set it in the bochs driver Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reported-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Reported-by: kernel test robot <lkp@intel.com> Tested-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: "David S.

2020-05-10drm/bridge: analogix_dp: Split bind() into probe() and real bind()Marek Szyprowski
[ Upstream commit 83a196773b8bc6702f49df1eddc848180e350340 ] Analogix_dp driver acquires all its resources in the ->bind() callback, what is a bit against the component driver based approach, where the driver initialization is split into a probe(), where all resources are gathered, and a bind(), where all objects are created and a compound driver is initialized. Extract all the resource related operations to analogix_dp_probe() and analogix_dp_remove(), then call them before/after registration of the device components from the main Exynos DP and Rockchip DP drivers. Also move the plat_data initialization to the probe() to make it available for the analogix_dp_probe() function. This fixes the multiple calls to the bind() of the DRM compound driver when the DP PHY driver is not yet loaded/probed: [drm] Exynos DRM: using 14400000.fimd device for DMA mapping operations exynos-drm exynos-drm: bound 14400000.fimd (ops fimd_component_ops [exynosdrm]) exynos-drm exynos-drm: bound 14450000.mixer (ops mixer_component_ops [exynosdrm]) exynos-dp 145b0000.dp-controller: no DP phy configured exynos-drm exynos-drm: failed to bind 145b0000.dp-controller (ops exynos_dp_ops [exynosdrm]): -517 exynos-drm exynos-drm: master bind failed: -517 ...

2020-02-13LF-794 gpu: cdn: imx8qm: Add firmware loading supportAbel Vesa
This allows the HDP i.MX8QM driver to load the firmware on init and resume. In order to have backward compatibility, if there is no firmware-name property defined in the hdmi node, the driver probing sequence skips the firmware loading. Also, if u-boot has loaded already a firmware, we run with that but when probing the driver, the request_firmware_nowait is used to locate and keep safe the firmware for when suspend/resume happens. This leads to 4 possible scenarios: 1. u-boot loads the firmware, the kernel driver finds the firmware when rootfs is mounted. This is the most desirable scenario. Also this is the only scenario that allows the hdmi to work after resume. 2. u-boot loads the firmware, the kernel driver _doesn't_ find the firmware in rootfs. If there is no suspend ever happening, the kernel driver will keep using the firmware that was loaded by u-boot. On the first suspend/resume, the firmware is lost because the HDMI IP gets powered down. 3. u-boot doesn't load the firmare, the kernel driver probing tries to load the firmware, assuming this is available (see CONFIG_EXTRA_FIRMWARE). 4. u-boot doesn't load the firmware and the kernel driver is not able to find it either. The probing fails and there is no HDMI available in linux. Signed-off-by: Abel Vesa <abel.vesa@nxp.com> Reviewed-by: Sandor Yu <sandor.yu@nxp.com>

So a general way is created to solve this problem which can provide an optimum solution to output a PLL bit clock to match the request frequency in a maximum degree and also satisfy the input clock and intermediate clocks limit according to the PLL specification.

2019-11-25MLK-19252-6 drm/bridge: sec-dsim: improve DPHY TIMING configsFancy Fang
The SEC provides a table to guide the DPHY TIMINGS config based on the PLL output bit clock frequency for DSIM. So create the table which is used by SEC LN14LPP DPHY with HS Timing v1.2 and this table will be used by the SEC DSIM Bridge driver to help to config the corresponding DPHY Timings correctly for each display mode. Along with the table, a DPHY TIMING table entry 'compare' method is implemented for the binary search when lookup the suitable DPHY TIMING entry.

Defer the PLL output check to the SEC DSIM Encoder's atomic check from SEC DSIM Bridge's mode_fixup(), since in the attached DSI device Bridge's mode_fixup(), it may change the data lanes number, and this change is done after the SEC DSIM Bridge's mode_fixup(). And the DSIM Encoder's atomic check is the ideal place to do this PLL check, since it happens after all the Bridges' mode_fixup() done.

2019-11-25MLK-16290 drm: Add drm_of_component_probe_with_match() helperLiu Ying
A component master may have both OF based and non-OF based components to be bound with. This patch adds a helper drm_of_component_probe_with_match() similar to drm_of_component_probe() so that the new helper may get an additional provided match pointer(contains match entries for non-OF based components) to support this case.

2019-11-06drm/atomic: fix self-refresh helpers crtc state dereferenceRob Clark
drm_self_refresh_helper_update_avg_times() was incorrectly accessing the new incoming state after drm_atomic_helper_commit_hw_done(). But this state might have already been superceeded by an !nonblock atomic update resulting in dereferencing an already free'd crtc_state. TODO I *think* this will more or less do the right thing.. althought I'm not 100% sure if, for example, we enter psr in a nonblock commit, and then leave psr in a !nonblock commit that overtakes the completion of the nonblock commit. Not sure if this sort of scenario can happen in practice. But not crashing is better than crashing, so I guess we should either take this patch or rever the self-refresh helpers until Sean can figure out a better solution.

2019-09-19drm: Measure Self Refresh Entry/Exit times to avoid thrashingSean Paul
Currently the self refresh idle timer is a const set by the crtc. This is fine if the self refresh entry/exit times are well-known for all panels used on that crtc. However panels and workloads can vary quite a bit, and a timeout which works well for one doesn't work well for another. In the extreme, if the timeout is too short we could get in a situation where the self refresh exits are taking so long we queue up a self refresh entry before the exit commit is even finished. This patch changes the idle timeout to a moving average of the entry times + a moving average of exit times + the crtc constant. This patch was tested on rockchip, with a kevin CrOS panel the idle delay averages out to about ~235ms (35 entry + 100 exit + 100 const). On the same board, the bob panel idle delay lands around ~340ms (90 entry + 150 exit + 100 const). WRT the dedicated mutex in self_refresh_data, it would be nice if we could rely on drm_crtc.mutex to protect the average times, but there are a few reasons why a separate lock is a better choice: - We can't rely on drm_crtc.mutex being held if we're doing a nonblocking commit - We can't grab drm_crtc.mutex since drm_modeset_lock() doesn't tell us whether the lock was already held in the acquire context (it eats -EALREADY), so we can't tell if we should drop it or not - We don't need such a heavy-handed lock for what we're trying to do, commit ordering doesn't matter, so a point-of-use lock will be less contentious Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link to v1: https://patchwork.freedesktop.org/patch/msgid/20190917200443.64481-2-sean@poorly.run Link: https://patchwork.freedesktop.org/patch/msgid/20190918200734.149876-2-sean@poorly.run Changes in v2: - Migrate locking explanation from comment to commit msg (Daniel) - Turf constant entry delay and multiply the avg times by 2 (Daniel)

It's the only flag anyone actually cares about. Plus if we're unlucky, the atomic ioctl might need a different flag for async flips. So better to abstract this away from the uapi a bit.
