With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG), indirect call targets are validated against the expected function pointer prototype to make sure the call target is valid to help mitigate ROP attacks. If they are not identical, there is a failure at run time, which manifests as either a kernel panic or thread getting killed. A proposed warning in clang aims to catch these at compile time, which reveals: drivers/gpu/drm/meson/meson_encoder_cvbs.c:211:16: error: incompatible function pointer types initializing 'enum drm_mode_status (*)(struct drm_bridge *, const struct drm_display_info *, const struct drm_display_mode *)' with an expression of type 'int (struct drm_bridge *, const struct drm_display_info *, const struct drm_display_mode *)' [-Werror,-Wincompatible-function-pointer-types-strict] .mode_valid = meson_encoder_cvbs_mode_valid, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 error generated. ->mode_valid() in 'struct drm_bridge_funcs' expects a return type of 'enum drm_mode_status', not 'int'. Adjust the return type of meson_encoder_cvbs_mode_valid() to match the prototype's to resolve the warning and CFI failure. Link: https://github.com/ClangBuiltLinux/linux/issues/1750Reported-by:

Cursor snooping depended on implicit size and format which made debugging quite difficult. Make the code easier to following by making everything explicit and instead of using magic numbers predefine all the parameters the code depends on. Also fixes incorrectly computed pitches for non-aligned cursor snoops. Fix which has no practical effect because non-aligned cursor snoops are not used by the X11 driver and Wayland cursors will go through mob cursors, instead of surface dma's. Signed-off-by:

Esmart0-win0 could serve as primary plane, so mark it as such. On RK3568 this window will never be used as primary plane, because the three windows at the beginning of the rk3568_vop_win_data[] array will be used. On RK3566 however, two of the windows at the beginning of the rk3568_vop_win_data[] array cannot not be used due to hardware limitations, so without this patch we end up with CRTCs without primary planes when multiple VPs are active.

adv7511 probe may need to be attempted multiple times before no -EPROBE_DEFER is returned. Currently, every such probe results in an error message: [ 4.534229] adv7511 1-003d: failed to find dsi host [ 4.580288] adv7511 1-003d: failed to find dsi host This is misleading, as there is no error and probe deferral is normal behavior. Fix this by using dev_err_probe that will suppress -EPROBE_DEFER errors. While at it, we touch all dev_err in the probe path. This makes the code more concise and included the error code everywhere to aid user in debugging. Reviewed-by:

Following the clock rate range improvements to the clock framework, trying to set a disjoint range on a clock will now result in an error. Thus, we can't set a minimum rate higher than the maximum reported by the firmware, or clk_set_min_rate() will fail. Thus we need to clamp the rate we are about to ask for to the maximum rate possible on that clock. Reviewed-by:

In order to support higher HDMI frequencies, users have to set the hdmi_enable_4kp60 parameter in their config.txt file. This will have the side-effect of raising the maximum of the core clock, tied to the HVS, and managed by the HVS driver. However, we are querying this in the HDMI driver by poking into the HVS structure to get our struct clk handle. Let's make this part of the HVS bind implementation to have all the core clock related setup in the same place. Reviewed-by:

Maxime Ripard authored
In order to support higher HDMI frequencies, users have to set the hdmi_enable_4kp60 parameter in their config.txt file. We were detecting this so far by calling clk_round_rate() on the core clock with the frequency we're supposed to run at when one of those modes is enabled. Whether or not the parameter was enabled could then be inferred by the returned rate since the maximum clock rate reported by the firmware was one of the side effect of setting that parameter. However, the recent clock rework we did changed what clk_round_rate() was returning to always return the minimum allowed, and thus this test wasn't reliable anymore. Let's use the new clk_get_max_rate() function to reliably determine the maximum rate allowed on that clock and fix the 4k@60Hz output.

There's a lot going on here, but the main thing is switching the firmware EDID loader to use struct drm_edid. Unfortunately, it's difficult to reasonably split to smaller pieces. Convert the EDID loader to struct drm_edid. There's a functional change in validation; it no longer tries to fix errors or filter invalid blocks. It's stricter in this sense. Hopefully this will not be an issue. As a by-product, this change also allows HF-EEODB extended EDIDs to be passed via override/firmware EDID. Signed-off-by:

Having the EDID override debugfs directly update the EDID property is problematic. The update is partial only. The driver has no way of knowing it's been updated. Mode list is not updated. It's an inconsistent state. Detach debugfs EDID override from the property update completely. Only set and reset a separate override EDID copy from debugfs, and have it take effect only at detect (via EDID read). The copy is at connector->edid_override, protected by connector->edid_override_mutex. This also brings override EDID closer to firmware EDID in behaviour. Add validation of the override EDID which we completely lacked. Note that IGT already forces a detect whenever tests update the override EDID. v2: Add locking (Ville) Signed-off-by:
