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:

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.

Jani Nikula authored
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:

The connector->override_edid flag is strictly for EDID override debugfs management, and drivers have no business using it. The check for override_edid was added in commit 30190629 ("drm/i915: Ignore TMDS clock limit for DP++ when EDID override is set") to facilitate mode list cross-checking against modes in override EDID when the connector in question isn't even connected. The dual mode detect fallback would do VBT based limiting in this case. Instead of override EDID, check for connector forcing in the fallback. v2: Simply use !connector->force (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Jani Nikula authored
For normal connector detect, there's really no point in trying dual mode detect if the connector is disconnected. We can simplify the detect sequence by skipping it. Since intel_hdmi_dp_dual_mode_detect() is only called when EDID is present, we can drop the has_edid parameter. The functional effect is speeding up disconnected connector detection ever so slightly, and, combined with firmware EDID, also stop logging about assuming dual mode adaptor. It's a bit subtle, but this will also skip dual mode detect if the connector is force connected and a) there's no EDID of any kind, normal or override/firmware or b) there's EDID but it does not indicate digital. These are corner cases no matter what, and arguably forcing should not be limited by dual mode detect. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

It's important to get the initial size of cotables right because otherwise every app needs to start with a synchronous cotable resize. This has an measurable impact on system wide performance but is not relevant for long running single full screen apps for which the cotable resizes will happen early in the lifecycle and will continue running just fine. To eliminate the initial cotable resizes match the initial sizes to what the userspace expects. The actual result of the patch is simply setting the initial size of two of the cotables to a size that will align them to two pages instead of one. For a piglit run, before: name | total | per frame | per sec vmw_cotable_resize | 1405 | 0.12 | 1.58 vmw_execbuf_ioctl | 290805 | 25.43 | 326.05 After: name | total | per frame | per sec vmw_cotable_resize | 4 | 0.00 | 0.00 vmw_execbuf_ioctl | 281673 | 25.10 | 274.68 Signed-off-by:

The explicit vblank handling was never finished. The driver never had the full implementation of vblank and what was there is emulated by DRM when the driver doesn't pretend to be implementing it itself. Let DRM handle the vblank emulation and stop pretending the driver is doing anything special with vblank. In the future it would make sense to implement helpers for full vblank handling because vkms and amdgpu_vkms already have that code. Exporting it to common helpers and having all three drivers share it would make sense (that would be largely just to allow more of igt to run). Signed-off-by:

Instead of using vmwgfx specific framebuffer implementation use the drm fb helpers. There's no change in functionality, the only difference is a reduction in the amount of code inside the vmwgfx module. drm fb helpers do not deal correctly with changes in crtc preferred mode at runtime, but the old fb code wasn't dealing with it either. Same situation applies to high-res fb consoles - the old code was limited to 1176x885 because it was checking for legacy/deprecated memory limites, the drm fb helpers are limited to the initial resolution set on fb due to first problem (drm fb helpers being unable to handle hotplug crtc preferred mode changes). This also removes the kernel config for disabling fb support which hasn't been used or supported in a very long time. Signed-off-by:
