2024-04-25drm/{i915, xe}: Implement fbdev emulation as in-kernel clientThomas Zimmermann
Replace all code that initializes or releases fbdev emulation throughout the driver. Instead initialize the fbdev client by a single call to intel_fbdev_setup() after i915 has registered its DRM device. Just like similar code in other drivers, i915 fbdev emulation now acts like a regular DRM client. Do the same for xe. The fbdev client setup consists of the initial preparation and the hot-plugging of the display. The latter creates the fbdev device and sets up the fbdev framebuffer. The setup performs display hot-plugging once. If no display can be detected, DRM probe helpers re-run the detection on each hotplug event. A call to drm_client_dev_unregister() releases all in-kernel clients automatically. No further action is required within i915. If the fbdev framebuffer has been fully set up, struct fb_ops.fb_destroy implements the release. For partially initialized emulation, the fbdev client reverts the initial setup. Do the same for xe and remove its call to intel_fbdev_fini(). v8: - setup client in intel_display_driver_register (Jouni) - mention xe in commit message v7: - update xe driver - reword commit message v6: - use 'i915' for i915 device (Jouni) - remove unnecessary code for non-atomic mode setting (Jouni, Ville) - fix function name in commit message (Jouni) v3: - as before, silently ignore devices without displays v2: - let drm_client_register() handle initial hotplug - fix driver name in error message (Jani) - fix non-fbdev build (kernel test robot) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jouni Högander <jouni.hogander@intel.com> Acked-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240409081029.17843-7-tzimmermann@suse.de Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2024-04-25drm/{i915,xe}: Implement fbdev client callbacksThomas Zimmermann
Move code from ad-hoc fbdev callbacks into DRM client functions and remove the old callbacks. The functions instruct the client to poll for changed output or restore the display. The DRM core calls both, the old callbacks and the new client helpers, from the same places. The new functions perform the same operation as before, so there's no change in functionality. Fox xe, remove xe_display_last_close(), which restored the fbdev display. As with i915, the DRM core's drm_lastclose() performs this operation automatically. v8: - mention xe in commit message v7: - update xe driver v6: - return errors from client callbacks (Jouni) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jouni Högander <jouni.hogander@intel.com> Acked-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240409081029.17843-6-tzimmermann@suse.de Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2024-04-25drm/{i915,xe}: Unregister in-kernel clientsThomas Zimmermann
Unregister all in-kernel clients before unloading the i915 driver. For other drivers, drm_dev_unregister() does this automatically. As i915 and xe do not use this helper, they have to perform the call by themselves. Note that there are currently no in-kernel clients in i915 or xe.

Most users of _MMIO_PIPE3() and _MMIO_PORT3() need to add the MMIO base to the registers. Convert the macros to _MMIO_BASE_PIPE3() and _MMIO_BASE_PORT3() to move the base addition until after the register selection. If the register address depends on DISPLAY_MMIO_BASE(), this removes the need to figure the base out for each register, and it only needs to be added once.

2024-04-24drm/i915: Fix gt reset with GuC submission is disabledNirmoy Das
Currently intel_gt_reset() kills the GuC and then resets requested engines. This is problematic because there is a dedicated CSB FIFO which only GuC can access and if that FIFO fills up, the hardware will block on the next context switch until there is space that means the system is effectively hung. If an engine is reset whilst actively executing a context, a CSB entry will be sent to say that the context has gone idle. Thus if reset happens on a very busy system then killing GuC before killing the engines will lead to deadlock because of filled up CSB FIFO. To address this issue, the GuC should be killed only after resetting the requested engines and before calling intel_gt_init_hw(). v2: Improve commit message(John) Cc: John Harrison <john.c.harrison@intel.com> Signed-off-by: Nirmoy Das <nirmoy.das@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Reviewed-by: Andi Shyti <andi.shyti@linux.intel.com> Signed-off-by: Andi Shyti <andi.shyti@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240422201951.633-2-nirmoy.das@intel.com

- Add tracking clear page feature. - Driver should enable the DRM_BUDDY_CLEARED flag if it successfully clears the blocks in the free path. On the otherhand, DRM buddy marks each block as cleared. - Track the available cleared pages size - If driver requests cleared memory we prefer cleared memory but fallback to uncleared if we can't find the cleared blocks. when driver requests uncleared memory we try to use uncleared but fallback to cleared memory if necessary. - When a block gets freed we clear it and mark the freed block as cleared, when there are buddies which are cleared as well we can merge them. Otherwise, we prefer to keep the blocks as separated. - Add a function to support defragmentation. v1: - Depends on the flag check DRM_BUDDY_CLEARED, enable the block as cleared. Else, reset the clear flag for each block in the list(Christian) - For merging the 2 cleared blocks compare as below, drm_buddy_is_clear(block) != drm_buddy_is_clear(buddy)(Christian) - Defragment the memory beginning from min_order till the required memory space is available. v2: (Matthew) - Add a wrapper drm_buddy_free_list_internal for the freeing of blocks operation within drm buddy. - Write a macro block_incompatible() to allocate the required blocks. - Update the xe driver for the drm_buddy_free_list change in arguments. - add a warning if the two blocks are incompatible on defragmentation - call full defragmentation in the fini() function - place a condition to test if min_order is equal to 0 - replace the list with safe_reverse() variant as we might remove the block from the list. v3: - fix Gitlab user reported lockup issue. - Keep DRM_BUDDY_HEADER_CLEAR define sorted(Matthew) - modify to pass the root order instead max_order in fini() function(Matthew) - change bool 1 to true(Matthew) - add check if min_block_size is power of 2(Matthew) - modify the min_block_size datatype to u64(Matthew) v4: - rename the function drm_buddy_defrag with __force_merge. - Include __force_merge directly in drm buddy file and remove the defrag use in amdgpu driver. - Remove list_empty() check(Matthew) - Remove unnecessary space, headers and placement of new variables(Matthew) - Add a unit test case(Matthew) v5: - remove force merge support to actual range allocation and not to bail out when contains && split(Matthew) - add range support to force merge function. v6: - modify the alloc_range() function clear page non merged blocks allocation(Matthew) - correct the list_insert function name(Matthew).

2024-04-19drm/i915/dp_mst: Enable HBLANK expansion quirk for UHBR ratesImre Deak
Enabling the 5k@60Hz uncompressed mode on the MediaTek/Dell U3224KBA monitor results in a blank screen, at least on MTL platforms on UHBR link rates with some (<30) uncompressed bpp values. Enabling compression fixes the problem, so do that for now. Windows enables DSC always if the sink supports it and forcing it to enable the mode without compression leads to the same problem above (which suggests a panel issue with uncompressed mode). The same 5k mode on non-UHBR link rates is not affected and lower resolution modes are not affected either. The problem is similar to the one fixed by the HBLANK expansion quirk on Synaptics hubs, with the difference that the problematic mode has a longer HBLANK duration. Also the monitor doesn't report supporting HBLANK expansion; either its internal MST hub does the expansion internally - similarly to the Synaptics hub - or the issue has another root cause, but still related to the mode's short HBLANK duration. Enable the quirk for the monitor adjusting the detection for the above differences. v2: Rebase on drm_dp_128132b_supported() change.

However based on testing various 5k/6k modes both on the DELL U3224KBA monitor and the Unigraf UCD-500 CTS test device, both the channel coding efficiency (which includes the FEC overhead) and an additional 3% overhead must be accounted for to get these modes working.

2024-04-19drm/i915/dp_mst: Fix symbol clock when calculating the DSC DPT bpp limitImre Deak
The expected link symbol clock unit when calculating the DSC DPT bpp limit is kSymbols/sec, aligning with the dotclock's kPixels/sec unit based on the crtc clock. As opposed to this port_clock is used - which has a 10 kbits/sec unit - with the resulting symbol clock in 10 kSymbols/sec units (disregarding the rounding error for the 13.5Gbps rate). Fix the calculation using the expected 10x factor.

2024-04-19drm/i915/dp: Fix DSC line buffer depth programmingImre Deak
Fix the calculation of the DSC line buffer depth. This is limited both by the source's and sink's maximum line buffer depth, but the former one was not taken into account. On all Intel platform's the source's maximum buffer depth is 13, so the overall limit is simply the minimum of the source/sink's limit, regardless of the DSC version. This leaves the DSI DSC line buffer depth calculation as-is, trusting VBT. On DSC version 1.2 for sinks reporting a maximum line buffer depth of 16 the line buffer depth was incorrectly programmed as 0, leading to a corruption in color gradients / lines on the decompressed screen image.

2024-04-19drm/i915/display: force qgv check after the hw state readoutVinod Govindapillai
The current intel_bw_atomic_check do not check the possbility of a sagv configuration change after the hw state readout. Hence cannot update the sagv configuration until some other relevant changes like data rates, number of planes etc. happen. Introduce a flag to force qgv check in such cases.

2024-04-19drm/i915/display: handle systems with duplicate psf gv pointsStanislav Lisovskiy
There could be multiple qgv and psf gv points with similar values. Apparently pcode's handling of psf and qgv points are different. For qgv case, pcode sets whatever is asked by the driver. But in case of psf gv points, it compares the bw from points before setting the mask. This can cause problems in scenarios where we have to disable sagv by setting the highest bw point and there could be multiple points with highest bw. So to set the maximum psf gv point, find out all the points with the highest bw and set all together. v1: - use the same treatment to qgv points as well (Vinod) v2: - pcode confirms that for qgv points, it sets whatever the driver sets (Vinod) Reviewed-by: Jouni Högander <jouni.hogander@intel.com> Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Signed-off-by: Vinod Govindapillai <vinod.govindapillai@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240405113533.338553-6-vinod.govindapillai@intel.com
