2022-04-19drm/i915/display/psr: Clear more PSR state during disableJosé Roberto de Souza
After commit 805f04d42a6b ("drm/i915/display/psr: Use continuos full frame to handle frontbuffer invalidations") was merged we started to get some drm_WARN_ON(&dev_priv->drm, !(tmp & PSR2_MAN_TRK_CTL_ENABLE)) in tests that are executed in pipe B. This is probably due psr2_sel_fetch_cff_enabled being left set during PSR disable in the pipe A, so the PSR2_MAN_TRK_CTL write in intel_psr2_program_trans_man_trk_ctl() is skipped in pipe B and then we get the warning when actually enabling PSR after planes programing. We don't get such warnings when running tests in pipe A because PSR2_MAN_TRK_CTL is only cleared when enabling PSR2 with hardware tracking. Was not able to reproduce this issue but cleaning the PSR state disable will not harm anything at all.

intel_psr2_config_valid() fails If any of the PSR2 checks after intel_psr2_sel_fetch_config_valid() fails, enable_psr2_sel_fetch will be kept enabled causing problems in the functions that only checks for it and not for has_psr2. So here moving the check that do not depend on enable_psr2_sel_fetch and for the remaning ones jumping to a section that unset enable_psr2_sel_fetch in case of failure to support PSR2.

2022-04-14drm/i915/guc: Update to GuC version 70.1.1John Harrison
The latest GuC firmware drops the context descriptor pool in favour of passing all creation data in the create H2G. It also greatly simplifies the work queue and removes the process descriptor used for multi-LRC submission. So, remove all mention of LRC and process descriptors and update the registration code accordingly. Unfortunately, the new API also removes the ability to set default values for the scheduling policies at context registration time. Instead, a follow up H2G must be sent. The individual scheduling policy update H2G commands are also dropped in favour of a single KLV based H2G. So, change the update wrappers accordingly and call this during context registration.. Of course, this second H2G per registration might fail due to being backed up. The registration code has a complicated state machine to cope with the actual registration call failing. However, if that works then there is no support for unwinding if a further call should fail. Unwinding would require sending a H2G to de-register - but that can't be done because the CTB is already backed up. So instead, add a new flag to say whether the context has a pending policy update. This is set if the policy H2G fails at registration time. The submission code checks for this flag and retries the policy update if set. If that call fails, the submission path early exists with a retry error. This is something that is already supported for other reasons.

2022-04-14drm/i915/migrate: Evict and restore the flatccs capable lmem objRamalingam C
When we are swapping out the local memory obj on flat-ccs capable platform, we need to capture the ccs data too along with main meory and we need to restore it when we are swapping in the content. When lmem object is swapped into a smem obj, smem obj will have the extra pages required to hold the ccs data corresponding to the lmem main memory. So main memory of lmem will be copied into the initial pages of the smem and then ccs data corresponding to the main memory will be copied to the subsequent pages of smem. ccs data is 1/256 of lmem size. Swapin happens exactly in reverse order. First main memory of lmem is restored from the smem's initial pages and the ccs data will be restored from the subsequent pages of smem.

2022-04-14drm/i915/gem: Add extra pages in ttm_tt for ccs dataRamalingam C
On Xe-HP and later devices, dedicated compression control state (CCS) stored in local memory is used for each surface, to support the 3D and media compression formats. The memory required for the CCS of the entire local memory is 1/256 of the local memory size. So before the kernel boot, the required memory is reserved for the CCS data and a secure register will be programmed with the CCS base address So when an object is allocated in local memory, dont need to explicitly allocate the space for ccs data. But when the obj is evicted into the smem, to hold the compression related data along with the obj extra space is needed in smem. i.e obj_size + (obj_size/256).

2022-04-13fbcon: Fix delayed takeover lockingDaniel Vetter
I messed up the delayed takover path in the locking conversion in 6e7da3af008b ("fbcon: Move console_lock for register/unlink/unregister"). If CONFIG_FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER is enabled, fbcon take-over doesn't take place when calling fbcon_fb_registered(). Instead, is deferred using a workqueue and its fbcon_register_existing_fbs() function calls to fbcon_fb_registered() again for each registered fbcon fb. This leads to the console_lock tried to be held twice, causing a deadlock. Fix it by re-extracting the lockless function and using it in the delayed takeover path, where we need to hold the lock already to iterate over the list of already registered fb. Well the current code still is broken in there (since the list is protected by a registration_lock, which we can't take here because it nests the other way round with console_lock), but in the future this will be a list protected by console_lock when this is all sorted out. While reviewing the broken commit I realized that I've left some outdated comments about the locking behind. Fix those too. v2: Improve commit message (Javier) Reported-by: Nathan Chancellor <nathan@kernel.org> Tested-by: Nathan Chancellor <nathan@kernel.org> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Cc: Nathan Chancellor <nathan@kernel.org> Fixes: 6e7da3af008b ("fbcon: Move console_lock for register/unlink/unregister") Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Du Cheng <ducheng2@gmail.com> Cc: Claudio Suarez <cssk@net-c.es> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> Cc: Matthew Wilcox <willy@infradead.org> Cc: Zheyu Ma <zheyuma97@gmail.com> Cc: Guenter Roeck <linux@roeck-us.net> Cc: Helge Deller <deller@gmx.de> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Javier Martinez Canillas <javierm@redhat.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220413082128.348186-1-daniel.vetter@ffwll.ch
2022-04-13drm/panel: lvds: Use bus_flags from DT panel-timing propertyMarek Vasut
This driver currently rewrites bus_flags based solely on the value of DT property 'data-mirror' and ignores bus_flags which might have been set in DT panel-timing node. Specificaly, the 'de-active' DT property sets DRM_BUS_FLAG_DE_ bus_flags. Since of_get_drm_panel_display_mode() conveniently parses the bus_flags out of DT panel-timing property, just ORR them with bus_flags inferred from 'data-mirror' DT property and use the result as panel bus_flags. This fixes handling of panels with 'panel-timing { de-active = <1>; };'.

2022-04-13drm/panel: lvds: Simplify mode parsingMarek Vasut
The mode parsing is currently implemented in three steps: of_get_display_timing() - DT panel-timing to struct display_timing videomode_from_timing() - struct display_timing to struct videomode drm_display_mode_from_videomode() - struct videomode to struct drm_display_mode Replace all that with simple of_get_drm_panel_display_mode() call, which already populates struct drm_display_mode and then duplicate that mode in panel_lvds_get_modes() each time, since the mode does not change. Nice bonus is the bus_flags parsed by of_get_drm_panel_display_mode() out of panel-timing DT node, which is used in subsequent patch to fix handling of 'de-active' DT property.

2022-04-13drm: bridge: icn6211: Convert to regmapMarek Vasut
To make debugging easier, convert driver to regmap. Implement read and write regmap tables for known registers, keep all known register readable and mark those which are obviously read-only as not writeable. Use common I2C regmap for the I2C configuration, implement custom regmap bus for DSI configuration. The later is mandatory as this chip requires one extra byte set to read access length between register address and data.

Let's make sure FBC is always disabled when we start to take over the hardware state. I suspect this should never really happen, since the only time when we really should be taking over with the display already active is when the previous state was progammed by the BIOS, which likely shouldn't use FBC. This could be driver init, or S4 resume when the boot kernel doesn't load i915. But I suppose no harm in keeping this code around for exra safety since it's quite trivial.
