This used to be ignored silently. Set the fwnode mipi_dsi_device so fw_devlink can find them and properly track their dependencies.

2023-05-03drm/i915/guc: Fix error capture for virtual enginesJohn Harrison4-7/+70
GuC based register dumps in error capture logs were basically broken for virtual engines. This can be seen in igt@gem_exec_balancer@hang: [IGT] gem_exec_balancer: starting subtest hang [drm] GPU HANG: ecode 12:4:e1524110, in gem_exec_balanc [6388] [drm] GT0: GUC: No register capture node found for 0x1005 / 0xFEDC311D [drm] GPU HANG: ecode 12:4:00000000, in gem_exec_balanc [6388] [IGT] gem_exec_balancer: exiting, ret=0 The test causes a hang on both engines of a virtual engine context. The engine instance zero hang gets a valid error capture but the non-instance-zero hang does not. Fix that by scanning through the list of pending register captures when a hang notification for a virtual engine is received. That way, the hang can be assigned to the correct physical engine prior to starting the error capture process. So later on, when the error capture handler tries to find the engine register list, it looks for one on the correct engine. Also, sneak in a missing blank line before a comment in the node search code. v2: Fix null pointer deref on non-GuC platforms.

2023-05-03drm/i915/dsi: Use unconditional msleep() instead of intel_dsi_msleep()Hans de Goede4-30/+6
The intel_dsi_msleep() helper skips sleeping if the MIPI-sequences have a version of 3 or newer and the panel is in vid-mode. This is based on the big comment around line 730 which starts with "Panel enable/disable sequences from the VBT spec.", where the "v3 video mode seq" column does not have any wait t# entries. Checking the Windows driver shows that it does always honor the VBT delays independent of the version of the VBT sequences. Commit 6fdb335f1c9c ("drm/i915/dsi: Use unconditional msleep for the panel_on_delay when there is no reset-deassert MIPI-sequence") switched to a direct msleep() instead of intel_dsi_msleep() when there is no MIPI_SEQ_DEASSERT_RESET sequence, to fix the panel on an Acer Aspire Switch 10 E SW3-016 not turning on. And now testing on a Nextbook Ares 8A shows that panel_on_delay must always be honored otherwise the panel will not turn on. Instead of only always using regular msleep() for panel_on_delay do as Windows does and always use regular msleep() everywhere were intel_dsi_msleep() is used and drop the intel_dsi_msleep() helper.

2023-05-03drm/i915/guc: Actually return an error if GuC version range check failsJohn Harrison1-8/+12
Dan Carpenter pointed out that 'err' was not being set in the case where the GuC firmware version range check fails. Fix that. Note that while this is a bug fix for a previous patch (see Fixes tag below). It is an exceedingly low risk bug. The range check is asserting that the GuC firmware version is within spec. So it should not be possible to ever have a firmware file that fails this check. If larger version numbers are required in the future, that would be a backwards breaking spec change and thus require a major version bump, in which case an old i915 driver would not load that new version anyway.

2023-05-02i915/pmu: Add support for total context runtime for GuC back-endUmesh Nerlige Ramappa4-2/+38
GPU accumulates the context runtime in a 32 bit counter - CTX_TIMESTAMP in the context image. This value is saved/restored on context switches. KMD accumulates these values into a 64 bit counter taking care of any overflows as needed. This count provides the basis for client specific busyness in the fdinfo interface. KMD accumulation happens just before the context is unpinned and when context switches out. This works for execlist back-end since execlist scheduling has visibility into context switches. With GuC mode, KMD does not have visibility into context switches and this counter is accumulated only when context is unpinned. Context is unpinned once the context scheduling is successfully disabled. Disabling context scheduling is an asynchronous operation. Also if a context is servicing frequent requests, scheduling may never be disabled on it. For GuC mode, since updates to the context runtime may be delayed, add hooks to update the context runtime in a worker thread as well as when a user queries for it. Limitation: - If a context is never switched out or runs for a long period of time, the runtime value of CTX_TIMESTAMP may never be updated, so the counter value may be unreliable. This patch does not support such cases. Such support must be available from the GuC FW and it is WIP.
