Mark reports that brightness is not restored after Xorg dpms screen blank. This behavior was introduced by commit d9e865826c20 ("drm/amd/display: Simplify brightness initialization") which dropped the cached backlight value in display code, but also removed code for when the default value read back was less than 1 nit.

2023-12-07drm/i915: Use internal class when counting engine resetsTvrtko Ursulin
Commit 503579448db9 ("drm/i915/gsc: Mark internal GSC engine with reserved uabi class") made the GSC0 engine not have a valid uabi class and so broke the engine reset counting, which in turn was made class based in cb823ed9915b ("drm/i915/gt: Use intel_gt as the primary object for handling resets"). Despite the title and commit text of the latter is not mentioning it (and has left the storage array incorrectly sized), tracking by class, despite it adding aliasing in hypthotetical multi-tile systems, is handy for virtual engines which for instance do not have a valid engine->id. Therefore we keep that but just change it to use the internal class which is always valid. We also add a helper to increment the count, which aligns with the existing getter. What was broken without this fix were out of bounds reads every time a reset would happen on the GSC0 engine, or during selftests when storing and cross-checking the counts in igt_live_test_begin and igt_live_test_end.

2023-12-07drm/i915: handle uncore spinlock when not availableLuca Coelho
The uncore code may not always be available (e.g. when we build the display code with Xe), so we can't always rely on having the uncore's spinlock. To handle this, split the spin_lock/unlock_irqsave/restore() into spin_lock/unlock() followed by a call to local_irq_save/restore() and create wrapper functions for locking and unlocking the uncore's spinlock. In these functions, we have a condition check and only actually try to lock/unlock the spinlock when I915 is defined, and thus uncore is available. This keeps the ifdefs contained in these new functions and all such logic inside the display code.

2023-12-07drm/mipi-dsi: Fix detach call without attachTomi Valkeinen
It's been reported that DSI host driver's detach can be called without the attach ever happening: https://lore.kernel.org/all/20230412073954.20601-1-tony@atomide.com/ After reading the code, I think this is what happens: We have a DSI host defined in the device tree and a DSI peripheral under that host (i.e. an i2c device using the DSI as data bus doesn't exhibit this behavior). The host driver calls mipi_dsi_host_register(), which causes (via a few functions) mipi_dsi_device_add() to be called for the DSI peripheral. So now we have a DSI device under the host, but attach hasn't been called. Normally the probing of the devices continues, and eventually the DSI peripheral's driver will call mipi_dsi_attach(), attaching the peripheral. However, if the host driver's probe encounters an error after calling mipi_dsi_host_register(), and before the peripheral has called mipi_dsi_attach(), the host driver will do cleanups and return an error from its probe function. The cleanups include calling mipi_dsi_host_unregister(). mipi_dsi_host_unregister() will call two functions for all its DSI peripheral devices: mipi_dsi_detach() and mipi_dsi_device_unregister(). The latter makes sense, as the device exists, but the former may be wrong as attach has not necessarily been done. To fix this, track the attached state of the peripheral, and only detach from mipi_dsi_host_unregister() if the peripheral was attached. Note that I have only tested this with a board with an i2c DSI peripheral, not with a "pure" DSI peripheral. However, slightly related, the unregister machinery still seems broken. E.g. if the DSI host driver is unbound, it'll detach and unregister the DSI peripherals. After that, when the DSI peripheral driver unbound it'll call detach either directly or using the devm variant, leading to a crash. And probably the driver will crash if it happens, for some reason, to try to send a message via the DSI bus. But that's another topic. Tested-by: H.

2023-12-07drm/exynos: fix a wrong error checkingInki Dae
Fix a wrong error checking in exynos_drm_dma.c module. In the exynos_drm_register_dma function, both arm_iommu_create_mapping() and iommu_get_domain_for_dev() functions are expected to return NULL as an error. However, the error checking is performed using the statement if(IS_ERR(mapping)), which doesn't provide a suitable error value. So check if 'mapping' is NULL, and if it is, return -ENODEV.
