It technically loads, and runs, but is ultimately pointless outside of a very narrow window (fanless systems where one wants to attempt using the, broken for a lot of gm20x, memory reclocking code). It's also potentially dangerous to override the VBIOS-provided "Pre-OS" PMU, which would be responsible for fan control otherwise. Signed-off-by: -

This will prevent some pain with broken firmware trees, as under some circumstances the HSFW can fail and leave the GPU in a state we don't know how to recover from. Signed-off-by: -

This will prevent reloading of HS FW where it's pointless, and bypass hitting some timeouts. Not a situation one should generally hit, but can occur with a messed up firmware installation. Signed-off-by: -

This is less than useful with some subdevs having _nofw variants in their FWIF lists - it's cleaner to handle them all in the same way. Signed-off-by: -

This causes us to invalidate MMU only at the level we made modifications - ie: if we've only modified PTEs, there's no need to have MMU dump the PDs it's fetched into L2. Signed-off-by: -

Rename all structures that are used directly by firmware to have a nvfw_ prefix. This makes it easier to identify structures that have a fixed, specific layout. A future patch will define several more such structures, so it's important to be consistent now. Signed-off-by:

nvkm_timer_wait_init() takes a u64 as a duration parameter, but the expression "(m) * 1000" will be promoted only to a 32-bit integer, if 'm' is also an integer. Changing the 1000 to 1000ULL ensures that the expression will be 64 bits. This change currently has no effect as there are no callers of nvkm_msec() that exceed 2000ms. Signed-off-by:

drm/tegra: Changes for v5.9-rc1 This set of patches contains a few preparatory patches to enable video capture support from external camera modules. This is a dependency for the V4L2 driver patches that will likely be merged in v5.9 or v5.10. On top of that there are a couple of fixes across the board as well as some improvements. From a feature point of view this also adds support for horizontal reflection and 180° rotation of planes. Signed-off-by:

drm/imx: error path fixes and cleanups - Fix use after free issue in component bind error path by keeping memory allocated as long as the driver is bound. This will be replaced with drm managed memory in the next round. - Fix bus_flags overriding logic in parallel-display. - Disable regulator in imx-tve bind error path. - Drop unnecessary best_encoder callback. - Remove an unused enum in imx-ldb. - Bail out early on missing panel or bridge in parallel-display to speed up -EPROBE_DEFER path. - Disable both LDB channels in split mode. - Restore RGB32, BGR32 format support. - Fix tiled image conversion in case of out of order interrupts. - Remove a superfluous error message in imx-tve.

The sparse tool complains as follows: drivers/dma-buf/dma-fence.c:249:25: warning: symbol 'dma_fence_lockdep_map' was not declared. Should it be static? This variable is not used outside of dma-fence.c, so this commit marks it static. Fixes: 5fbff813 ("dma-fence: basic lockdep annotations") Reported-by:

drm-misc-next for v5.9: UAPI Changes: Cross-subsystem Changes: - Convert panel-dsi-cm and ingenic bindings to YAML. - Add lockdep annotations for dma-fence. \o/ - Describe why indefinite fences are a bad idea - Update binding for rocktech jh057n00900. Core Changes: - Add vblank workers. - Use spin_(un)lock_irq instead of the irqsave/restore variants in crtc code. - Add managed vram helpers. - Convert more logging to drm functions. - Replace more http links with https in core and drivers. - Cleanup to ttm iomem functions and implementation. - Remove TTM CMA memtype as it doesn't work correctly. - Remove TTM_MEMTYPE_FLAG_MAPPABLE for many drivers that have no unmappable memory resources. Driver Changes: - Add CRC support to nouveau, using the new vblank workers. - Dithering and atomic state fix for nouveau. - Fixes for Frida FRD350H54004 panel. - Add support for OSD mode (sprite planes), IPU (scaling) and multiple panels/bridges to ingenic. - Use managed vram helpers in ast. - Assorted small fixes to ingenic, i810, mxsfb. - Remove optional unused ttm dummy functions.

This is an ioctl callback, so we're guaranteed to have IRQs enabled when calling this function. Use the plain _irq() variants of spin_(un)lock() to make this more obvious. Signed-off-by:

This one's easy - we're already calling kzalloc(GFP_KERNEL) in this function, so we must already be guaranteed to have IRQs enabled when calling this. So, use the plain _irq() variants of spin_(un)lock() to make this more obvious. Signed-off-by:

This function is only ever called from ioctl context, so we're guaranteed to have interrupts enabled. Stop using the irqsave/irqrestore variants of spin_(un)lock_irq() to make this more obvious. Signed-off-by:

This is only called from: * Atomic modesetting hooks * Module probing routines * Legacy modesetting hooks All of which have IRQs enabled, so we can also get rid of irqsave/restore here to make the IRQ context of this function more obvious. Signed-off-by:

Lyude Paul authored
All of the drivers in the kernel tree only call this from one of the following contexts: * drm_crtc_funcs->reset * During initial module load Since both of these contexts are guaranteed to have interrupts enabled beforehand, there's no need to use the irqsave/irqrestore variants of spin_(un)lock(). So, fix this to make the irq context of this function more obvious. Signed-off-by:
