VPU on MTL has hardware optimizations and does not require 10ms D0 - D3hot transition delay imposed by PCI specification (PCIe r6.0, sec 5.9.) . The delay removal is traditionally done by adding PCI ID to quirk_remove_d3hot_delay() in drivers/pci/quirks.c . But since we do not need that optimization before driver probe and we can better specify in the ivpu driver on what (future) hardware use the optimization, we do not use quirk_remove_d3hot_delay() for that.

The TC358767/TC358867/TC9595 are capable of DSI burst mode, which is more energy efficient than the non-burst modes. Make use of it. The TC358767/TC358867/TC9595 are capable of DSI non-continuous clock, since it sources the internal PLL clock from external clock source. The DSI non-continuous clock further reduces power utilization. The TC358767/TC358867/TC9595 may use DSI LPM for command transmissions, make sure this is configured correctly in the DSI mode flags.

We don't populate drm_driver.gem_prime_import_sg_table so only DMA-BUFs exported from our own device can be imported. We don't populate drm_gem_object_funcs.get_sg_table so DMA-BUFs cannot be imported into another device. Still, this is useful to user-space to share buffers between processes and between API boundaries (e.g. wlroots hard-requires PRIME import/export support). v2: expand commit message Signed-off-by:

drm_gem_map_dma_buf() requires drm_gem_object_funcs.get_sg_table to be implemented, or else WARNs. Allow drivers to leave this hook unimplemented to implement purely local DMA-BUFs (ie, DMA-BUFs which cannot be imported anywhere else but the device which allocated them). In that case, reject imports to other devices in drm_gem_map_attach(). v2: new patch v3: use ENOSYS Signed-off-by:

lima maintains a context manager per drm_file, similar to amdgpu. In order to account for the complete usage per drm_file, all of the associated contexts need to be considered.

Some SoCs implementing ARM Mali GPUs are subject to speed binning: this means that some versions of the same SoC model may need to be limited to a slower frequency compared to the other: this is being addressed by reading nvmem (usually, an eFuse array) containing a number that identifies the speed binning of the chip, which is usually related to silicon quality. To address such situation, add basic support for reading the speed-bin through nvmem, as to make it possible to specify the supported hardware in the OPP table for GPUs. This commit also keeps compatibility with any platform that does not specify (and does not even support) speed-binning. Signed-off-by:

https://gitlab.freedesktop.org/drm/msmDaniel Vetter authored
This series adds a deadline hint to fences, so realtime deadlines such as vblank can be communicated to the fence signaller for power/ frequency management decisions. This is partially inspired by a trick i915 does, but implemented via dma-fence for a couple of reasons: 1) To continue to be able to use the atomic helpers 2) To support cases where display and gpu are different drivers See https://patchwork.freedesktop.org/series/93035/ This does not yet add any UAPI, although this will be needed in a number of cases: 1) Workloads "ping-ponging" between CPU and GPU, where we don't want the GPU freq governor to interpret time stalled waiting for GPU as "idle" time 2) Cases where the compositor is waiting for fences to be signaled before issuing the atomic ioctl, for example to maintain 60fps cursor updates even when the GPU is not able to maintain that framerate.
