Stop calling drm_bridge_remove() for bridges allocated/managed by other drivers in the remove paths of meson_encoder_{cvbs,dsi,hdmi}. drm_bridge_remove() unregisters the bridge so it cannot be used anymore. Doing so for bridges we don't own can lead to the video pipeline not being able to come up after -EPROBE_DEFER of the VPU because we're unregistering a bridge that's managed by another driver. The other driver doesn't know that we have unregistered it's bridge and on subsequent .probe() we're not able to find those bridges anymore (since nobody re-creates them). This fixes probe errors on Meson8b boards with the CVBS outputs enabled.

Few users have observed display corruption when they boot the machine to KDE Plasma or playing games. We have root caused the problem that whenever alloc_range() couldn't find the required memory blocks the function was returning SUCCESS in some of the corner cases. The right approach would be if the total allocated size is less than the required size, the function should return -ENOSPC.

nouveau_abi16_ioctl_channel_alloc() and nouveau_cli_init() simply call their corresponding *_fini() counterpart. This can lead to nouveau_sched_fini() being called without struct nouveau_sched ever being initialized in the first place. Instead of embedding struct nouveau_sched into struct nouveau_cli and struct nouveau_chan_abi16, allocate struct nouveau_sched separately, such that we can check for the corresponding pointer to be NULL in the particular *_fini() functions. It makes sense to allocate struct nouveau_sched separately anyway, since in a subsequent commit we can also avoid to allocate a struct nouveau_sched in nouveau_abi16_ioctl_channel_alloc() at all, if the VM_BIND uAPI has been disabled due to the legacy uAPI being used.

Issue IP reset before shutdown in order to complete all upstream requests to the SOC. Without this DevTLB is complaining about incomplete transactions and NPU cannot resume from suspend. This problem is only happening on recent IFWI releases. IP reset in rare corner cases can mess up PCI configuration, so save it before the reset. After this happens it is also impossible to issue PLL requests and D0->D3->D0 cycle is needed to recover the NPU. Add WP 0 request on power up, so the PUNIT is always notified about NPU reset. Use D0/D3 cycle for recovery as it can recover from failed IP reset and FLR cannot. Fixes: 3f7c0634 ("accel/ivpu/37xx: Fix hangs related to MMIO reset") Signed-off-by:

Timur Tabi authored
Nouveau manages GSP-RM DMA buffers with nvkm_gsp_mem objects. Several of these buffers are never dealloced. Some of them can be deallocated right after GSP-RM is initialized, but the rest need to stay until the driver unloads. Also futher bullet-proof these objects by poisoning the buffer and clearing the nvkm_gsp_mem object when it is deallocated. Poisoning the buffer should trigger an error (or crash) from GSP-RM if it tries to access the buffer after we've deallocated it, because we were wrong about when it is safe to deallocate. Finally, change the mem->size field to a size_t because that's the same type that dma_alloc_coherent expects.

DMA buffers allocated from the CMA dma-buf heap get counted under RssFile for processes that map them and trigger page faults. In addition to the incorrect accounting reported to userspace, reclaim behavior was influenced by the MM_FILEPAGES counter until linux 6.8, but this memory is not reclaimable. [1] Change the CMA dma-buf heap to set VM_PFNMAP on the VMA so MM does not poke at the memory managed by this dma-buf heap, and use vmf_insert_pfn to correct the RSS accounting. The system dma-buf heap does not suffer from this issue since remap_pfn_range is used during the mmap of the buffer, which also sets VM_PFNMAP on the VMA.

This reverts commit 60aebc95. Commit 60aebc95 ("drivers/firmware: Move sysfb_init() from device_initcall to subsys_initcall_sync") messes up initialization order of the graphics drivers and leads to blank displays on some systems. So revert the commit. To make the display drivers fully independent from initialization order requires to track framebuffer memory by device and independently from the loaded drivers. The kernel currently lacks the infrastructure to do so. Reported-by:

This was not supported properly. A buffer was imported to another VPU context as a separate buffer object with duplicated sgt. Both exported and imported buffers could be DMA mapped causing a double mapping on the same device. Buffers imported from another VPU context will now just increase reference count, leaving only a single sgt, fixing the problem above. Buffers still can't be shared among VPU contexts because each has its own MMU mapping and ivpu_bo only supports single MMU mappings. The solution would be to use a mapping list as in panfrost or etnaviv drivers and it will be implemented in future if required. Signed-off-by:
