Prevent userspace accesses to the DRM device from causing use-after-frees by unplugging the device before we remove it. This causes any further userspace accesses to result in an error without further calls into this driver's internals. Fixes: d76271d2 ("drm: xlnx: DRM/KMS driver for Xilinx ZynqMP DisplayPort Subsystem") Closes: https://lore.kernel.org/dri-devel/4d8f4c9b-2efb-4774-9a37-2f257f79b2c9@linux.dev/ Signed-off-by:

Secondary preemption buffer is accessible by NPU's DMA and can be allocated with addresses above 4 GB. Move secondary preemption buffer allocation from SHAVE range which is much smaller (2GB) to DMA range. This allows to allocate more command queues with corresponding preemption buffers without running out of address range. Signed-off-by:

Increase DMA address range to: * 128 GB on 37xx (due to MMU limitations) * 256 GB on other generations Merge User and DMA ranges on 40xx and above as it is possible to access whole 256 GBs from both FW and DMA. Increase User range on 37xx from 255MB to 511MB to allow loading very large models. Do not set global_alias_pio_base/size on other generations than 37xx as it's only used on 37xx anyway.

Do not allocate preemption buffers when Mid Inference Preemption (MIP) is disabled through test mode. Rename IVPU_TEST_MODE_PREEMPTION_DISABLE to IVPU_TEST_MODE_MIP_DISABLE to better describe that this test mode only disables MIP - job level preemption will still occur. Signed-off-by:

Remove custom ivpu_id_alloc() wrapper used for ID allocations and replace it with standard xa_alloc_cyclic() API. The idea behind ivpu_id_alloc() was to have monotonic IDs, so the driver is easier to debug because same IDs are not reused all over. The same can be achieved just by using appropriate Linux API.

Defer root page table allocation and unify context init/fini functions. Move allocation of the root page table from the file_priv_open function to perform a lazy allocation approach during ivpu_bo_pin(). By doing so, we avoid the overhead of allocating page tables for simple operations like GET_PARAM that do not require them. Additionally, the MMU context descriptor table initialization has been moved to the ivpu_mmu_context_map_page function. This change streamlines the process and ensures that the descriptor table is only initialized when it is actually needed. Refactor init/fini functions to remove redundant code and make the context management more straightforward. Overall, these changes lead to a reduction in the time taken by the file descriptor open operation, as the costly root page table allocation is now avoided for operations that do not require it.

The Sahara protocol has a crashdump functionality. In the hello exchange, the device can advertise it has a memory dump available for the host to collect. Instead of the device making requests of the host, the host requests data from the device which can be later analyzed. Implement this functionality and utilize the devcoredump framework for handing the dump over to userspace. Similar to how firmware loading in Sahara involves multiple files, crashdump can consist of multiple files for different parts of the dump. Structure these into a single buffer that userspace can parse and extract the original files from. Reviewed-by:

drm_sched_job_init() has no control over how users allocate struct drm_sched_job. Unfortunately, the function can also not set some struct members such as job->sched. This could theoretically lead to UB by users dereferencing the struct's pointer members too early. It is easier to debug such issues if these pointers are initialized to NULL, so dereferencing them causes a NULL pointer exception. Accordingly, drm_sched_entity_init() does precisely that and initializes its struct with memset(). Initialize parameter "job" to 0 in drm_sched_job_init(). Signed-off-by:
