drm/panthor: Add missing explicit padding in drm_panthor_gpu_info

2025-08-15T14:38:37Z

[ Upstream commit 95cbab48782bf62e4093837dc15ac6133902c12f ] drm_panthor_gpu_info::shader_present is currently automatically offset by 4 byte to meet Arm's 32-bit/64-bit field alignment rules, but those constraints don't stand on 32-bit x86 and cause a mismatch when running an x86 binary in a user emulated environment like FEX. It's also generally agreed that uAPIs should explicitly pad their struct fields, which we originally intended to do, but a mistake slipped through during the submission process, leading drm_panthor_gpu_info::shader_present to be misaligned. This uAPI change doesn't break any of the existing users of panthor which are either arm32 or arm64 where the 64-bit alignment of u64 fields is already enforced a the compiler level. Changes in v2: - Rename the garbage field into pad0 and adjust the comment accordingly - Add Liviu's A-b Changes in v3: - Add R-bs Fixes: 0f25e493a246 ("drm/panthor: Add uAPI") Acked-by: Liviu Dudau Reviewed-by: Adrián Larumbe Reviewed-by: Steven Price Link: https://lore.kernel.org/r/20250606080932.4140010-2-boris.brezillon@collabora.com Signed-off-by: Boris Brezillon Signed-off-by: Sasha Levin

drm/xe/pxp: Clarify PXP queue creation behavior if PXP is not ready

2025-06-05T16:07:33Z

The expected flow of operations when using PXP is to query the PXP status and wait for it to transition to "ready" before attempting to create an exec_queue. This flow is followed by the Mesa driver, but there is no guarantee that an incorrectly coded (or malicious) app will not attempt to create the queue first without querying the status. Therefore, we need to clarify what the expected behavior of the queue creation ioctl is in this scenario. Currently, the ioctl always fails with an -EBUSY code no matter the error, but for consistency it is better to distinguish between "failed to init" (-EIO) and "not ready" (-EBUSY), the same way the query ioctl does. Note that, while this is a change in the return code of an ioctl, the behavior of the ioctl in this particular corner case was not clearly spec'd, so no one should have been relying on it (and we know that Mesa, which is the only known userspace for this, didn't). v2: Minor rework of the doc (Rodrigo) Fixes: 72d479601d67 ("drm/xe/pxp/uapi: Add userspace and LRC support for PXP-using queues") Signed-off-by: Daniele Ceraolo Spurio Cc: John Harrison Cc: José Roberto de Souza Reviewed-by: José Roberto de Souza Reviewed-by: John Harrison Acked-by: Rodrigo Vivi Link: https://lore.kernel.org/r/20250522225401.3953243-7-daniele.ceraolospurio@intel.com (cherry picked from commit 21784ca96025b62d95b670b7639ad70ddafa69b8) Signed-off-by: Thomas Hellström

drm: nova-drm: add initial driver skeleton

2025-05-12T18:48:15Z

Add the initial nova-drm driver skeleton. nova-drm is connected to nova-core through the auxiliary bus and implements the DRM parts of the nova driver stack. For now, it implements the fundamental DRM abstractions, i.e. creates a DRM device and registers it, exposing a three sample IOCTLs. DRM_IOCTL_NOVA_GETPARAM - provides the PCI bar size from the bar that maps the GPUs VRAM from nova-core DRM_IOCTL_NOVA_GEM_CREATE - creates a new dummy DRM GEM object and returns a handle DRM_IOCTL_NOVA_GEM_INFO - provides metadata for the DRM GEM object behind a given handle I implemented a small userspace test suite [1] that utilizes this interface.
