git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing cleanup from Steven Rostedt: "Remove second argument of __assign_str() The __assign_str() macro logic of the TRACE_EVENT() macro was optimized so that it no longer needs the second argument. The __assign_str() is always matched with __string() field that takes a field name and the source for that field: __string(field, source) The TRACE_EVENT() macro logic will save off the source value and then use that value to copy into the ring buffer via the __assign_str(). Before commit c1fa617caeb0 ("tracing: Rework __assign_str() and __string() to not duplicate getting the string"), the __assign_str() needed the second argument which would perform the same logic as the __string() source parameter did. Not only would this add overhead, but it was error prone as if the __assign_str() source produced something different, it may not have allocated enough for the string in the ring buffer (as the __string() source was used to determine how much to allocate) Now that the __assign_str() just uses the same string that was used in __string() it no longer needs the source parameter. It can now be removed" * tag 'trace-assign-str-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing/treewide: Remove second parameter of __assign_str()
2024-05-22tracing/treewide: Remove second parameter of __assign_str()Steven Rostedt (Google)
With the rework of how the __string() handles dynamic strings where it saves off the source string in field in the helper structure[1], the assignment of that value to the trace event field is stored in the helper value and does not need to be passed in again. This means that with: __string(field, mystring) Which use to be assigned with __assign_str(field, mystring), no longer needs the second parameter and it is unused. With this, __assign_str() will now only get a single parameter. There's over 700 users of __assign_str() and because coccinelle does not handle the TRACE_EVENT() macro I ended up using the following sed script: git grep -l __assign_str | while read a ; do sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file; mv /tmp/test-file $a; done I then searched for __assign_str() that did not end with ';' as those were multi line assignments that the sed script above would fail to catch. Note, the same updates will need to be done for: __assign_str_len() __assign_rel_str() __assign_rel_str_len() I tested this with both an allmodconfig and an allyesconfig (build only for both).

2023-11-24drm: Disable the cursor plane on atomic contexts with virtualized driversZack Rusin
Cursor planes on virtualized drivers have special meaning and require that the clients handle them in specific ways, e.g. the cursor plane should react to the mouse movement the way a mouse cursor would be expected to and the client is required to set hotspot properties on it in order for the mouse events to be routed correctly. This breaks the contract as specified by the "universal planes". Fix it by disabling the cursor planes on virtualized drivers while adding a foundation on top of which it's possible to special case mouse cursor planes for clients that want it. Disabling the cursor planes makes some kms compositors which were broken, e.g. Weston, fallback to software cursor which works fine or at least better than currently while having no effect on others, e.g. gnome-shell or kwin, which put virtualized drivers on a deny-list when running in atomic context to make them fallback to legacy kms and avoid this issue.

2023-11-11drm/uapi: add explicit virtgpu context debug nameGurchetan Singh
There are two problems with the current method of determining the virtio-gpu debug name. 1) TASK_COMM_LEN is defined to be 16 bytes only, and this is a Linux kernel idiom (see PR_SET_NAME + PR_GET_NAME). Though, Android/FreeBSD get around this via setprogname(..)/getprogname(..) in libc. On Android, names longer than 16 bytes are common. For example, one often encounters a program like "com.android.systemui". The virtio-gpu spec allows the debug name to be up to 64 bytes, so ideally userspace should be able to set debug names up to 64 bytes. 2) The current implementation determines the debug name using whatever task initiated virtgpu. This is could be a "RenderThread" of a larger program, when we actually want to propagate the debug name of the program. To fix these issues, add a new CONTEXT_INIT param that allows userspace to set the debug name when creating a context. It takes a null-terminated C-string as the param value. The length of the string (excluding the terminator) **should** be <= 64 bytes. Otherwise, the debug_name will be truncated to 64 bytes.

2023-10-06drm/virtio: Use pci_is_vga() to identify VGA devicesSui Jingfeng
Use pci_is_vga() to identify VGA devices instead of open-coding the class test. This means virtio_gpu_pci_quirk() will apply to old PCI_CLASS_NOT_DEFINED_VGA (0x0001) devices as well as the PCI_CLASS_DISPLAY_VGA (0x0300) devices it did previously.

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct virtio_gpu_object_array.

2023-07-09drm/virtio: Conditionally allocate virtio_gpu_fenceGurchetan Singh
We don't want to create a fence for every command submission. It's only necessary when userspace provides a waitable token for submission. This could be: 1) bo_handles, to be used with VIRTGPU_WAIT 2) out_fence_fd, to be used with dma_fence apis 3) a ring_idx provided with VIRTGPU_CONTEXT_PARAM_POLL_RINGS_MASK + DRM event API 4) syncobjs in the future The use case for just submitting a command to the host, and expecting no response. For example, gfxstream has GFXSTREAM_CONTEXT_PING that just wakes up the host side worker threads. There's also CROSS_DOMAIN_CMD_SEND which just sends data to the Wayland server. This prevents the need to signal the automatically created virtio_gpu_fence. In addition, VIRTGPU_EXECBUF_RING_IDX is checked when creating a DRM event object. VIRTGPU_CONTEXT_PARAM_POLL_RINGS_MASK is already defined in terms of per-context rings. It was theoretically possible to create a DRM event on the global timeline (ring_idx == 0), if the context enabled DRM event polling. However, that wouldn't work and userspace (Sommelier). Explicitly disallow it for clarity.

The optimization is done by using optimal ordering of the job's submission steps, reducing code path from the start of the ioctl to the point of pushing job to virtio queue.

VirtIO-GPU got a new config option for disabling KMS. There were two problems left unnoticed during review when the new option was added: 1. The IS_ENABLED(CONFIG_DRM_VIRTIO_GPU_KMS) check in the code was inverted, hence KMS was disabled when it should be enabled and vice versa. 2. The disabled KMS crashed kernel with a NULL dereference in drm_kms_helper_hotplug_event(), which shall not be invoked with a disabled KMS. Fix the inverted config option check in the code and skip handling the VIRTIO_GPU_EVENT_DISPLAY sent by host when KMS is disabled in guest to fix the crash.

Add a build option to disable modesetting support. This is useful in cases where the guest only needs to use the GPU in a headless mode, or (such as in the CrOS usage) window surfaces are proxied to a host compositor. As the modesetting ioctls are a big surface area for potential security bugs to be found (it's happened in the past, we should assume it will again in the future), it makes sense to have a build option to disable those ioctls in cases where they serve no legitimate purpose. v2: Use more if (IS_ENABLED(...)) v3: Also permit the host to advertise no scanouts v4: Spiff out commit msg v5: Make num_scanouts==0 and DRM_VIRTIO_GPU_KMS=n behave the same v6: Drop conditionally building virtgpu_display.c and early-out of it's init/fini fxns instead Signed-off-by: Rob Clark <robdclark@chromium.org> Reviewed-by: Dmitry Osipenko <dmitry.osipenko@collabora.com> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Dmitry Osipenko <dmitry.osipenko@collabora.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230302233506.3146290-1-robdclark@gmail.com

2023-02-06drm/virtio: exbuf->fence_fd unmodified on interrupted waitRyan Neph
An interrupted dma_fence_wait() becomes an -ERESTARTSYS returned to userspace ioctl(DRM_IOCTL_VIRTGPU_EXECBUFFER) calls, prompting to retry the ioctl(), but the passed exbuf->fence_fd has been reset to -1, making the retry attempt fail at sync_file_get_fence(). The uapi for DRM_IOCTL_VIRTGPU_EXECBUFFER is changed to retain the passed value for exbuf->fence_fd when returning anything besides a successful result from the ioctl.

2023-01-31Merge v6.2-rc6 into drm-nextDaniel Vetter
Due to holidays we started -next with more -fixes in-flight than usual, and people have been asking where they are. Backmerge to get things better in sync. Conflicts: - Tiny conflict in drm_fbdev_generic.c between variable rename and missing error handling that got added. - Conflict in drm_fb_helper.c between the added call to vgaswitcheroo in drm_fb_helper_single_fb_probe and a refactor patch that extracted lots of helpers and incidentally removed the dev local variable. Readd it to make things compile. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2023-01-10drm/virtio: Fix GEM handle creation UAFRob Clark
Userspace can guess the handle value and try to race GEM object creation with handle close, resulting in a use-after-free if we dereference the object after dropping the handle's reference. For that reason, dropping the handle's reference must be done *after* we are done dereferencing the object.
