This series fixes a number of use-after-frees in nouveau's postclose() handler. It was discovered by pointing IGT's core_hotunplug tests at a nouveau device, but the steps to reproduce it are simple: 1. Open the device file 2. Unbind the driver or remove the device 3. Close the file opened in step 1. During the device removal, the nouveau_drm structure is de-allocated, but is

Hi folks, Currently, when the device is removed (or the driver is unbound) the nouveau_drm structure de-allocated. However, it's still accessible from and used by some DRM layer callbacks. For example, file handles can be closed after the device has been removed (physically or otherwise). This series converts the Nouveau device structure to be allocated and de-allocated with the

This series is intended to add support for shutting down the GPU on kernel shutdown/reboot using the ->shutdown() hook, similar to what amdgpu does. This is mainly intended to workaround a bios issue on the P50 that was preventing nouveau from initializing the dedicated GM107 GPU on that system properly. You can find more details on this issue in the patch labeled "Shut down GPU on kernel

Modernize vga_switcheroo by using a device link to enforce a runtime PM dependency from an HDA controller to the GPU it's integrated into, v2. Changes since v1: - Replace patch [1/7] to use pci_save_state() / pci_restore_state() for consistency between runtime PM code path of bound and unbound devices. (Rafael, Bjorn) - Patch [5/7]: Drop an unnecessary initialization. (Bjorn) Rephrase

Modernize vga_switcheroo by using a "device link" to enforce a runtime PM dependency from an HDA controller to the GPU it's integrated into. Remove thereby obsoleted code and fix a bunch of bugs. Device links were introduced in v4.10. Users might see a small power saving if the discrete GPU is in use and its HDA controller is not, because the HDA controller is now allowed to runtime
