This patch series is the leftovers of a patch series sent in September 2023 [1] in an attempt to get some of the patches landed finally.

This patch series came about after a _long_ discussion between me and Maxime Ripard in response to a different patch I sent out [1]. As part of that discussion, we realized that it would be good if DRM drivers consistently called drm_atomic_helper_shutdown() properly at shutdown and driver remove time as it's documented that they should do. The eventual goal of this would be to enable removing

GP10B is the chip used in Tegra X2 SoCs. This patchset adds support for its base engines after reworking secboot a bit to accomodate its calling convention better. This patchset has been tested rendering simple off-screen buffers using Mesa and yielded the expected result. Alexandre Courbot (15): secboot: allow to boot multiple falcons secboot: pass instance to LS firmware loaders secboot:

TTM-allocated coherent objects were populated using the DMA API and accessed using the mapping it returned to workaround coherency issues. These issues seem to have been solved, thus remove this extra case to handle and use the regular kernel mapping functions.

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

From: Thierry Reding <treding at nvidia.com> Hi Ben, here's a revised subset of the patches I had sent out a couple of weeks ago. I've reworked the BAR2 accesses in the way that you had suggested, which at least for GP10B turned out to be fairly trivial to do. I have not looked in detail at this for GV11B yet, but a cursory look showed that BAR2 is accessed in more places, so the
