From: Thierry Reding <treding at nvidia.com> Most IOMMU drivers only need to free the memory allocated for each reserved region. Instead of open-coding the loop to do this in each driver, extract the code into a common function that can be used by all these drivers. Changes in v2: - change subject prefix to "iommu: vi...

From: Thierry Reding <treding at nvidia.com> Tegra firmware doesn't actually use any version numbers and passing -1 causes the existing firmware binaries not to be found.

From: Thierry Reding <treding at nvidia.com> As part of commit cfea88a4d866 ("drm/nouveau: Start using new drm_dev initialization helpers"), the initialization of the Nouveau DRM device was reworked and along the way the platform driver initialization was left incomplete. Add a call to nouveau_drm_device_init() to...

From: Thierry Reding <treding at nvidia.com> The memory allocated for a nouveau_cli object in nouveau_cli_create() is never freed. Free the memory in nouveau_cli_destroy() to plug this leak. kmemleak recorded this after running a couple of nouveau test programs. Note that kmemleak points at drm_open_helper() because for so...

From: Thierry Reding <treding at nvidia.com> An unfortunate interaction between the 32-bit ARM DMA/IOMMU mapping code and Tegra SMMU driver changes to support IOMMU groups introduced a boot- time regression on Tegra124. This was caught very late because none of the standard configurations that are tested on Tegra enable the...

From: Thierry Reding <treding at nvidia.com> Depending on the kernel configuration, early ARM architecture setup code may have attached the GPU to a DMA/IOMMU mapping that transparently uses the IOMMU to back the DMA API. Tegra requires special handling for IOMMU backed buffers (a special bit in the GPU's MMU page table...

From: Thierry Reding <treding at nvidia.com> Hi Ben, I messed up the ordering of patches in my tree a bit, so these two fixes got separated from the others. I don't consider these particularily urgent because the crash that the first one fixes only happens on gp10b which we don't enable by default yet and the secon...

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...

From: Thierry Reding <treding at nvidia.com> Hi Ben, these are fixes for a couple of issues that I've been running into when testing on various Tegra boards. The first two patches fix up issues in the fix that I had sent out earlier to fix the regression introduced in drm-misc-next. The first one is critical because it...

From: Thierry Reding <treding at nvidia.com> Hi Ben, these are a couple of patches that are in preparation for adding GV11B support. The fundamental issue that these are trying to solve is that the GV11B is the first Tegra incarnation of the GPU where the aperture really matters. All prior generations would accept any of t...
