This series adds new BO allocation flags PANFROST_BO_HEAP and PANFROST_BO_NOEXEC. The heap allocations are paged in on GPU page faults. Tomeu reports he has tested this in the panfrost CI. This is based on drm-misc-next. An updated branch is here[1]. v3: - Retain shared irq support, splitting IRQ changes to separate patch (6/8) - Stop leaking SG tables - Prevent mmap and pinning pages for heap BOs Rob [1] git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux.git panfrost/heap-noexec Rob Herring (8): drm/gem: Allow sparsely populated page arrays in drm_gem_put_pages drm/shmem: Put pages independent of a SG table being set drm/panfrost: Restructure the GEM object creation drm/panfrost: Split panfrost_mmu_map SG list mapping to its own function drm/panfrost: Add a no execute flag for BO allocations drm/panfrost: Convert MMU IRQ handler to threaded handler drm/panfrost: Add support for GPU heap allocations drm/panfrost: Bump driver version to 1.1 drivers/gpu/drm/drm_gem.c | 3 + drivers/gpu/drm/drm_gem_shmem_helper.c | 4 +- drivers/gpu/drm/panfrost/TODO | 2 - drivers/gpu/drm/panfrost/panfrost_drv.c | 65 ++++++-- drivers/gpu/drm/panfrost/panfrost_gem.c | 106 +++++++++++-- drivers/gpu/drm/panfrost/panfrost_gem.h | 16 +- drivers/gpu/drm/panfrost/panfrost_mmu.c | 200 ++++++++++++++++++++---- include/uapi/drm/panfrost_drm.h | 3 + 8 files changed, 333 insertions(+), 66 deletions(-) -- 2.20.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
