Subject: [PATCH v3 0/8] drm/panfrost: Add heap and no execute buffer allocation
Date: Fri, 2 Aug 2019 13:51:42 -0600 [thread overview]
Message-ID: <20190802195150.23207-1-robh@kernel.org> (raw)
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 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
