[PATCH 05/40] drm/i915: Handle incomplete Z_FINISH for compressed error states

by Chris Wilson

The final call to zlib_deflate(Z_FINISH) may require more output space to be allocated and so needs to re-invoked. Failure to do so in the current code leads to incomplete zlib streams (albeit intact due to the use of Z_SYNC_FLUSH) resulting in the occasional short object capture.

[GIT PULL] ring-buffer: Allow for rescheduling when removing pages

by Steven Rostedt

Linus (aka Greg), Vaibhav Nagarnaik found that modifying the ring buffer size could cause a huge latency in the system because it does a while loop to free pages without releasing the CPU (on non preempt kernels). In a case where there are hundreds of thousands of pages to free it could actually cause a system stall. A properly place cond_resched() solves this issue. Please pull the latest trace-v4.19-rc4 tree, which can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git trace-v4.19-rc4 Tag SHA1: 977e4fb3741e24151a255ee13bd4a1224545ae4e Head SHA1: 83f365554e47997ec68dc4eca3f5dce525cd15c3 Vaibhav Nagarnaik (1): ring-buffer: Allow for rescheduling when removing pages ---- kernel/trace/ring_buffer.c | 2 ++ 1 file changed, 2 insertions(+) --------------------------- commit 83f365554e47997ec68dc4eca3f5dce525cd15c3 Author: Vaibhav Nagarnaik <vnagarnaik(a)google.com> Date: Fri Sep 7 15:31:29 2018 -0700 ring-buffer: Allow for rescheduling when removing pages When reducing ring buffer size, pages are removed by scheduling a work item on each CPU for the corresponding CPU ring buffer. After the pages are removed from ring buffer linked list, the pages are free()d in a tight loop. The loop does not give up CPU until all pages are removed. In a worst case behavior, when lot of pages are to be freed, it can cause system stall. After the pages are removed from the list, the free() can happen while the work is rescheduled. Call cond_resched() in the loop to prevent the system hangup.

[PATCH 13/19] mtd: nand: pxa3xx: Fix READOOB implementation

by kostap＠marvell.com

From: Boris Brezillon <boris.brezillon(a)free-electrons.com> In the current driver, OOB bytes are accessed in raw mode, and when a page access is done with NDCR_SPARE_EN set and NDCR_ECC_EN cleared, the driver must read the whole spare area (64 bytes in case of a 2k page, 16 bytes for a 512 page). The driver was only reading the free OOB bytes, which was leaving some unread data in the FIFO and was somehow leading to a timeout. We could patch the driver to read ->spare_size + ->ecc_size instead of just ->spare_size when READOOB is requested, but we'd better make in-band and OOB accesses consistent. Since the driver is always accessing in-band data in non-raw mode (with the ECC engine enabled), we should also access OOB data in this mode. That's particularly useful when using the BCH engine because in this mode the free OOB bytes are also ECC protected.

[PATCH 5/6] drm/i915: Fix intel_dp_mst_best_encoder()

by Lyude Paul

Currently, i915 appears to rely on blocking modesets on no-longer-present MSTB ports by simply returning NULL for ->best_encoder(), which in turn causes any new atomic commits that don't disable the CRTC to fail. This is wrong however, since we still want to allow userspace to disable CRTCs on no-longer-present MSTB ports by changing the DPMS state to off and this still requires that we retrieve an encoder. So, fix this by always returning a valid encoder regardless of the state of the MST port. Additionally, make intel_dp_mst_atomic_check() simply rely on drm_dp_mst_connector_atomic_check() to prevent new modesets on no-longer-present MSTB ports.

[PATCH 4/6] drm/i915: Skip vcpi allocation for MSTB ports that are gone

by Lyude Paul

Since we need to be able to allow DPMS on->off prop changes after an MST port has disappeared from the system, we need to be able to make sure we can compute a config for the resulting atomic commit. Currently this is impossible when the port has disappeared, since the VCPI slot searching we try to do in intel_dp_mst_compute_config() will fail with -EINVAL. Since the only commits we want to allow on no-longer-present MST ports are ones that shut off display hardware, we already know that no VCPI allocations are needed. So, hardcode the VCPI slot count to 0 when intel_dp_mst_compute_config() is called on an MST port that's gone.
