[PATCH] gpu: ipu-v3: Allow channel burst locking on i.MX6 only
by Philipp Zabel 11 Oct '17

11 Oct '17

The IDMAC_LOCK_EN registers on i.MX51 have a different layout, and on i.MX53 enabling the lock feature causes bursts to get lost. Restrict enabling the burst lock feature to i.MX6.

[PATCH] drm/i915: remove redundant check on has_aliasing_ppgtt
by Colin King 10 Oct '17

10 Oct '17

From: Colin Ian King <colin.king(a)canonical.com> There is a previous check to on has_aliasing_ppgtt that returns 0 if it is false, so it is impossible for has_aliasing_ppgtt to be false on the final return of function intel_sanitize_enable_ppgtt, so final return in the function always will return 1. Hence the redundant ternary operator can be replaced with a return 1. Detected by CoverityScan, CID#1357136 ("Logically dead code") Signed-off-by: Colin Ian King <colin.king(a)… [View More]

[PATCH 00/12] radix-tree: split out struct radix_tree_root out to <linux/radix-tree-root.h>
by Masahiro Yamada 10 Oct '17

10 Oct '17

The motivation of this series is to cut down unnecessary header dependency in terms of radix tree. Sub-systems or drivers that use radix-tree for data management typically embed struct radix_tree_root in their data structures, like this: struct foo { ... struct radix_tree_root foo_tree; ... }; So, <linux/foo.h> needs to include <linux/radix-tree.h>, therefore, users of <linux/foo.h> include a lot of bloat from <linux/radix-tree.h>. If you see … [View More]the definition of radix_tree_root, struct radix_tree_root { gfp_t gfp_mask; struct radix_tree_node __rcu *rnode; }; it is a very simple structure. It only depends on <linux/types.h> for gfp_t and <linux/compiler.h> for __rcu. By splitting out the radix_tree_root definition, we can reduce the header file dependency. Reducing the header dependency will help for speeding the kernel build, suppressing unnecessary recompile of objects during git-bisect'ing, etc. The patch 1 is a trivial clean-up; it is just here to avoid conflict. The patch 2 is the main part of this series; split out struct radix_tree_root. The rest of the series replace <linux/radix-tree.h> with <linux/radix-tree-root.h> where appropriate. Please review if the idea is OK. If it is OK, I'd like to know how to apply the series. Perhaps, the first two for v4.15. Then, rest of series will be sent per-subsystem for v4.16? Or, can somebody take care of the whole series? I checked allmodconfig for x86 and arm64. I am expecting 0 day testing will check it too.
