[PATCH] drm/i915: Enable display WA#1183 from its correct spot

by Imre Deak

The DMC FW specific part of display WA#1183 is supposed to be enabled whenever enabling DC5 or DC6, so move it to the DC6 enable function from the DC6 disable function. I noticed this after Daniel's patch to remove the unused skl_disable_dc6() function.

[PATCH 2/2] drm/i915/dsi: fix dphy param field widths and range checks for chv+

by Jani Nikula

Current CHV and BXT bspec says the dphy param register has four 8-bit fields instead of the smaller VLV field widths. CHV bspec mentions the register has changed since K0, but there's no indication of what exactly changed. Lacking further details, change the field widths for all CHV and later. Define the max values based on the platform. Also define them based on the register definitions instead of duplicating information.

[PATCH] rtlwifi: cleanup 8723be ant_sel definition

by pkshih＠realtek.com

From: Ping-Ke Shih <pkshih(a)realtek.com> The module parameter ant_sel is used to control antenna number and path. There is an existing enum ANT_{X2,X1} defined the antenna number, so add a new enum ANT_{MAIN,AUX} to make it readable. After this work, incorrect given values depend on ant_sel were exposed, so refill values according following definition: ant_sel ant_num ant_path print_label 1 ANT_X1 ANT_AUX #2 2 ANT_X2 ANT_MAIN #1 Then, the workaround in halbtcoutsrc.c was removed. The experimental results with single antenna connected to specific path are in following: ant_sel ANT_MAIN(#1) ANT_AUX(#2) 0 -8 -62 1 -62 -10 2 -6 -60 Signed-off-by: Ping-Ke Shih <pkshih(a)realtek.com> Cc: Stable <stable(a)vger.kernel.org> # 4.7+ Reviewed-by: Larry Finger <Larry.Finger(a)lwfinger.net> --- Hi Kalle, This patch would send to 4.17.

[PATCH] kprobes: Fix random address output of blacklist file

by Thomas Richter

File /sys/kernel/debug/kprobes/blacklist displays random addresses: [root@s8360046 linux]# cat /sys/kernel/debug/kprobes/blacklist 0x0000000047149a90-0x00000000bfcb099a print_type_x8 .... This breaks 'perf probe' which uses the blacklist file to prohibit probes on certain functions by checking the address range. Fix this by printing the correct (unhashed) address. The file mode is read all but this is not an issue as the file hierarchy points out: # ls -ld /sys/ /sys/kernel/ /sys/kernel/debug/ /sys/kernel/debug/kprobes/ /sys/kernel/debug/kprobes/blacklist dr-xr-xr-x 12 root root 0 Apr 19 07:56 /sys/ drwxr-xr-x 8 root root 0 Apr 19 07:56 /sys/kernel/ drwx------ 16 root root 0 Apr 19 06:56 /sys/kernel/debug/ drwxr-xr-x 2 root root 0 Apr 19 06:56 /sys/kernel/debug/kprobes/ -r--r--r-- 1 root root 0 Apr 19 06:56 /sys/kernel/debug/kprobes/blacklist Everything in and below /sys/kernel/debug is rwx to root only, no group or others have access.

[PATCH 1/2] ALSA: hda/realtek - set PINCFG_HEADSET_MIC to parse_flags

by Hui Wang

Otherwise, the pin will be regarded as microphone, and the jack name is "Mic Phantom", it is always on in the pulseaudio even nothing is plugged into the jack. So the UI is confusing to users since the microphone always shows up in the UI even there is no microphone plugged. After adding this flag, the jack name is "Headset Mic Phantom", then the pulseaudio can handle its detection correctly.

[PATCH] drm/i915/audio: set minimum CD clock to twice the BCLK

by Jani Nikula

From: Abhay Kumar <abhay.kumar(a)intel.com> In GLK when the device boots with only 1366x768 panel without audio, HDA codec doesn't come up. In this case, the CDCLK is less than twice the BCLK. Even though audio isn't being enabled, having a too low CDCLK leads to audio probe failing altogether. Require CDCLK to be at least twice the BLCK regardless of audio. This is a minimal fix to improve things. Unfortunately, this a) leads to too high CDCLK being used when audio is not used, and b) is still not enough to fix audio probe when no outputs are connected at probe time. The proper fix would be to increase CDCLK dynamically from the audio component hooks. v2: - Address comment (Jani) - New design approach v3: - Typo fix on top of v1 v4 by Jani: rewrite commit message, add comment in code Cc: stable(a)vger.kernel.org Cc: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan(a)gmail.com> Cc: Wenkai Du <wenkai.du(a)intel.com> Reviewed-by: Wenkai Du <wenkai.du(a)intel.com> Tested-by: Wenkai Du <wenkai.du(a)intel.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=102937 Signed-off-by: Abhay Kumar <abhay.kumar(a)intel.com> Signed-off-by: Jani Nikula <jani.nikula(a)intel.com> --- drivers/gpu/drm/i915/intel_cdclk.c | 16 ++++++++++++++-- 1 file changed, 14 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_cdclk.c b/drivers/gpu/drm/i915/intel_cdclk.c index fc8b2c6e3508..32d24c69da3c 100644 --- a/drivers/gpu/drm/i915/intel_cdclk.c +++ b/drivers/gpu/drm/i915/intel_cdclk.c @@ -2140,10 +2140,22 @@ int intel_crtc_compute_min_cdclk(const struct intel_crtc_state *crtc_state) } } - /* According to BSpec, "The CD clock frequency must be at least twice + /* + * According to BSpec, "The CD clock frequency must be at least twice * the frequency of the Azalia BCLK." and BCLK is 96 MHz by default. + * + * FIXME: Check the actual, not default, BCLK being used. + * + * FIXME: This does not depend on ->has_audio because the higher CDCLK + * is required for audio probe, also when there are no audio capable + * displays connected at probe time.

[PATCH] block: Avoid executing a report or reset zones while a queue is frozen

by Bart Van Assche

This patch on itself does not change the behavior of either ioctl. However, this patch is necessary to avoid that these ioctls fail with -EIO if sd_revalidate_disk() is called while these ioctls are in progress because the current zoned block command code temporarily clears data that is needed by these ioctls.

[PATCH v4.9.y 00/42] arm64 spectre patches

by Mark Rutland

Hi Greg, These patches backport arm64 spectre mitigations to v4.9.y (based on 4.9.93). I've done this backport from scratch, following the patches in the arm64 kpti branch [1] (which contrary to its name, also has spectre patches intended for backporting). To the best of my understanding the code is correct, in the context of the v4.9.y kernel, and I've tested the series on arm64 hardware available to me, using firmware with SMCCC 1.1 and branch predictor mitigations. I've Cc'd the usual suspects for testing. For anyone willing to test this, I've pushed this out to the stable/4.9.y/spectre branch of my kernel.org repo [2]. Note that I've left off the Qualcomm Falkor patches, as it was pointed out that necessary errata workarounds for Falkor were never backported, and thus I assume that no-one is using v4.9.y on Falkor parts. Shanker, do you have any idea whether people are using v4.9.y on Falkor? Thanks, Mark.

[PATCH] drm/i915/gvt: init mmio by lri command in vgpu inhibit context

by Weinan Li

commit cd7e61b93d068a80bfe6cb55bf00f17332d831a1 upstream. There is one issue relates to Coarse Power Gating(CPG) on KBL NUC in GVT-g, vgpu can't get the correct default context by updating the registers before inhibit context submission. It always get back the hardware default value unless the inhibit context submission happened before the 1st time forcewake put. With this wrong default context, vgpu will run with incorrect state and meet unknown issues. The solution is initialize these mmios by adding lri command in ring buffer of the inhibit context, then gpu hardware has no chance to go down RC6 when lri commands are right being executed, and then vgpu can get correct default context for further use. v3: - fix code fault, use 'for' to loop through mmio render list(Zhenyu) v4: - save the count of engine mmio need to be restored for inhibit context and refine some comments.

[PATCH v2 1/4] MIPS: memset.S: Fix clobber of v1 in last_fixup

by Matt Redfearn

The label .Llast_fixup\@ is jumped to on page fault within the final byte set loop of memset (on < MIPSR6 architectures). For some reason, in this fault handler, the v1 register is randomly set to a2 & STORMASK. This clobbers v1 for the calling function. This can be observed with the following test code: static int __init __attribute__((optimize("O0"))) test_clear_user(void) { register int t asm("v1"); char *test; int j, k; pr_info("\n\n\nTesting clear_user\n"); test = vmalloc(PAGE_SIZE); for (j = 256; j < 512; j++) { t = 0xa5a5a5a5; if ((k = clear_user(test + PAGE_SIZE - 256, j)) != j - 256) { pr_err("clear_user (%px %d) returned %d\n", test + PAGE_SIZE - 256, j, k); } if (t != 0xa5a5a5a5) { pr_err("v1 was clobbered to 0x%x!\n", t); } } return 0; } late_initcall(test_clear_user); Which demonstrates that v1 is indeed clobbered (MIPS64): Testing clear_user v1 was clobbered to 0x1! v1 was clobbered to 0x2! v1 was clobbered to 0x3! v1 was clobbered to 0x4! v1 was clobbered to 0x5! v1 was clobbered to 0x6! v1 was clobbered to 0x7! Since the number of bytes that could not be set is already contained in a2, the andi placing a value in v1 is not necessary and actively harmful in clobbering v1.

Unfortunately, the page cache also uses the mapping's GFP flags for allocating radix tree nodes. It always masked off the __GFP_HIGHMEM flag, and masks off __GFP_ZERO in some paths, but not all. That causes radix tree nodes to be allocated with a NULL list_head, which causes backtraces like: [<ffffff80086f4de0>] __list_del_entry+0x30/0xd0 [<ffffff8008362018>] list_lru_del+0xac/0x1ac [<ffffff800830f04c>] page_cache_tree_insert+0xd8/0x110 The __GFP_DMA and __GFP_DMA32 flags would also be able to sneak through if they are ever used. Fix them all by using GFP_RECLAIM_MASK at the innermost location, and remove it from earlier in the callchain.

[PATCH] drm/amd/display: Disallow enabling CRTC without primary plane with FB

by Harry Wentland

The below commit "drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2" introduces a slight behavioral change to rmfb. Instead of disabling a crtc when the primary plane is disabled, it now preserves it. Since DC is currently not equipped to handle this we need to fail such a commit, otherwise we might see a corrupted screen. This is based on Shirish's previous approach but avoids adding all planes to the new atomic state which leads to a full update in DC for any commit, and is not what we intend. Theoretically DM should be able to deal with states with fully populated planes, even for simple updates, such as cursor updates. This should still be addressed in the future.

[PATCH] btrfs: fix unaligned access in readdir

The last update to readdir introduced a temporary buffer to store the emitted readdir data, but as there are file names of variable length, there's a lot of unaligned access. This was observed on a sparc64 machine: Kernel unaligned access at TPC[102f3080] btrfs_real_readdir+0x51c/0x718 [btrfs] Fixes: 23b5ec74943 ("btrfs: fix readdir deadlock with pagefault") CC: stable(a)vger.kernel.org # 4.14+ Reported-and-tested-by: René Rebe <rene(a)exactcode.com> Signed-off-by: David Sterba <dsterba(a)suse.com> --- fs/btrfs/inode.c | 20 ++++++++++++-------- 1 file changed, 12 insertions(+), 8 deletions(-) diff --git a/fs/btrfs/inode.c b/fs/btrfs/inode.c index e064c49c9a9a..d241285a0d2a 100644 --- a/fs/btrfs/inode.c +++ b/fs/btrfs/inode.c @@ -31,6 +31,7 @@ #include <linux/uio.h> #include <linux/magic.h> #include <linux/iversion.h> +#include <asm/unaligned.h> #include "ctree.h" #include "disk-io.h" #include "transaction.h" @@ -5905,11 +5906,13 @@ static int btrfs_filldir(void *addr, int entries, struct dir_context *ctx) struct dir_entry *entry = addr; char *name = (char *)(entry + 1); - ctx->pos = entry->offset; - if (!dir_emit(ctx, name, entry->name_len, entry->ino, - entry->type)) + ctx->pos = get_unaligned(&entry->offset); + if (!dir_emit(ctx, name, get_unaligned(&entry->name_len), + get_unaligned(&entry->ino), + get_unaligned(&entry->type))) return 1; - addr += sizeof(struct dir_entry) + entry->name_len; + addr += sizeof(struct dir_entry) + + get_unaligned(&entry->name_len); ctx->pos++; } return 0; @@ -5999,14 +6002,15 @@ static int btrfs_real_readdir(struct file *file, struct dir_context *ctx) } entry = addr; - entry->name_len = name_len; + put_unaligned(name_len, &entry->name_len); name_ptr = (char *)(entry + 1); read_extent_buffer(leaf, name_ptr, (unsigned long)(di + 1), name_len); - entry->type = btrfs_filetype_table[btrfs_dir_type(leaf, di)]; + put_unaligned(btrfs_filetype_table[btrfs_dir_type(leaf, di)], + &entry->type); btrfs_dir_item_key_to_cpu(leaf, di, &location); - entry->ino = location.objectid; - entry->offset = found_key.offset; + put_unaligned(location.objectid, &entry->ino); + put_unaligned(found_key.offset, &entry->offset); entries++; addr += sizeof(struct dir_entry) + name_len; total_len += sizeof(struct dir_entry) + name_len; -- 2.16.2
