[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. Background: Directory /sys/kernel/debug/kprobes is created by debugfs_create_dir() which sets the mode bits to rwxr-xr-x. Maybe change that to use the parent's directory mode bits instead?

[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.
