[alsa-devel] [PATCH] ASoC: wm8904: fix automatic sysclk configuration
by Michael Walle 28 Nov '19

28 Nov '19

The simple-card tries to signal the codec to disable rate constraints, see commit 2458adb8f92a ("SoC: simple-card-utils: set 0Hz to sysclk when shutdown"). This wasn't handled by the codec, instead it would set the FLL frequency to 0Hz which isn't working. Since we don't have any rate constraints just ignore this request.

[alsa-devel] [PATCH v3] ALSA: hda: hdmi - fix regression in connect list handling
by Kai Vehmanen 28 Nov '19

28 Nov '19

Fix regression in how intel_haswell_fixup_connect_list() results are used in hda_read_pin_conn(). Use of snd_hda_get_raw_connections() in hda_read_pin_conn() bypasses the cache and thus also bypasses the overridden pin connection list. On platforms that require the connection list fixup, mux list will be empty and HDMI playback will fail to -EBUSY at open. Fix the regression in hda_read_pinn_conn(). Simplify code as suggested by Takashi Iwai to remove old intel_haswell_fixup_connect_list() and copy the cvt_nid list directly and not use snd_hda_override_conn_list() at all.

[alsa-devel] [PATCH v2 00/12] treewide: break dependencies on x86's RM header
by Sean Christopherson 27 Nov '19

27 Nov '19

x86's asm/realmode.h, which defines low level structures, variables and helpers used to bring up APs during SMP boot, ends up getting included in practically every nook and cranny of the kernel because the address used by ACPI for resuming from S3 also happens to be stored in the real mode header, and ACPI bleeds the dependency into its widely included headers. As a result, modifying realmode.h for even the most trivial change to the boot code triggers a full kernel rebuild, which is frustrating to say the least as it some of the most difficult code to get exactly right *and* is also some of the most functionally isolated code in the kernel. To break the kernel's widespread dependency on realmode.h, add a wrapper in the aforementioned ACPI S3 code to access the real mode header instead of derefencing the header directly in asm/acpi.h and thereby exposing it to the world via linux/acpi.h. v2: - Rebased on tip/x86/cleanups, commit b74374fef924 ("x86/setup: Enhance the comments"). - Use acpi_get_wakeup_address() as new function name. [Boris and Pavel] - Capture acpi_get_wakeup_address() in a local address. [Pavel] - Collect acks. I didn't add Rafael's acks on patches 11 and 12 due to the above changes. - Explicitly call out the removal of <asm/realmode.h> from <asm/acpi.h> in patch 12. [Ingo] - Remove superfluous Fixes: tags. [Ard] Patch Synopsis: - Patches 01-09 fix a variety of build errors that arise when patch 12 drops realmode.h from asm/acpi.h. Most of the errors are quite absurb as they have no relation whatsoever to x86's RM boot code, but occur because realmode.h happens to include asm/io.h. - Patch 10 removes a spurious include of realmode.h from an ACPI header. - Patches 11 and 12 implement the wrapper and move it out of acpi.h. Sean Christopherson (12): x86/efi: Explicitly include realmode.h to handle RM trampoline quirk x86/boot: Explicitly include realmode.h to handle RM reservations x86/ftrace: Explicitly include vmalloc.h for set_vm_flush_reset_perms() x86/kprobes: Explicitly include vmalloc.h for set_vm_flush_reset_perms() perf/x86/intel: Explicitly include asm/io.h to use virt_to_phys() efi/capsule-loader: Explicitly include linux/io.h for page_to_phys() virt: vbox: Explicitly include linux/io.h to pick up various defs vmw_balloon: Explicitly include linux/io.h for virt_to_phys() ASoC: Intel: Skylake: Explicitly include linux/io.h for virt_to_phys() x86/ACPI/sleep: Remove an unnecessary include of asm/realmode.h ACPI/sleep: Convert acpi_wakeup_address into a function x86/ACPI/sleep: Move acpi_get_wakeup_address() into sleep.c, remove <asm/realmode.h> from <asm/acpi.h> arch/ia64/include/asm/acpi.h | 5 ++++- arch/ia64/kernel/acpi.c | 2 -- arch/x86/events/intel/ds.c | 1 + arch/x86/include/asm/acpi.h | 3 +-- arch/x86/kernel/acpi/sleep.c | 11 +++++++++++ arch/x86/kernel/acpi/sleep.h | 2 +- arch/x86/kernel/ftrace.c | 1 + arch/x86/kernel/kprobes/core.c | 1 + arch/x86/kernel/setup.c | 1 + arch/x86/platform/efi/quirks.c | 1 + drivers/acpi/sleep.c | 3 +++ drivers/firmware/efi/capsule-loader.c | 1 + drivers/misc/vmw_balloon.c | 1 + drivers/virt/vboxguest/vboxguest_core.c | 1 + drivers/virt/vboxguest/vboxguest_utils.c | 1 + sound/soc/intel/skylake/skl-sst-cldma.c | 1 + 16 files changed, 30 insertions(+), 6 deletions(-) -- 2.24.0
