[PATCH] ALSA: oxfw: fix functioal regression for silence in Apogee Duet FireWire

by Takashi Sakamoto

OXFW 971 has no function to use the value in syt field of received isochronous packet for playback timing generation. In kernel prepatch for v5.14, ALSA OXFW driver got change to send NO_INFO value in the field instead of actual timing value. The change brings Apogee Duet FireWire to generate no playback sound, while output meter moves. As long as I investigate, _any_ value in the syt field takes the device to generate sound. It's reasonable to think that the device just ignores data blocks in packet with NO_INFO value in its syt field for audio data processing. This commit adds a new flag for the quirk to fix regression.

[PATCH 3/3] x86/reboot: Limit Dell Optiplex 990 quirk to early BIOS versions

by Paul Gortmaker

When this platform was relatively new in November 2011, with early BIOS revisions, a reboot quirk was added in commit 6be30bb7d750 ("x86/reboot: Blacklist Dell OptiPlex 990 known to require PCI reboot") However, this quirk (and several others) are open-ended to all BIOS versions and left no automatic expiry if/when the system BIOS fixed the issue, meaning that nobody is likely to come along and re-test. What is really problematic with using PCI reboot as this quirk does, is that it causes this platform to do a full power down, wait one second, and then power back on. This is less than ideal if one is using it for boot testing and/or bisecting kernels when legacy rotating hard disks are installed. It was only by chance that I saw the quirk in dmesg - and then disabled it to find that it wasn't required anymore (BIOS A24), and a default reboot would work fine without the "harshness" of power cycling the machine (and disks) down and up like the PCI reboot does. Doing a bit more research, it seems that the "newest" BIOS for which the issue was reported[1] was version A06, however Dell[2] seemed to suggest only up to and including version A05, with the A06 having a large number of fixes[3] listed. As is typical with a new platform, the initial BIOS updates come frequently and then taper off (and in this case, with a revival for CPU CVEs); a search for O990-A<ver>.exe reveals the following dates: A02 16 Mar 2011 A03 11 May 2011 A06 14 Sep 2011 A07 24 Oct 2011 A10 08 Dec 2011 A14 06 Sep 2012 A16 15 Oct 2012 A18 30 Sep 2013 A19 23 Sep 2015 A20 02 Jun 2017 A23 07 Mar 2018 A24 21 Aug 2018 While I'm not going to flash and test each of the above, it would seem likely that the issue was contained within A0x BIOS versions, given the dates above and the dates of issue reports[4] from distros. So rather than just throw out the quirk entirely, I've limited the scope to just those early BIOS versions, in case people are still running systems from 2011 with the original as-shipped early A0x BIOS versions.

[PATCH v4 2/2] bus: mhi: Fix MHI DMA structure endianness

by Paul Davey

The MHI driver does not work on big endian architectures. The controller never transitions into mission mode. This appears to be due to the modem device expecting the various contexts and transfer rings to have fields in little endian order in memory, but the driver constructs them in native endianness. Fix MHI event, channel and command contexts and TRE handling macros to use explicit conversion to little endian. Mark fields in relevant structures as little endian to document this requirement. Fixes: a6e2e3522f29 ("bus: mhi: core: Add support for PM state transitions") Fixes: 6cd330ae76ff ("bus: mhi: core: Add support for ringing channel/event ring doorbells") Cc: stable(a)vger.kernel.org Signed-off-by: Paul Davey <paul.davey(a)alliedtelesis.co.nz> --- drivers/bus/mhi/core/debugfs.c | 26 +++---- drivers/bus/mhi/core/init.c | 36 +++++----- drivers/bus/mhi/core/internal.h | 119 ++++++++++++++++---------------- drivers/bus/mhi/core/main.c | 22 +++--- drivers/bus/mhi/core/pm.c | 4 +- 5 files changed, 104 insertions(+), 103 deletions(-) diff --git a/drivers/bus/mhi/core/debugfs.c b/drivers/bus/mhi/core/debugfs.c index 858d7516410b..d818586c229d 100644 --- a/drivers/bus/mhi/core/debugfs.c +++ b/drivers/bus/mhi/core/debugfs.c @@ -60,16 +60,16 @@ static int mhi_debugfs_events_show(struct seq_file *m, void *d) } seq_printf(m, "Index: %d intmod count: %lu time: %lu", - i, (er_ctxt->intmod & EV_CTX_INTMODC_MASK) >> + i, (le32_to_cpu(er_ctxt->intmod) & EV_CTX_INTMODC_MASK) >> EV_CTX_INTMODC_SHIFT, - (er_ctxt->intmod & EV_CTX_INTMODT_MASK) >> + (le32_to_cpu(er_ctxt->intmod) & EV_CTX_INTMODT_MASK) >> EV_CTX_INTMODT_SHIFT);

[PATCH v4 1/2] bus: mhi: Fix pm_state conversion to string

by Paul Davey

On big endian architectures the mhi debugfs files which report pm state give "Invalid State" for all states. This is caused by using find_last_bit which takes an unsigned long* while the state is passed in as an enum mhi_pm_state which will be of int size. Fix by using __fls to pass the value of state instead of find_last_bit.

[for-linus][PATCH 5/7] tracing: define needed config DYNAMIC_FTRACE_WITH_ARGS

by Steven Rostedt

From: Lukas Bulwahn <lukas.bulwahn(a)gmail.com> Commit 2860cd8a2353 ("livepatch: Use the default ftrace_ops instead of REGS when ARGS is available") intends to enable config LIVEPATCH when ftrace with ARGS is available. However, the chain of configs to enable LIVEPATCH is incomplete, as HAVE_DYNAMIC_FTRACE_WITH_ARGS is available, but the definition of DYNAMIC_FTRACE_WITH_ARGS, combining DYNAMIC_FTRACE and HAVE_DYNAMIC_FTRACE_WITH_ARGS, needed to enable LIVEPATCH, is missing in the commit. Fortunately, ./scripts/checkkconfigsymbols.py detects this and warns: DYNAMIC_FTRACE_WITH_ARGS Referencing files: kernel/livepatch/Kconfig So, define the config DYNAMIC_FTRACE_WITH_ARGS analogously to the already existing similar configs, DYNAMIC_FTRACE_WITH_REGS and DYNAMIC_FTRACE_WITH_DIRECT_CALLS, in ./kernel/trace/Kconfig to connect the chain of configs.
