[PATCH v2 2/2] mwifiex: Try waking the firmware until we get an interrupt

by Jonas Dreßler

It seems that the firmware of the 88W8897 card sometimes ignores or misses when we try to wake it up by writing to the firmware status register. This leads to the firmware wakeup timeout expiring and the driver resetting the card because we assume the firmware has hung up or crashed (unfortunately that's not unlikely with this card). Turns out that most of the time the firmware actually didn't hang up, but simply "missed" our wakeup request and didn't send us an AWAKE event. Trying again to read the firmware status register after a short timeout usually makes the firmware wake up as expected, so add a small retry loop to mwifiex_pm_wakeup_card() that looks at the interrupt status to check whether the card woke up. The number of tries and timeout lengths for this were determined experimentally: The firmware usually takes about 500 us to wake up after we attempt to read the status register. In some cases where the firmware is very busy (for example while doing a bluetooth scan) it might even miss our requests for multiple milliseconds, which is why after 15 tries the waiting time gets increased to 10 ms. The maximum number of tries it took to wake the firmware when testing this was around 20, so a maximum number of 50 tries should give us plenty of safety margin. A good reproducer for this issue is letting the firmware sleep and wake up in very short intervals, for example by pinging a device on the network every 0.1 seconds.

FAILED: patch "[PATCH] KVM: rseq: Update rseq when processing NOTIFY_RESUME on xfer" failed to apply to 5.10-stable tree

The patch below does not apply to the 5.10-stable tree.

While the task cannot be in an rseq critical section as the KVM path is reachable only by via ioctl(KVM_RUN), the side effects that apply to rseq outside of a critical section still apply, e.g. the current CPU needs to be updated if the task is migrated. Clearing TIF_NOTIFY_RESUME without informing rseq can lead to segfaults and other badness in userspace VMMs that use rseq in combination with KVM, e.g. due to the CPU ID being stale after task migration.

[PATCH v4.4 v4.9 v4.14] arm64: Extend workaround for erratum 1024718 to all versions of Cortex-A55

by Nanyong Sun

From: Suzuki K Poulose <suzuki.poulose(a)arm.com> commit c0b15c25d25171db4b70cc0b7dbc1130ee94017d upstream. The erratum 1024718 affects Cortex-A55 r0p0 to r2p0. However we apply the work around for r0p0 - r1p0. Unfortunately this won't be fixed for the future revisions for the CPU. Thus extend the work around for all versions of A55, to cover for r2p0 and any future revisions.

backport commit ("c739b17a715c net: stmmac: don't attach interface until resume finishes") to linux-5.4-stable

by Macpaul Lin

Hi reviewers, I suggest to backport commit "c739b17a715c net: stmmac: don't attach interface until resume finishes" to linux-5.4 stable tree. This patch fix resume issue by deferring netif_device_attach(). However, the patch cannot be cherry-pick directly on to stable-5.4. A slightly change to the origin patch is required. I'd like to provide the modification to stable-5.4 if it is needed. commit: c739b17a715c6a850477189fb7c5f9a6af74f4bb subject: net: stmmac: don't attach interface until resume finishes kernel version to apply to: Linux-5.4 Thanks.
