AOSP's `netd` process fails to start on Android S: E ClatdController: getClatEgress4MapFd() failure: Operation not permitted I netd : Initializing ClatdController: 410us E netd : Failed to start trafficcontroller: (Status[code: 1, msg: "Pinned map not accessible or does not exist: (/sys/fs/bpf/map_netd_cookie_tag_map): Operation not permitted"]) E netd : CRITICAL: sleeping 60 seconds, netd exiting with failure, crash loop likely!

Android nowadays (for a couple years already) requires AIO for at least its `adb` "Android Debug Bridge" [1]. Without this config option (`default y`) it simply refuses start, making users unable to connect to their phone for debugging purposes when using these kernel fragments.

The family and device comparisons were using memcmp(), but this could lead to Out-of-bounds reads when the length was larger than the buffers being compared. Since these appear to always be NUL-terminated strings, just use strcmp() instead. This was found with Clang under LTO: [ 92.405851][ T1] kernel BUG at lib/string_helpers.c:980! ...

sc7180 blow fuses got slightly chances to hit qfprom_reg_write timeout. Current timeout is simply too low. Since blowing fuses is a very rare operation, so the risk associated with overestimating this number is low. Increase fuse blow timeout from 1ms to 10ms. Reviewed-by:

Delta TN48M switch has an onboard Lattice CPLD that is used as a GPIO expander. The CPLD provides 12 pins in total on the TN48M, but on more advanced switch models it provides up to 192 pins, so the driver is extendable to support more switches. Reviewed-by:

Delta TN48M switches have a Lattice CPLD that serves multiple purposes including being a GPIO expander. So, lets use the simple I2C MFD driver to provide the MFD core. Also add a virtual symbol which pulls in the simple-mfd-i2c driver and provide a common symbol on which the subdevice drivers can depend on. Acked-for-MFD-by:

Since MMC core handles runtime PM reference counting, we can avoid doing redundant runtime PM work in the driver. That means the only thing commit 5b4258f6 ("misc: rtsx: rts5249 support runtime PM") misses is to always enable runtime PM, to let its parent driver enable ASPM in the runtime idle routine. Fixes: 7499b529 ("mmc: rtsx: Use pm_runtime_{get,put}() to handle runtime PM") Reviewed-by:

FSI_SBEFIFO_READ_TIMEOUT_SECONDS ioctl sets the read timeout (in seconds) for the response received by sbefifo device from sbe. The timeout affects only the read operation on current sbefifo device fd. Certain SBE operations can take long time to complete and the default timeout of 10 seconds might not be sufficient to start receiving response from SBE. In such cases, allow the timeout to be set to the maximum of 120 seconds. The kernel does not contain the definition of the various SBE operations, so we must expose an interface to userspace to set the timeout for the given operation. Signed-off-by:

For some of the chip-ops where sbe needs to collect trace information, sbe can take a long time (>30s) to respond. Currently these chip-ops will timeout as the start of response timeout defaults to 10s. Instead of default value, use specified value. The require timeout value will be set using ioctl.
