2022-03-07perf evsel: Add error message for unsupported branch stack casesJames Clark1-0/+4
EOPNOTSUPP is a possible return value when branch stacks are requested but they aren't enabled in the kernel or hardware. It's also returned if they aren't supported on the specific event type. The currently printed error message about sampling/overflow-interrupts is not correct in this case. Add a check for branch stacks before sample_period is checked because sample_period is also set (to the default value) when using branch stacks. Before this change (when branch stacks aren't supported): perf record -j any Error: cycles: PMU Hardware doesn't support sampling/overflow-interrupts. Try 'perf stat' After this change: perf record -j any Error: cycles: PMU Hardware or event type doesn't support branch stack sampling.

With FEAT_ECV and the 1GHz counter, it is pretty likely that the event stream divider doesn't fit in the field that holds the divider value (we only have 4 bits to describe counter bits [15:0] Thankfully, FEAT_ECV also provides a scaling mechanism to switch the field to cover counter bits [23:8] instead.

2022-03-07clocksource/drivers/exynos_mct: Handle DTS with higher number of interruptsKrzysztof Kozlowski1-1/+9
The driver statically defines maximum number of interrupts it can handle, however it does not respect that limit when configuring them. When provided with a DTS with more interrupts than assumed, the driver will overwrite static array mct_irqs leading to silent memory corruption. Validate the interrupts coming from DTS to avoid this. This does not change the fact that such DTS might not boot at all, because it is simply incompatible, however at least some warning will be printed.

2022-03-07media: i2c: max2175: Use rbtree rather than flat register cacheMark Brown1-1/+1
The max2175 uses a flat register cache but supplies only a single default value and has many volatile registers. This is a poor fit for a flat cache since the cache will assume a default of zero for any register not yet written which can lead to bugs for example when regmap_update_bits() suppresses a noop write. A rbtree cache is a much better fit, this will only cache default values and values that have been written to the device with any reads of uncached values going to the hardware. Convert the driver to use a rbtree cache. Since the device is controlled via I2C the cost of manging the rbtree should be immaterial compared to the cost of accessing the device.

2022-03-07fuse: fix pipe buffer lifetime for direct_ioMiklos Szeredi3-1/+13
In FOPEN_DIRECT_IO mode, fuse_file_write_iter() calls fuse_direct_write_iter(), which normally calls fuse_direct_io(), which then imports the write buffer with fuse_get_user_pages(), which uses iov_iter_get_pages() to grab references to userspace pages instead of actually copying memory. On the filesystem device side, these pages can then either be read to userspace (via fuse_dev_read()), or splice()d over into a pipe using fuse_dev_splice_read() as pipe buffers with &nosteal_pipe_buf_ops. This is wrong because after fuse_dev_do_read() unlocks the FUSE request, the userspace filesystem can mark the request as completed, causing write() to return. At that point, the userspace filesystem should no longer have access to the pipe buffer. Fix by copying pages coming from the user address space to new pipe buffers.
