sm8250 faces the same problem with its Energy Model as sdm845. The energy cost of LITTLE cores is reported to be higher than medium or big cores EM computes the energy with formula: energy = OPP's cost / maximum cpu capacity * utilization On v6.4-rc6 we have: max capacity of CPU0 = 284 capacity of CPU0's OPP(1612800 Hz) = 253 cost of CPU0's OPP(1612800 Hz) = 191704 max capacity of CPU4 = 871 capacity of CPU4's OPP(710400 Hz) = 255 cost of CPU4's OPP(710400 Hz) = 343217 Both OPPs have almost the same compute capacity but the estimated energy per unit of utilization will be estimated to: energy CPU0 = 191704 / 284 * 1 = 675 energy CPU4 = 343217 / 871 * 1 = 394 EM estimates that little CPU0 will consume 71% more than medium CPU4 for the same compute capacity. According to [1], little consumes 25% less than medium core for Coremark benchmark at those OPPs for the same duration. Set the dynamic-power-coefficient of CPU0-3 to 105 to fix the energy model for little CPUs.

The Linux typec_mux implementation required that a property named "svid" was present in the remote node of the of_graph for a match to be found. With the introduction of commit '4aebc4f8 ("usb: typec: mux: Clean up mux_fwnode_match()")', the implementation is aligned with the binding and this property can be dropped - and the associated DeviceTree validation warning resolved.

We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this. At some point "perverse sense of curiosity" turns into just a cold dark place filled with sadness and despair. Repeats: 80e62bc8 ("MAINTAINERS: re-sort all entries and fields") Signed-off-by:

But the same code path is also used by the crash utility. If the CPU which panics is not the boot CPU then it sends an INIT IPI to the boot CPU which resets the machine. Prevent this by validating that the CPU which runs the stop mechanism is the boot CPU.

Suren Baghdasaryan authored
When forking a child process, the parent write-protects anonymous pages and COW-shares them with the child being forked using copy_present_pte(). We must not take any concurrent page faults on the source vma's as they are being processed, as we expect both the vma and the pte's behind it to be stable. For example, the anon_vma_fork() expects the parents vma->anon_vma to not change during the vma copy. A concurrent page fault on a page newly marked read-only by the page copy might trigger wp_page_copy() and a anon_vma_prepare(vma) on the source vma, defeating the anon_vma_clone() that wasn't done because the parent vma originally didn't have an anon_vma, but we now might end up copying a pte entry for a page that has one. Before the per-vma lock based changes, the mmap_lock guaranteed exclusion with concurrent page faults. But now we need to do a vma_start_write() to make sure no concurrent faults happen on this vma while it is being processed. This fix can potentially regress some fork-heavy workloads. Kernel build time did not show noticeable regression on a 56-core machine while a stress test mapping 10000 VMAs and forking 5000 times in a tight loop shows ~5% regression. If such fork time regression is unacceptable, disabling CONFIG_PER_VMA_LOCK should restore its performance. Further optimizations are possible if this regression proves to be problematic.
