Upon closing the file descriptor, the active performance monitor is not stopped. Although all perfmons are destroyed in `vc4_perfmon_close_file()`, the active performance monitor's pointer (`vc4->active_perfmon`) is still retained. If we open a new file descriptor and submit a few jobs with performance monitors, the driver will attempt to stop the active performance monitor using the stale pointer in `vc4->active_perfmon`. However, this pointer is no longer valid because the previous process has already terminated, and all performance monitors associated with it have been destroyed and freed. To fix this, when the active performance monitor belongs to a given process, explicitly stop it before destroying and freeing it.

The only user (the mesa gallium driver) is already assuming explicit synchronization and doing the export/import dance on shared BOs. The only reason we were registering ourselves as writers on external BOs is because Xe, which was the reference back when we developed Panthor, was doing so. Turns out Xe was wrong, and we really want bookkeep on all registered fences, so userspace can explicitly upgrade those to read/write when needed.

If deferred operations are pending, we want to wait for those to land before declaring the queue blocked on a SYNC_WAIT. We need this to deal with the case where the sync object is signalled through a deferred SYNC_{ADD,SET} from the same queue. If we don't do that and the group gets scheduled out before the deferred SYNC_{SET,ADD} is executed, we'll end up with a timeout, because no external SYNC_{SET,ADD} will make the scheduler reconsider the group for execution.

The isomorphism neg_if_exp negates the test of a ?: conditional, making it unnecessary to have an explicit case for a negated test with the branches inverted. At the same time, we can disable neg_if_exp in cases where a different API function may be more suitable for a negated test. Finally, in the non-patch cases, E matches an expression with parentheses around it, so there is no need to mention () explicitly in the pattern. The () are still needed in the patch cases, because we want to drop them, if they are present. Signed-off-by:

The parentheses are only needed if there is a disjunction, ie a set of possible changes. If there is only one pattern, we can remove these parentheses. Just like the format: - x + y not: ( - x + y ) Signed-off-by:

As done with str_true_false(), add checks for str_false_true() opportunities. A simple test can find over 9 cases currently exist in the tree. Signed-off-by:

Pull x86 kvm updates from Paolo Bonzini: "x86: - KVM currently invalidates the entirety of the page tables, not just those for the memslot being touched, when a memslot is moved or deleted. This does not traditionally have particularly noticeable overhead, but Intel's TDX will require the guest to re-accept private pages if they are dropped from the secure EPT, which is a non starter. Actually, the only reason why this is not already being done is a bug which was never fully investigated and caused VM instability with assigned GeForce GPUs, so allow userspace to opt into the new behavior. - Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10 functionality that is on the horizon) - Rework common MSR handling code to suppress errors on userspace accesses to unsupported-but-advertised MSRs This will allow removing (almost?) all of KVM's exemptio...

Pull module updates from Luis Chamberlain: "There are a few fixes / cleanups from Vincent, Chunhui, and Petr, but the most important part of this pull request is the Rust community stepping up to help maintain both C / Rust code for future Rust module support. We grow the set of modules maintainers by three now, and with this hope to scale to help address what's needed to properly support future Rust module support. A lot of exciting stuff coming in future kernel releases. This has been on linux-next for ~ 3 weeks now with no issues" * tag 'modules-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: module: Refine kmemleak scanned areas module: abort module loading when sysfs setup suffer errors MAINTAINERS: scale modules with more reviewers module: Clean up the description of MODULE_SIG_<type> module: Split modules_install compression and in-kernel decompression
