2024-09-12erofs: allocate more short-lived pages from reserved pool firstChunhai Guo
This patch aims to allocate bvpages and short-lived compressed pages from the reserved pool first. After applying this patch, there are three benefits. 1. It reduces the page allocation time. The bvpages and short-lived compressed pages account for about 4% of the pages allocated from the system in the multi-app launch benchmarks [1]. It reduces the page allocation time accordingly and lowers the likelihood of blockage by page allocation in low memory scenarios. 2. The pages in the reserved pool will be allocated on demand. Currently, bvpages and short-lived compressed pages are short-lived pages allocated from the system, and the pages in the reserved pool all originate from short-lived pages. Consequently, the number of reserved pool pages will increase to z_erofs_rsv_nrpages over time. With this patch, all short-lived pages are allocated from the reserved pool first, so the number of reserved pool pages will only increase when there are not enough pages. Thus, even if z_erofs_rsv_nrpages is set to a large number for specific reasons, the actual number of reserved pool pages may remain low as per demand. In the multi-app launch benchmarks [1], z_erofs_rsv_nrpages is set at 256, while the number of reserved pool pages remains below 64. 3. When erofs cache decompression is disabled (EROFS_ZIP_CACHE_DISABLED), all pages will *only* be allocated from the reserved pool for erofs. This will significantly reduce the memory pressure from erofs. [1] For additional details on the multi-app launch benchmarks, please refer to commit 0f6273ab4637 ("erofs: add a reserved buffer pool for lz4 decompression").

2024-09-12block: fix potential invalid pointer dereference in blk_add_partitionRiyan Dhiman
The blk_add_partition() function initially used a single if-condition (IS_ERR(part)) to check for errors when adding a partition. This was modified to handle the specific case of -ENXIO separately, allowing the function to proceed without logging the error in this case. However, this change unintentionally left a path where md_autodetect_dev() could be called without confirming that part is a valid pointer. This commit separates the error handling logic by splitting the initial if-condition, improving code readability and handling specific error scenarios explicitly. The function now distinguishes the general error case from -ENXIO without altering the existing behavior of md_autodetect_dev() calls.

2024-09-12drm/xe/client: fix deadlock in show_meminfo()Matthew Auld
There is a real deadlock as well as sleeping in atomic() bug in here, if the bo put happens to be the last ref, since bo destruction wants to grab the same spinlock and sleeping locks. Fix that by dropping the ref using xe_bo_put_deferred(), and moving the final commit outside of the lock. Dropping the lock around the put is tricky since the bo can go out of scope and delete itself from the list, making it difficult to navigate to the next list entry.

Also a new feature KVM_FEATURE_VIRT_EXTIOI is added which can be set from user space.

We can set which PMU CSRs are used by the guest by writing to the GCFG register [24:26] bits. On KVM side: - Save the host PMU CSRs into structure kvm_context. - If the host supports the PMU feature. - When entering guest mode, save the host PMU CSRs and restore the guest PMU CSRs. - When exiting guest mode, save the guest PMU CSRs and restore the host PMU CSRs.

2024-09-12PCI: Fix potential deadlock in pcim_intx()Philipp Stanner
25216afc9db5 ("PCI: Add managed pcim_intx()") moved the allocation step for pci_intx()'s device resource from pcim_enable_device() to pcim_intx(). As before, pcim_enable_device() sets pci_dev.is_managed to true; and it is never set to false again. Due to the lifecycle of a struct pci_dev, it can happen that a second driver obtains the same pci_dev after a first driver ran. If one driver uses pcim_enable_device() and the other doesn't, this causes the other driver to run into managed pcim_intx(), which will try to allocate when called for the first time. Allocations might sleep, so calling pci_intx() while holding spinlocks becomes then invalid, which causes lockdep warnings and could cause deadlocks: ======================================================== WARNING: possible irq lock inversion dependency detected 6.11.0-rc6+ #59 Tainted: G W -------------------------------------------------------- CPU 0/KVM/1537 just changed the state of lock: ffffa0f0cff965f0 (&vdev->irqlock){-...}-{2:2}, at: vfio_intx_handler+0x21/0xd0 [vfio_pci_core] but this lock took another, HARDIRQ-unsafe lock in the past: (fs_reclaim){+.+.}-{0:0} and interrupts could create inverse lock ordering between them. other info that might help us debug this: Possible interrupt unsafe locking scenario: CPU0 CPU1 ---- ---- lock(fs_reclaim); local_irq_disable(); lock(&vdev->irqlock); lock(fs_reclaim); <Interrupt> lock(&vdev->irqlock); *** DEADLOCK *** Have pcim_enable_device()'s release function, pcim_disable_device(), set pci_dev.is_managed to false so that subsequent drivers using the same struct pci_dev do not implicitly run into managed code.

2024-09-12erofs: sunset unneeded NOFAILsGao Xiang
With iterative development, our codebase can now deal with compressed buffer misses properly if both in-place I/O and compressed buffer allocation fail. Note that if readahead fails (with non-uptodate folios), the original request will then fall back to synchronous read, and `.read_folio()` should return appropriate errnos; otherwise -EIO will be passed to user space, which is unexpected. To simplify rarely encountered failure paths, a mimic decompression will be just used. Before that, failure reasons are recorded in compressed_bvecs[] and they also act as placeholders to avoid in-place pages. They will be parsed just before decompression and then pass back to `.read_folio()`.

Displays the query (fc=0) and query authentication information (fc=127) as binary in sysfs per CPACF instruction. Files are located in /sys/devices/system/cpu/cpacf/. These information can be fetched via asm already except for PCKMO because this instruction is privileged. To offer a unified interface all CPACF instructions will have this information displayed in sysfs in files <instruction>_query_raw and <instruction>_query_auth_info_raw. A new tool introduced into s390-tools called cpacfinfo will use this information to convert and display in human readable form.

2024-09-12HID: i2c-hid: ensure various commands do not interfere with each otherDmitry Torokhov
i2c-hid uses 2 shared buffers: command and "raw" input buffer for sending requests to peripherals and read data from peripherals when executing variety of commands. Such commands include reading of HID registers, requesting particular power mode, getting and setting reports and so on. Because all such requests use the same 2 buffers they should not execute simultaneously. Fix this by introducing "cmd_lock" mutex and acquire it whenever we needs to access ihid->cmdbuf or idid->rawbuf.
