2023-06-01mtdchar: mark bits of ioctl handler noinlineArnd Bergmann
The addition of the mtdchar_read_ioctl() function caused the stack usage of mtdchar_ioctl() to grow beyond the warning limit on 32-bit architectures with gcc-13: drivers/mtd/mtdchar.c: In function 'mtdchar_ioctl': drivers/mtd/mtdchar.c:1229:1: error: the frame size of 1488 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Mark both the read and write portions as noinline_for_stack to ensure they don't get inlined and use separate stack slots to reduce the maximum usage, both in the mtdchar_ioctl() and combined with any of its callees.

2023-06-01net: dsa: mv88e6xxx: Increase wait after reset deactivationAndreas Svensson
A switch held in reset by default needs to wait longer until we can reliably detect it. An issue was observed when testing on the Marvell 88E6393X (Link Street). The driver failed to detect the switch on some upstarts. Increasing the wait time after reset deactivation solves this issue. The updated wait time is now also the same as the wait time in the mv88e6xxx_hardware_reset function.

2023-06-01wifi: rtw89: correct PS calculation for SUPPORTS_DYNAMIC_PSPing-Ke Shih
This driver relies on IEEE80211_CONF_PS of hw->conf.flags to turn off PS or turn on dynamic PS controlled by driver and firmware. Though this would be incorrect, it did work before because the flag is always recalculated until the commit 28977e790b5d ("wifi: mac80211: skip powersave recalc if driver SUPPORTS_DYNAMIC_PS") is introduced by kernel 5.20 to skip to recalculate IEEE80211_CONF_PS of hw->conf.flags if driver sets SUPPORTS_DYNAMIC_PS. Correct this by doing recalculation while BSS_CHANGED_PS is changed and interface is added or removed. For now, it is allowed to enter PS only if single one station vif is working, and it could possible to have PS per vif after firmware can support it. Without this fix, driver doesn't enter PS anymore that causes higher power consumption.

That is, only when report size is a sub-multiple of the OA buffer size can we be certain that reports will land at the same place each time in the OA buffer (after rewind).

2023-05-31net/mlx5: Fix setting of irq->map.index for static IRQ caseNiklas Schnelle
When dynamic IRQ allocation is not supported all IRQs are allocated up front in mlx5_irq_table_create() instead of dynamically as part of mlx5_irq_alloc(). In the latter dynamic case irq->map.index is set via the mapping returned by pci_msix_alloc_irq_at(). In the static case and prior to commit 1da438c0ae02 ("net/mlx5: Fix indexing of mlx5_irq") irq->map.index was set in mlx5_irq_alloc() twice once initially to 0 and then to the requested index before storing in the xarray. After this commit it is only set to 0 which breaks all other IRQ mappings. Fix this by setting irq->map.index to the requested index together with irq->map.virq and improve the related comment to make it clearer which cases it deals with.

2023-05-31net/mlx5: Remove rmap also in case dynamic MSIX not supportedShay Drory
mlx5 add IRQs to rmap upon MSIX request, and mlx5 remove rmap from MSIX only if msi_map.index is populated. However, msi_map.index is populated only when dynamic MSIX is supported. This results in freeing IRQs without removing them from rmap, which triggers the bellow WARN_ON[1]. rmap is a feature which have no relation to dynamic MSIX. Hence, remove the check of msi_map.index when removing IRQ from rmap.

2023-05-31drivers: base: cacheinfo: Update cpu_map_populated during CPU HotplugK Prateek Nayak
Until commit 5c2712387d48 ("cacheinfo: Fix LLC is not exported through sysfs"), cacheinfo called populate_cache_leaves() for CPU coming online which let the arch specific functions handle (at least on x86) populating the shared_cpu_map. However, with the changes in the aforementioned commit, populate_cache_leaves() is not called when a CPU comes online as a result of hotplug since last_level_cache_is_valid() returns true as the cacheinfo data is not discarded. The CPU coming online is not present in shared_cpu_map, however, it will not be added since the cpu_cacheinfo->cpu_map_populated flag is set (it is set in populate_cache_leaves() when cacheinfo is first populated for x86) This can lead to inconsistencies in the shared_cpu_map when an offlined CPU comes online again. Example below depicts the inconsistency in the shared_cpu_list in cacheinfo when CPU8 is offlined and onlined again on a 3rd Generation EPYC processor: # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143 # echo 0 > /sys/devices/system/cpu/cpu8/online # echo 1 > /sys/devices/system/cpu/cpu8/online # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8 # cat /sys/devices/system/cpu/cpu136/cache/index0/shared_cpu_list 136 # cat /sys/devices/system/cpu/cpu136/cache/index3/shared_cpu_list 9-15,136-143 Clear the flag when the CPU is removed from shared_cpu_map when cache_shared_cpu_map_remove() is called during CPU hotplug. This will allow cache_shared_cpu_map_setup() to add the CPU coming back online in the shared_cpu_map. Set the flag again when the shared_cpu_map is setup. Following are results of performing the same test as described above with the changes: # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143 # echo 0 > /sys/devices/system/cpu/cpu8/online # echo 1 > /sys/devices/system/cpu/cpu8/online # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143 # cat /sys/devices/system/cpu/cpu136/cache/index0/shared_cpu_list 8,136 # cat /sys/devices/system/cpu/cpu136/cache/index3/shared_cpu_list 8-15,136-143 Fixes: 5c2712387d48 ("cacheinfo: Fix LLC is not exported through sysfs") Signed-off-by: K Prateek Nayak <kprateek.nayak@amd.com> Reviewed-by: Yicong Yang <yangyicong@hisilicon.com> Reviewed-by: Sudeep Holla <sudeep.holla@arm.com> Link: https://lore.kernel.org/r/20230508084115.1157-3-kprateek.nayak@amd.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2023-05-31drivers: base: cacheinfo: Fix shared_cpu_map changes in event of CPU hotplugK Prateek Nayak
While building the shared_cpu_map, check if the cache level and cache type matches. On certain systems that build the cache topology based on the instance ID, there are cases where the same ID may repeat across multiple cache levels, leading inaccurate topology. In event of CPU offlining, the cache_shared_cpu_map_remove() does not consider if IDs at same level are being compared. As a result, when same IDs repeat across different cache levels, the CPU going offline is not removed from all the shared_cpu_map. Below is the output of cache topology of CPU8 and it's SMT sibling after CPU8 is offlined on a dual socket 3rd Generation AMD EPYC processor (2 x 64C/128T) running kernel release v6.3: # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143 # echo 0 > /sys/devices/system/cpu/cpu8/online # for i in /sys/devices/system/cpu/cpu136/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu136/cache/index0/shared_cpu_list: 136 /sys/devices/system/cpu/cpu136/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu136/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu136/cache/index3/shared_cpu_list: 9-15,136-143 CPU8 is removed from index0 (L1i) but remains in the shared_cpu_list of index1 (L1d) and index2 (L2). Since L1i, L1d, and L2 are shared by the SMT siblings, and they have the same cache instance ID, CPU 2 is only removed from the first index with matching ID which is index1 (L1i) in this case. With this fix, the results are as expected when performing the same experiment on the same system: # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143 # echo 0 > /sys/devices/system/cpu/cpu8/online # for i in /sys/devices/system/cpu/cpu136/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu136/cache/index0/shared_cpu_list: 136 /sys/devices/system/cpu/cpu136/cache/index1/shared_cpu_list: 136 /sys/devices/system/cpu/cpu136/cache/index2/shared_cpu_list: 136 /sys/devices/system/cpu/cpu136/cache/index3/shared_cpu_list: 9-15,136-143 When rebuilding topology, the same problem appears as cache_shared_cpu_map_setup() implements a similar logic. Consider the same 3rd Generation EPYC processor: CPUs in Core 1, that share the L1 and L2 caches, have L1 and L2 instance ID as 1. For all the CPUs on the second chiplet, the L3 ID is also 1 leading to grouping on CPUs from Core 1 (1, 17) and the entire second chiplet (8-15, 24-31) as CPUs sharing one cache domain. This went undetected since x86 processors depended on arch specific populate_cache_leaves() method to repopulate the shared_cpus_map when CPU came back online until kernel release v6.3-rc5.

2023-05-31HID: logitech-hidpp: Handle timeout differently from busyBastien Nocera
If an attempt at contacting a receiver or a device fails because the receiver or device never responds, don't restart the communication, only restart it if the receiver or device answers that it's busy, as originally intended. This was the behaviour on communication timeout before commit 586e8fede795 ("HID: logitech-hidpp: Retry commands when device is busy"). This fixes some overly long waits in a critical path on boot, when checking whether the device is connected by getting its HID++ version.

2023-05-30nvme: improve handling of long keep alivesUday Shankar
Upon keep alive completion, nvme_keep_alive_work is scheduled with the same delay every time. If keep alive commands are completing slowly, this may cause a keep alive timeout. The following trace illustrates the issue, taking KATO = 8 and TBKAS off for simplicity: 1. t = 0: run nvme_keep_alive_work, send keep alive 2. t = ε: keep alive reaches controller, controller restarts its keep alive timer 3. t = 4: host receives keep alive completion, schedules nvme_keep_alive_work with delay 4 4. t = 8: run nvme_keep_alive_work, send keep alive Here, a keep alive having RTT of 4 causes a delay of at least 8 - ε between the controller receiving successive keep alives. With ε small, the controller is likely to detect a keep alive timeout. Fix this by calculating the RTT of the keep alive command, and adjusting the scheduling delay of the next keep alive work accordingly.

2023-05-30fbdev: bw2: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
