On 32-bit architectures comparing a resource against a value larger than U32_MAX can cause a warning: drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:1344:18: error: result of comparison of constant 4294967296 with expression of type 'resource_size_t' (aka 'unsigned int') is always false [-Werror,-Wtautological-constant-out-of-range-compare] res->start > 0x100000000ull) ~~~~~~~~~~ ^ ~~~~~~~~~~~~~~ As gcc does not warn about this in dead code, add an IS_ENABLED() check at the start of the function.

Retry faults are delegated to soft IH ring and then processed by deferred worker. Current soft IH ring size PAGE_SIZE can store 128 entries, which may overflow and drop retry faults, causes HW stucks because the retry fault is not recovered. Increase soft IH ring size to 8KB, enough to store 256 CAM entries because we clear the CAM entry after handling the retry fault from soft ring.

2023-07-12perf: RISC-V: Remove PERF_HES_STOPPED flag checking in riscv_pmu_start()Eric Lin
Since commit 096b52fd2bb4 ("perf: RISC-V: throttle perf events") the perf_sample_event_took() function was added to report time spent in overflow interrupts. If the interrupt takes too long, the perf framework will lower the sysctl_perf_event_sample_rate and max_samples_per_tick. When hwc->interrupts is larger than max_samples_per_tick, the hwc->interrupts will be set to MAX_INTERRUPTS, and events will be throttled within the __perf_event_account_interrupt() function. However, the RISC-V PMU driver doesn't call riscv_pmu_stop() to update the PERF_HES_STOPPED flag after perf_event_overflow() in pmu_sbi_ovf_handler() function to avoid throttling. When the perf framework unthrottled the event in the timer interrupt handler, it triggers riscv_pmu_start() function and causes a WARN_ON_ONCE() warning, as shown below: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 240 at drivers/perf/riscv_pmu.c:184 riscv_pmu_start+0x7c/0x8e Modules linked in: CPU: 0 PID: 240 Comm: ls Not tainted 6.4-rc4-g19d0788e9ef2 #1 Hardware name: SiFive (DT) epc : riscv_pmu_start+0x7c/0x8e ra : riscv_pmu_start+0x28/0x8e epc : ffffffff80aef864 ra : ffffffff80aef810 sp : ffff8f80004db6f0 gp : ffffffff81c83750 tp : ffffaf80069f9bc0 t0 : ffff8f80004db6c0 t1 : 0000000000000000 t2 : 000000000000001f s0 : ffff8f80004db720 s1 : ffffaf8008ca1068 a0 : 0000ffffffffffff a1 : 0000000000000000 a2 : 0000000000000001 a3 : 0000000000000870 a4 : 0000000000000000 a5 : 0000000000000000 a6 : 0000000000000840 a7 : 0000000000000030 s2 : 0000000000000000 s3 : ffffaf8005165800 s4 : ffffaf800424da00 s5 : ffffffffffffffff s6 : ffffffff81cc7590 s7 : 0000000000000000 s8 : 0000000000000006 s9 : 0000000000000001 s10: ffffaf807efbc340 s11: ffffaf807efbbf00 t3 : ffffaf8006a16028 t4 : 00000000dbfbb796 t5 : 0000000700000000 t6 : ffffaf8005269870 status: 0000000200000100 badaddr: 0000000000000000 cause: 0000000000000003 [<ffffffff80aef864>] riscv_pmu_start+0x7c/0x8e [<ffffffff80185b56>] perf_adjust_freq_unthr_context+0x15e/0x174 [<ffffffff80188642>] perf_event_task_tick+0x88/0x9c [<ffffffff800626a8>] scheduler_tick+0xfe/0x27c [<ffffffff800b5640>] update_process_times+0x9a/0xba [<ffffffff800c5bd4>] tick_sched_handle+0x32/0x66 [<ffffffff800c5e0c>] tick_sched_timer+0x64/0xb0 [<ffffffff800b5e50>] __hrtimer_run_queues+0x156/0x2f4 [<ffffffff800b6bdc>] hrtimer_interrupt+0xe2/0x1fe [<ffffffff80acc9e8>] riscv_timer_interrupt+0x38/0x42 [<ffffffff80090a16>] handle_percpu_devid_irq+0x90/0x1d2 [<ffffffff8008a9f4>] generic_handle_domain_irq+0x28/0x36 After referring other PMU drivers like Arm, Loongarch, Csky, and Mips, they don't call *_pmu_stop() to update with PERF_HES_STOPPED flag after perf_event_overflow() function nor do they add PERF_HES_STOPPED flag checking in *_pmu_start() which don't cause this warning.

2023-07-12regmap-irq: Fix out-of-bounds access when allocating config buffersIsaac J. Manjarres
When allocating the 2D array for handling IRQ type registers in regmap_add_irq_chip_fwnode(), the intent is to allocate a matrix with num_config_bases rows and num_config_regs columns. This is currently handled by allocating a buffer to hold a pointer for each row (i.e. num_config_bases). After that, the logic attempts to allocate the memory required to hold the register configuration for each row. However, instead of doing this allocation for each row (i.e. num_config_bases allocations), the logic erroneously does this allocation num_config_regs number of times. This scenario can lead to out-of-bounds accesses when num_config_regs is greater than num_config_bases. Fix this by updating the terminating condition of the loop that allocates the memory for holding the register configuration to allocate memory only for each row in the matrix. Amit Pundir reported a crash that was occurring on his db845c device due to memory corruption (see "Closes" tag for Amit's report). The KASAN report below helped narrow it down to this issue: [ 14.033877][ T1] ================================================================== [ 14.042507][ T1] BUG: KASAN: invalid-access in regmap_add_irq_chip_fwnode+0x594/0x1364 [ 14.050796][ T1] Write of size 8 at addr 06ffff8081021850 by task init/1 [ 14.242004][ T1] The buggy address belongs to the object at ffffff8081021850 [ 14.242004][ T1] which belongs to the cache kmalloc-8 of size 8 [ 14.255669][ T1] The buggy address is located 0 bytes inside of [ 14.255669][ T1] 8-byte region [ffffff8081021850, ffffff8081021858) Fixes: faa87ce9196d ("regmap-irq: Introduce config registers for irq types") Reported-by: Amit Pundir <amit.pundir@linaro.org> Closes: https://lore.kernel.org/all/CAMi1Hd04mu6JojT3y6wyN2YeVkPR5R3qnkKJ8iR8if_YByCn4w@mail.gmail.com/ Tested-by: John Stultz <jstultz@google.com> Tested-by: Amit Pundir <amit.pundir@linaro.org> # tested on Dragonboard 845c Cc: stable@vger.kernel.org # v6.0+ Cc: Aidan MacDonald <aidanmacdonald.0x0@gmail.com> Cc: Saravana Kannan <saravanak@google.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: "Isaac J.

Especially #4 and #6 address the same observation, but both need to be applied to avoid TX hang occurrences in the scenario described in the patches. ==================== Signed-off-by: Florian Kauer <florian.kauer@linutronix.de> Reviewed-by: Kurt Kanzenbach <kurt@linutronix.de> Acked-by: Vinicius Costa Gomes <vinicius.gomes@intel.com> Reviewed-by: Muhammad Husaini Zulkifli <muhammad.husaini.zulkifli@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> Signed-off-by: David S.

2023-07-11wifi: iwlwifi: remove 'use_tfh' config to fix crashJohannes Berg
This is equivalent to 'gen2', and it was always confusing to have two identical config entries. The split config patch actually had been originally developed after removing 'use_tfh" and didn't add the use_tfh in the new configs as they'd later been copied to the new files. Thus the easiest way to fix the init crash here now is to just remove use_tfh (which is erroneously unset in most of the configs now) and use 'gen2' in the code instead. There's possibly still an unwind error in iwl_txq_gen2_init() as it crashes if TXQ 0 fails to initialize, but we can deal with it later since the original failure is due to the use_tfh confusion.

Commit 8d36694245f2 ("PM: QoS: Add check to make sure CPU freq is non-negative") makes sure CPU freq is non-negative to avoid negative value converting to unsigned data type. However, when the value is PM_QOS_DEFAULT_VALUE, pm_qos_update_target specifically uses c->default_value which is set to FREQ_QOS_MIN/MAX_DEFAULT_VALUE when cpufreq_policy_alloc is executed, for this case handling. Adding check for PM_QOS_DEFAULT_VALUE to let default setting work will fix this problem.

In response to a disk I/O request, Hyper-V has been observed to return SRB status value 0x30. This indicates the request was not processed by Hyper-V because low memory conditions on the host caused an internal error. The 0x30 status is not recognized by storvsc, so the I/O operation is not flagged as an error. The request is treated as if it completed normally but with zero data transferred, causing a flood of retries.

2023-07-11drm/client: Send hotplug event after registering a clientThomas Zimmermann
Generate a hotplug event after registering a client to allow the client to configure its display. Remove the hotplug calls from the existing clients for fbdev emulation. This change fixes a concurrency bug between registering a client and receiving events from the DRM core. The bug is present in the fbdev emulation of all drivers. The fbdev emulation currently generates a hotplug event before registering the client to the device. For each new output, the DRM core sends an additional hotplug event to each registered client. If the DRM core detects first output between sending the artificial hotplug and registering the device, the output's hotplug event gets lost. If this is the first output, the fbdev console display remains dark. This has been observed with amdgpu and fbdev-generic. Fix this by adding hotplug generation directly to the client's register helper drm_client_register(). Registering the client and receiving events are serialized by struct drm_device.clientlist_mutex. So an output is either configured by the initial hotplug event, or the client has already been registered. The bug was originally added in commit 6e3f17ee73f7 ("drm/fb-helper: generic: Call drm_client_add() after setup is done"), in which adding a client and receiving a hotplug event switched order. It was hidden, as most hardware and drivers have at least on static output configured. Other drivers didn't use the internal DRM client or still had struct drm_mode_config_funcs.output_poll_changed set. That callback handled hotplug events as well. After not setting the callback in amdgpu in commit 0e3172bac3f4 ("drm/amdgpu: Don't set struct drm_driver.output_poll_changed"), amdgpu did not show a framebuffer console if output events got lost. The bug got copy-pasted from fbdev-generic into the other fbdev emulation.
