This issue doesn't happen on Windows. Comparing the GPIO register configuration between Windows and Linux bit 20 has been configured as a pull up on Windows, but not on Linux. Checking GPIO declaration from the firmware it is clear it *should* have been a pull up on Linux as well. ``` GpioInt (Level, ActiveLow, Exclusive, PullUp, 0x0000, "\\_SB.GPIO", 0x00, ResourceConsumer, ,) { // Pin list 0x0007 } ``` On Linux amd_gpio_set_config() is currently only used for programming the debounce. Actually the GPIO core calls it with all the arguments that are supported by a GPIO, pinctrl-amd just responds `-ENOTSUPP`. To solve this issue expand amd_gpio_set_config() to support the other arguments amd_pinconf_set() supports, namely `PIN_CONFIG_BIAS_PULL_DOWN`, `PIN_CONFIG_BIAS_PULL_UP`, and `PIN_CONFIG_DRIVE_STRENGTH`.

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).

While these checks are appropriate to verify that well tested hardware devices have an adequate zone configurations, they lack in certain areas which may result in issues with potentially buggy emulated devices implemented with user drivers such as ublk or tcmu. Specifically, this function does not check if the device driver indicated support for the mandatory zone append writes, that is, if the device max_zone_append_sectors queue limit is set to a non-zero value. Additionally, invalid zones such as a zero length zone with a start sector equal to the device capacity will not be detected and result in out of bounds use of the zone bitmaps prepared with the callback function blk_revalidate_zone_cb(). This series address these issues by modifying the 4 block device drivers that currently support zoned block devices to ensure that they all set a zoned device zone size and max zone append sectors limit before executing blk_revalidate_disk_zones(). With these changes in place, patch 5 improves blk_revalidate_disk_zones() to address the missing checks, relying on the fact that the zone size and zone append limit are normally set when this function is called.

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. Thus, it's recommended to remove this unnecessary check in riscv_pmu_start() function to prevent this warning.
