2021-02-02amba: Make the remove callback return voidUwe Kleine-König
All amba drivers return 0 in their remove callback. Together with the driver core ignoring the return value anyhow, it doesn't make sense to return a value here. Change the remove prototype to return void, which makes it explicit that returning an error value doesn't work as expected. This simplifies changing the core remove callback to return void, too.

2021-02-02ALSA: jack: implement software jack injection via debugfsHui Wang
This change adds audio jack injection feature through debugfs, with this feature, we could validate alsa userspace changes by injecting plugin or plugout events to the non-phantom audio jacks. With this change, the sound core will build the folders $debugfs_mount_dir/sound/cardN if SND_DEBUG and DEBUG_FS are enabled. And if users also enable the SND_JACK_INJECTION_DEBUG, the jack injection nodes will be built in the folder cardN like below: $tree $debugfs_mount_dir/sound $debugfs_mount_dir/sound ├── card0 │   ├── HDMI_DP_pcm_10_Jack │   │   ├── jackin_inject │   │   ├── kctl_id │   │   ├── mask_bits │   │   ├── status │   │   ├── sw_inject_enable │   │   └── type ... │   └── HDMI_DP_pcm_9_Jack │   ├── jackin_inject │   ├── kctl_id │   ├── mask_bits │   ├── status │   ├── sw_inject_enable │   └── type └── card1 ├── HDMI_DP_pcm_5_Jack │   ├── jackin_inject │   ├── kctl_id │   ├── mask_bits │   ├── status │   ├── sw_inject_enable │   └── type ... ├── Headphone_Jack │   ├── jackin_inject │   ├── kctl_id │   ├── mask_bits │   ├── status │   ├── sw_inject_enable │   └── type └── Headset_Mic_Jack ├── jackin_inject ├── kctl_id ├── mask_bits ├── status ├── sw_inject_enable └── type The nodes kctl_id, mask_bits, status and type are read-only, users could check jack or jack_kctl's information through them. The nodes sw_inject_enable and jackin_inject are directly used for injection. The sw_inject_enable is read-write, users could check if software injection is enabled or not on this jack, and users could echo 1 or 0 to enable or disable software injection on this jack. Once the injection is enabled, the jack will not change by hardware events anymore, once the injection is disabled, the jack will restore the last reported hardware events to the jack. The jackin_inject is write-only, if the injection is enabled, users could echo 1 or 0 to this node to inject plugin or plugout events to this jack. For the detailed usage information on these nodes, please refer to Documentation/sound/designs/jack-injection.rst.

Call of invalid helper sporadically leads to corruption of vt_tree/cf_tree of hfsc_class that causes kernel oops: Oops: 0000 [#1] SMP PTI CPU: 1 PID: 0 Comm: swapper/1 Not tainted 5.11.0-8f6859df #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.10.2-0-g5f4c7b1-prebuilt.qemu-project.org 04/01/2014 RIP: 0010:rb_insert_color+0x18/0x190 Code: c3 31 c0 c3 0f 1f 40 00 66 2e 0f 1f 84 00 00 00 00 00 48 8b 07 48 85 c0 0f 84 05 01 00 00 48 8b 10 f6 c2 01 0f 85 34 01 00 00 <48> 8b 4a 08 49 89 d0 48 39 c1 74 7d 48 85 c9 74 32 f6 01 01 75 2d RSP: 0018:ffffc900000b8bb0 EFLAGS: 00010246 RAX: ffff8881ef4c38b0 RBX: ffff8881d956e400 RCX: ffff8881ef4c38b0 RDX: 0000000000000000 RSI: ffff8881d956f0a8 RDI: ffff8881d956e4b0 RBP: 0000000000000000 R08: 000000d5c4e249da R09: 1600000000000000 R10: ffffc900000b8be0 R11: ffffc900000b8b28 R12: 0000000000000001 R13: 000000000000005a R14: ffff8881f0905000 R15: ffff8881f0387d00 FS: 0000000000000000(0000) GS:ffff8881f8b00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000008 CR3: 00000001f4796004 CR4: 0000000000060ee0 Call Trace: <IRQ> init_vf.isra.19+0xec/0x250 [sch_hfsc] hfsc_enqueue+0x245/0x300 [sch_hfsc] ? fib_rules_lookup+0x12a/0x1d0 ? __dev_queue_xmit+0x4b6/0x930 ? hfsc_delete_class+0x250/0x250 [sch_hfsc] __dev_queue_xmit+0x4b6/0x930 ? ip6_finish_output2+0x24d/0x590 ip6_finish_output2+0x24d/0x590 ? ip6_output+0x6c/0x130 ip6_output+0x6c/0x130 ? __ip6_finish_output+0x110/0x110 mld_sendpack+0x224/0x230 mld_ifc_timer_expire+0x186/0x2c0 ? igmp6_group_dropped+0x200/0x200 call_timer_fn+0x2d/0x150 run_timer_softirq+0x20c/0x480 ? tick_sched_do_timer+0x60/0x60 ? tick_sched_timer+0x37/0x70 __do_softirq+0xf7/0x2cb irq_exit+0xa0/0xb0 smp_apic_timer_interrupt+0x74/0x150 apic_timer_interrupt+0xf/0x20 </IRQ> Fixes: e5f0e8f8e456 ("net: sched: introduce and use qdisc tree flush/purge helpers") Signed-off-by: Alexander Ovechkin <ovov@yandex-team.ru> Reported-by: Alexander Kuznetsov <wwfq@yandex-team.ru> Acked-by: Dmitry Monakhov <dmtrmonakhov@yandex-team.ru> Acked-by: Dmitry Yakunin <zeil@yandex-team.ru> Acked-by: Cong Wang <xiyou.wangcong@gmail.com> Link: https://lore.kernel.org/r/20210201200049.299153-1-ovov@yandex-team.ru Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2021-02-02i3c: Make remove callback return voidUwe Kleine-König
The driver core ignores the return value of struct bus_type::remove() because there is only little that can be done. To simplify the quest to make this function return void, let struct i3c_driver::remove() return void, too. This makes it obvious that returning an error code is a bad idea and future driver authors cannot get that wrong. Up to now there are no drivers with a remove callback, so there is no need to adapt drivers.

2021-02-01cfg80211: fix netdev registration deadlockJohannes Berg
If register_netdevice() fails after having called cfg80211's netdev notifier (cfg80211_netdev_notifier_call) it will call the notifier again with UNREGISTER. This would then lock the wiphy mutex because we're marked as registered, which causes a deadlock. Fix this by separately keeping track of whether or not we're in the middle of registering to also skip the notifier call on this unregister.

2021-02-01perf/x86/intel: Add perf core PMU support for Sapphire RapidsKan Liang
Add perf core PMU support for the Intel Sapphire Rapids server, which is the successor of the Intel Ice Lake server. The enabling code is based on Ice Lake, but there are several new features introduced. The event encoding is changed and simplified, e.g., the event codes which are below 0x90 are restricted to counters 0-3. The event codes which above 0x90 are likely to have no restrictions. The event constraints, extra_regs(), and hardware cache events table are changed accordingly. A new Precise Distribution (PDist) facility is introduced, which further minimizes the skid when a precise event is programmed on the GP counter 0. Enable the Precise Distribution (PDist) facility with :ppp event. For this facility to work, the period must be initialized with a value larger than 127. Add spr_limit_period() to apply the limit for :ppp event. Two new data source fields, data block & address block, are added in the PEBS Memory Info Record for the load latency event. To enable the feature, - An auxiliary event has to be enabled together with the load latency event on Sapphire Rapids. A new flag PMU_FL_MEM_LOADS_AUX is introduced to indicate the case. A new event, mem-loads-aux, is exposed to sysfs for the user tool. Add a check in hw_config(). If the auxiliary event is not detected, return an unique error -ENODATA. - The union perf_mem_data_src is extended to support the new fields. - Ice Lake and earlier models do not support block information, but the fields may be set by HW on some machines. Add pebs_no_block to explicitly indicate the previous platforms which don't support the new block fields. Accessing the new block fields are ignored on those platforms. A new store Latency facility is introduced, which leverages the PEBS facility where it can provide additional information about sampled stores. The additional information includes the data address, memory auxiliary info (e.g. Data Source, STLB miss) and the latency of the store access. To enable the facility, the new event (0x02cd) has to be programed on the GP counter 0. A new flag PERF_X86_EVENT_PEBS_STLAT is introduced to indicate the event. The store_latency_data() is introduced to parse the memory auxiliary info. The layout of access latency field of PEBS Memory Info Record has been changed. Two latency, instruction latency (bit 15:0) and cache access latency (bit 47:32) are recorded. - The cache access latency is similar to previous memory access latency. For loads, the latency starts by the actual cache access until the data is returned by the memory subsystem. For stores, the latency starts when the demand write accesses the L1 data cache and lasts until the cacheline write is completed in the memory subsystem. The cache access latency is stored in low 32bits of the sample type PERF_SAMPLE_WEIGHT_STRUCT. - The instruction latency starts by the dispatch of the load operation for execution and lasts until completion of the instruction it belongs to. Add a new flag PMU_FL_INSTR_LATENCY to indicate the instruction latency support. The instruction latency is stored in the bit 47:32 of the sample type PERF_SAMPLE_WEIGHT_STRUCT. Extends the PERF_METRICS MSR to feature TMA method level 2 metrics. The lower half of the register is the TMA level 1 metrics (legacy). The upper half is also divided into four 8-bit fields for the new level 2 metrics. Expose all eight Topdown metrics events to user space.
