2021-06-01ASoC: SOF: reset enabled_cores state at suspendKai Vehmanen1-0/+1
The recent changes to use common code to power up/down DSP cores also removed the reset of the core state at suspend. It turns out this is still needed. When the firmware state is reset to SOF_FW_BOOT_NOT_STARTED, also enabled_cores should be reset, and existing DSP drivers depend on this.

2021-05-31x86/thermal: Fix LVT thermal setup for SMI delivery modeBorislav Petkov3-5/+23
There are machines out there with added value crap^WBIOS which provide an SMI handler for the local APIC thermal sensor interrupt. Out of reset, the BSP on those machines has something like 0x200 in that APIC register (timestamps left in because this whole issue is timing sensitive): [ 0.033858] read lvtthmr: 0x330, val: 0x200 which means: - bit 16 - the interrupt mask bit is clear and thus that interrupt is enabled - bits [10:8] have 010b which means SMI delivery mode. Now, later during boot, when the kernel programs the local APIC, it soft-disables it temporarily through the spurious vector register: setup_local_APIC: ... /* * If this comes from kexec/kcrash the APIC might be enabled in * SPIV. Soft disable it before doing further initialization. */ value = apic_read(APIC_SPIV); value &= ~APIC_SPIV_APIC_ENABLED; apic_write(APIC_SPIV, value); which means (from the SDM): "10.4.7.2 Local APIC State After It Has Been Software Disabled ... * The mask bits for all the LVT entries are set. Attempts to reset these bits will be ignored." And this happens too: [ 0.124111] APIC: Switch to symmetric I/O mode setup [ 0.124117] lvtthmr 0x200 before write 0xf to APIC 0xf0 [ 0.124118] lvtthmr 0x10200 after write 0xf to APIC 0xf0 This results in CPU 0 soft lockups depending on the placement in time when the APIC soft-disable happens. Those soft lockups are not 100% reproducible and the reason for that can only be speculated as no one tells you what SMM does. Likely, it confuses the SMM code that the APIC is disabled and the thermal interrupt doesn't doesn't fire at all, leading to CPU 0 stuck in SMM forever... Now, before 4f432e8bb15b ("x86/mce: Get rid of mcheck_intel_therm_init()") due to how the APIC_LVTTHMR was read before APIC initialization in mcheck_intel_therm_init(), it would read the value with the mask bit 16 clear and then intel_init_thermal() would replicate it onto the APs and all would be peachy - the thermal interrupt would remain enabled. But that commit moved that reading to a later moment in intel_init_thermal(), resulting in reading APIC_LVTTHMR on the BSP too late and with its interrupt mask bit set. Thus, revert back to the old behavior of reading the thermal LVT register before the APIC gets initialized.

2021-05-31ALSA: hda: Fix a regression in Capture Switch mixer readTakashi Iwai1-0/+1
The recent commit to drop the HDA-specific mute-LED control, e65bf99718b5 ("ALSA: HDA - remove the custom implementation for the audio LED trigger"), caused a regression on the mixer element read for "Capture Switch" when it's built from bind controls. The function create_bind_cap_vol_ctl() creates the snd_kcontrol_new object directly via snd_hda_gen_add_kctl() instead of add_control(). Although the commit above added a workaround for the SNDRV_CTL_ACCESS_READWRITE in add_control() as default, this code path fell out from the radar. As a result, now the driver gives -EPERM error because of the lack of the proper access bit at reading "Capture Switch" element value. Fix the regression by setting the access bit properly.

2021-05-31perf/x86/intel/uncore: Fix a kernel WARNING triggered by maxcpus=1Kan Liang1-2/+4
A kernel WARNING may be triggered when setting maxcpus=1. The uncore counters are Die-scope. When probing a PCI device, only the BUS information can be retrieved. The uncore driver has to maintain a mapping table used to calculate the logical Die ID from a given BUS#. Before the patch ba9506be4e40, the mapping table stores the mapping information from the BUS# -> a Physical Socket ID. To calculate the logical die ID, perf does, - In snbep_pci2phy_map_init(), retrieve the BUS# -> a Physical Socket ID from the UBOX PCI configure space. - Calculate the mapping information (a BUS# -> a Physical Socket ID) for the other PCI BUS. - In the uncore_pci_probe(), get the physical Socket ID from a given BUS and the mapping table. - Calculate the logical Die ID Since only the logical Die ID is required, with the patch ba9506be4e40, the mapping table stores the mapping information from the BUS# -> a logical Die ID. Now perf does, - In snbep_pci2phy_map_init(), retrieve the BUS# -> a Physical Socket ID from the UBOX PCI configure space. - Calculate the logical Die ID - Calculate the mapping information (a BUS# -> a logical Die ID) for the other PCI BUS. - In the uncore_pci_probe(), get the logical die ID from a given BUS and the mapping table. When calculating the logical Die ID, -1 may be returned, especially when maxcpus=1. Here, -1 means the logical Die ID is not found. But when calculating the mapping information for the other PCI BUS, -1 indicates that it's the other PCI BUS that requires the calculation of the mapping. The driver will mistakenly do the calculation. Uses the -ENODEV to indicate the case which the logical Die ID is not found. The driver will not mess up the mapping table anymore.

2021-05-31nvme-rdma: fix in-casule data send for chained sglsSagi Grimberg1-2/+3
We have only 2 inline sg entries and we allow 4 sg entries for the send wr sge. Larger sgls entries will be chained. However when we build in-capsule send wr sge, we iterate without taking into account that the sgl may be chained and still fit in-capsule (which can happen if the sgl is bigger than 2, but lower-equal to 4). Fix in-capsule data mapping to correctly iterate chained sgls.

Fixed link does not need mdio bus and in that case mdio_bus_data will not be allocated. Before using mdio_bus_data we should check for NULL. This patch fix the kernel panic due to NULL pointer dereference of mdio_bus_data when it is not allocated. Without this patch we do see following kernel crash caused due to kernel NULL pointer dereference.

This refactors the user notification code to have a do / while loop around the completion condition. This has a small change in semantic, in that previously we ignored addfd calls upon wakeup if the notification had been responded to, but instead with the new change we check for an outstanding addfd calls prior to returning to userspace. Rodrigo Campos also identified a bug that can result in addfd causing an early return, when the supervisor didn't actually handle the syscall [1].
