[PATCH 1/1] EDAC/igen6: Fix conversion of system address to physical memory address

by Qiuxu Zhuo

The conversion of system address to physical memory address (as viewed by the memory controller) by igen6_edac is incorrect when the system address is above the TOM (Total amount Of populated physical Memory) for Elkhart Lake and Ice Lake (Neural Network Processor). Fix this conversion.

[PATCH v5.15] powerpc: Avoid nmi_enter/nmi_exit in real mode interrupt.

by Jinjie Ruan

From: Mahesh Salgaonkar <mahesh(a)linux.ibm.com> nmi_enter()/nmi_exit() touches per cpu variables which can lead to kernel crash when invoked during real mode interrupt handling (e.g. early HMI/MCE interrupt handler) if percpu allocation comes from vmalloc area. Early HMI/MCE handlers are called through DEFINE_INTERRUPT_HANDLER_NMI() wrapper which invokes nmi_enter/nmi_exit calls. We don't see any issue when percpu allocation is from the embedded first chunk. However with CONFIG_NEED_PER_CPU_PAGE_FIRST_CHUNK enabled there are chances where percpu allocation can come from the vmalloc area. With kernel command line "percpu_alloc=page" we can force percpu allocation to come from vmalloc area and can see kernel crash in machine_check_early: [ 1.215714] NIP [c000000000e49eb4] rcu_nmi_enter+0x24/0x110 [ 1.215717] LR [c0000000000461a0] machine_check_early+0xf0/0x2c0 [ 1.215719] --- interrupt: 200 [ 1.215720] [c000000fffd73180] [0000000000000000] 0x0 (unreliable) [ 1.215722] [c000000fffd731b0] [0000000000000000] 0x0 [ 1.215724] [c000000fffd73210] [c000000000008364] machine_check_early_common+0x134/0x1f8 Fix this by avoiding use of nmi_enter()/nmi_exit() in real mode if percpu first chunk is not embedded.

[PATCH] drm/amd/display: avoid using null object of framebuffer

Instead of using state->fb->obj[0] directly, get object from framebuffer by calling drm_gem_fb_get_obj() and return error code when object is null to avoid using null object of framebuffer.

[PATCH v3] scsi: sd: retry command SYNC CACHE if format in progress

by Yihang Li

If formatting a suspended disk (such as formatting with different DIF type), the disk will be resuming first, and then the format command will submit to the disk through SG_IO ioctl. When the disk is processing the format command, the system does not submit other commands to the disk. Therefore, the system attempts to suspend the disk again and sends the SYNC CACHE command. However, the SYNC CACHE command will fail because the disk is in the formatting process, which will cause the runtime_status of the disk to error and it is difficult for user to recover it. Error info like: [ 669.925325] sd 6:0:6:0: [sdg] Synchronizing SCSI cache [ 670.202371] sd 6:0:6:0: [sdg] Synchronize Cache(10) failed: Result: hostbyte=0x00 driverbyte=DRIVER_OK [ 670.216300] sd 6:0:6:0: [sdg] Sense Key : 0x2 [current] [ 670.221860] sd 6:0:6:0: [sdg] ASC=0x4 ASCQ=0x4 To solve the issue, retry the command until format command is finished.

[PATCH V2] pmdomain: imx: wait SSAR when i.MX93 power domain on

by Peng Fan (OSS)

From: Peng Fan <peng.fan(a)nxp.com> With "quiet" set in bootargs, there is power domain failure: "imx93_power_domain 44462400.power-domain: pd_off timeout: name: 44462400.power-domain, stat: 4" The current power on opertation takes ISO state as power on finished flag, but it is wrong. Before powering on operation really finishes, powering off comes and powering off will never finish because the last powering on still not finishes, so the following powering off actually not trigger hardware state machine to run. SSAR is the last step when powering on a domain, so need to wait SSAR done when powering on. Since EdgeLock Enclave(ELE) handshake is involved in the flow, enlarge the waiting time to 10ms for both on and off to avoid timeout.

Re: [PATCH 6.6.y 00/12] Backport "make svc_stat per-net instead of global"

Now I'll see the patchset "Make nfsd stats visible in network ns" [1]. kernelnewbies [2] starts with d98416cc2154 ("nfsd: rename NFSD_NET_* to NFSD_STATS_*"), the others are probably some preparation commits.

[PATCH] soc: imx: imx8m-blk-ctrl: Fix NULL pointer dereference

by Ma Ke

Check bc->bus_power_dev = dev_pm_domain_attach_by_name() return value using IS_ERR_OR_NULL() instead of plain IS_ERR(), and fail if bc->bus_power_dev is either error or NULL. In case a power domain attached by dev_pm_domain_attach_by_name() is not described in DT, dev_pm_domain_attach_by_name() returns NULL, which is then used, which leads to NULL pointer dereference. Found by code review.
