Primarily adding # this capability for debug. But when doing so, the code did not # consider the case of cpu-less nodes. So when reading the _cmd_ or # _mode_ file of a cpu-less node will create this crash. # # Faulting instruction address: 0xc0000000000d0d58 # Oops: Kernel access of bad area, sig: 11 [#1] # ... # CPU: 67 PID: 5301 Comm: cat Not tainted 5.2.0-rc6-next-20190627+ #19 # NIP: c0000000000d0d58 LR: c00000000049aa18 CTR:c0000000000d0d50 # REGS: c00020194548f9e0 TRAP: 0300 Not tainted (5.2.0-rc6-next-20190627+) # MSR: 9000000000009033 <SF,HV,EE,ME,IR,DR,RI,LE> CR:28022822 XER: 00000000 # CFAR: c00000000049aa14 DAR: 000000000003fc08 DSISR:40000000 IRQMASK: 0 # ... # NIP imc_mem_get+0x8/0x20 # LR simple_attr_read+0x118/0x170 # Call Trace: # simple_attr_read+0x70/0x170 (unreliable) # debugfs_attr_read+0x6c/0xb0 # __vfs_read+0x3c/0x70 # vfs_read+0xbc/0x1a0 # ksys_read+0x7c/0x140 # system_call+0x5c/0x70 # # Patch fixes the issue with a more robust check for vbase to NULL. # # Before patch, ls output for the debugfs imc directory # # # ls /sys/kernel/debug/powerpc/imc/ # imc_cmd_0 imc_cmd_251 imc_cmd_253 imc_cmd_255 imc_mode_0 imc_mode_251 imc_mode_253 imc_mode_255 # imc_cmd_250 imc_cmd_252 imc_cmd_254 imc_cmd_8 imc_mode_250 imc_mode_252 imc_mode_254 imc_mode_8 # # After patch, ls output for the debugfs imc directory # # # ls /sys/kernel/debug/powerpc/imc/ # imc_cmd_0 imc_cmd_8 imc_mode_0 imc_mode_8 # # Actual bug here is that, we have two loops with potentially different # loop counts.

Patch fixes the loop count in # latter based on the struct mem_info.
