Hello all,
Are the drivers in drivers/misc/hdpuftrs dead?
I can't locate anywhere to enable CONFIG_HDPU_FEATURES. Also, both
hdpu_cpustate.c and hdpu_nexus.c register as platform drivers but I
can't find any users in the mainline tree.
Both drivers seem kind of... ugly...
hdpu_cpustate.c does a lock_kernel() in the open file_operation. Then
does a spin_lock() when checking if the open is O_EXCL.
I'm no expert on locking but the lock_kernel() seems unnecessary.
Regards,
Hartley
