Subject: [PATCH 7/9] librtas: Use /dev/papr-indices when available for
|
|
set-dynamic-indicator
|
|
|
|
Changes for rtas_set_dynamic_indicator() to use new kernel
|
|
interface provided by /dev/papr-indices entry. The kernel provides
|
|
PAPR_DYNAMIC_INDICATOR_IOC_SET ioctl for /dev/papr-indices to
|
|
execute ibm,set-dynamic-indicator RTAS Call.
|
|
|
|
If /dev/papr-indices entry is available, the new kernel interface
|
|
is used with the following programming model:
|
|
|
|
fd = open("/dev/papr-indices", O_RDWR);
|
|
copy location-code to
|
|
papr_indices_io_block.dynamic_param.location_code_str
|
|
papr_indices_io_block.dynamic_param.token = token-val;
|
|
papr_indices_io_block.dynamic_param.state = new-state;
|
|
ret = ioctl(fd, PAPR_DYNAMIC_INDICATOR_IOC_SET,
|
|
papr_indices_io_block);
