Add sysfs entries for the min, max, and defaults for each of
engine scheduler controls for every hardware engine class.
Non-elevated user IOCTLs to set these controls must be within
the min-max ranges of the sysfs entries, elevated user can set
these controls to any value. However, introduced compile time
CONFIG min-max values which restricts elevated user to be in
compile time min-max range if at all sysfs min/max are violated.
Sysfs entries examples are,
DUT# cat /sys/class/drm/cardX/device/tileN/gtN/engines/ccs/.defaults/
job_timeout_max job_timeout_ms preempt_timeout_min timeslice_duration_max timeslice_duration_us
job_timeout_min preempt_timeout_max preempt_timeout_us timeslice_duration_min
DUT# cat /sys/class/drm/card1/device/tileN/gtN/engines/ccs/
.defaults/ job_timeout_min preempt_timeout_max preempt_timeout_us timeslice_duration_min
job_timeout_max job_timeout_ms preempt_timeout_min timeslice_duration_max timeslice_duration_us
V12:
- Rebase
V11:
- Make engine_get_prop_minmax and enforce_sched_limit static - Matt
- use enum in place of string in engine_get_prop_minmax - Matt
- no need to use enforce_sched_limit or no need to filter min/max
per user type in sysfs - Matt
V10:
- Add kernel doc for non-static func
- Make helper to get min/max for range validation - Matt
- Filter min/max per user type
V9 :
- Rebase to use s/xe_engine/xe_hw_engine/ - Matt
V8 :
- fix enforce_sched_limit and avoid code duplication - Niranjana
- Make sure min < max - Niranjana
V7 :
- Rebase to replace hw engine with eclass interface
- return EINVAL in place of EPERM
- Use some APIs to avoid code duplication
V6 :
- Rebase changes to reflect per engine class props interface - MattB
- Use #if ENABLED - MattB
- Remove MAX_SCHED_TIMEOUT check as range validation is enough
V5 :
- Rebase to resolve conflicts - CI
V4 :
- Rebase
- Update commit to reflect tile addition
- Use XE_HW macro directly as they are already filtered
for CONFIG checks - Niranjana
- Add CONFIG for enable/disable min/max limitation
on elevated user. Default is enable - Matt/Joonas
V3 :
- Resolve CI hooks warning for kernel-doc
V2 :
- Restric min/max setting to #define default min/max for
elevated user - Himal
- Remove unrelated changes from patch - Niranjana
