Enumeration Type Documentation

aiclk_arb_max

enum aiclk_arb_max

AICLK maximum frequency arbiters.

These arbiters set upper limits on the AICLK frequency. The effective maximum frequency is determined by the lowest enabled arbiter value.

Warning

The order of these enum values must be preserved for compatibility.

Enumerator
aiclk_arb_max_fmax	Maximum frequency limit
aiclk_arb_max_tdp	Thermal Design Power limit
aiclk_arb_max_fast_tdc	Fast Thermal Design Current limit
aiclk_arb_max_tdc	Thermal Design Current limit
aiclk_arb_max_thm	Thermal limit
aiclk_arb_max_board_power	Board power limit
aiclk_arb_max_voltage	Voltage limit
aiclk_arb_max_gddr_thm	GDDR thermal limit
aiclk_arb_max_doppler_slow	Doppler slow throttling limit
aiclk_arb_max_doppler_critical	Doppler critical throttling limit
aiclk_arb_max_host_fmax	Host-adjustable fmax ceiling
aiclk_arb_max_count	Number of max arbiters

aiclk_arb_min

enum aiclk_arb_min

AICLK minimum frequency arbiters.

These arbiters set lower limits on the AICLK frequency. The effective minimum frequency is determined by the highest enabled arbiter value.

Warning

The order of these enum values must be preserved for compatibility.

Enumerator
aiclk_arb_min_fmin	Minimum frequency limit
aiclk_arb_min_busy	Busy state frequency requirement
aiclk_arb_min_count	Number of min arbiters

targ_freq_reason

enum targ_freq_reason

Enumerator
limit_reason_min_arb	We are being limited by a min arbiter
limit_reason_max_arb	We are being limited by a max arbiter
limit_reason_fmin	The aiclk was arbitrated below fmin, and therefore was set to fmin
limit_reason_sweep	The aiclk is random due to sweep being enabled
limit_reason_forced	The aiclk is forced
