boolean_regs_ptr

__u64 drm_i915_perf_oa_config::boolean_regs_ptr

@boolean_regs_ptr:

Pointer to tuples of u32 values (register address, value) for mux registers. Expected length of buffer is (2 * sizeof(u32) * &n_boolean_regs).

flex_regs_ptr

__u64 drm_i915_perf_oa_config::flex_regs_ptr

@flex_regs_ptr:

Pointer to tuples of u32 values (register address, value) for mux registers. Expected length of buffer is (2 * sizeof(u32) * &n_flex_regs).

mux_regs_ptr

__u64 drm_i915_perf_oa_config::mux_regs_ptr

@mux_regs_ptr:

Pointer to tuples of u32 values (register address, value) for mux registers. Expected length of buffer is (2 * sizeof(u32) * &n_mux_regs).

n_boolean_regs

__u32 drm_i915_perf_oa_config::n_boolean_regs

@n_boolean_regs:

Number of boolean regs in &boolean_regs_ptr.

n_flex_regs

__u32 drm_i915_perf_oa_config::n_flex_regs

@n_flex_regs:

Number of flex regs in &flex_regs_ptr.

n_mux_regs

__u32 drm_i915_perf_oa_config::n_mux_regs

@n_mux_regs:
