π gfx_v7_0_get_rb_active_bitmap β Kernel API Manual
okay so bestie, welcome to the gfx_v7_0_get_rb_active_bitmap(9) page π this one lives in the Kernel API Manual and it's short, sweet, and does exactly one thing. no cap.
β¨ NAME β¨
gfx_v7_0_get_rb_active_bitmap β computes the mask of enabled RBs π§
πΈ SYNOPSIS πΈ
u32 gfx_v7_0_get_rb_active_bitmap (struct amdgpu_device *adev );
π ARGUMENTS π
adevβ anamdgpu_devicepointer π«Ά that's it, that's the whole argument list, we love a low-maintenance queen
π₯ DESCRIPTION π₯
so what does she do? she calculates the bitmask of enabled RBs (CIK) π and then β plot twist β returns the enabled RB bitmask. literally that's the whole arc. get the bitmap, give the bitmap. main character energy, zero drama β¨

lowkey all of these are the same era of AMDGPU code, so if you're deep in gfx_v7_0 you're gonna be seeing these names a lot π iykyk
