• 70967ab9c   radeon: Use request_firmware() ... Browse Code »

  Loosely based on a patch by
  Jaswinder Singh Rajput .

  KMS support by Dave Airlie .

  For Radeon 100- to 500-series, firmware blobs look like:
  struct {
  __be32 datah;
  __be32 datal;
  } cp_ucode[256];

  For Radeon 600-series, there are two separate firmware blobs:
  __be32 me_ucode[PM4_UCODE_SIZE * 3];
  __be32 pfp_ucode[PFP_UCODE_SIZE];

  For Radeon 700-series, likewise:
  __be32 me_ucode[R700_PM4_UCODE_SIZE];
  __be32 pfp_ucode[R700_PFP_UCODE_SIZE];
