      radeon: Deinline indirect register accessor functions · 9e5acbc2
      Denys Vlasenko 提交于
      This patch deinlines indirect register accessor functions.
      
      These functions perform two mmio accesses, framed by spin lock/unlock.
      Spin lock/unlock by itself takes more than 50 cycles in ideal case
      (if lock is exclusively cached on current CPU).
      
      With this .config: http://busybox.net/~vda/kernel_config,
      after uninlining these functions have sizes and callsite counts
      as follows:
      
      r600_uvd_ctx_rreg: 111 bytes, 4 callsites
      r600_uvd_ctx_wreg: 113 bytes, 5 callsites
      eg_pif_phy0_rreg: 106 bytes, 13 callsites
      eg_pif_phy0_wreg: 108 bytes, 13 callsites
      eg_pif_phy1_rreg: 107 bytes, 13 callsites
      eg_pif_phy1_wreg: 108 bytes, 13 callsites
      rv370_pcie_rreg: 111 bytes, 21 callsites
      rv370_pcie_wreg: 113 bytes, 24 callsites
      r600_rcu_rreg: 111 bytes, 16 callsites
      r600_rcu_wreg: 113 bytes, 25 callsites
      cik_didt_rreg: 106 bytes, 10 callsites
      cik_didt_wreg: 107 bytes, 10 callsites
      tn_smc_rreg: 106 bytes, 126 callsites
      tn_smc_wreg: 107 bytes, 116 callsites
      eg_cg_rreg: 107 bytes, 20 callsites
      eg_cg_wreg: 108 bytes, 52 callsites
      
      Functions r100_mm_rreg() and r100_mm_rreg() have a fast path and
      a locked (slow) path. This patch deinlines only slow path.
      
      r100_mm_rreg_slow: 78 bytes, 2083 callsites
      r100_mm_wreg_slow: 81 bytes, 3570 callsites
      
      Reduction in code size is more than 65,000 bytes:
      
          text     data      bss       dec     hex filename
