66 | * CSR (control and status registers) | |
67 | * | |
68 | * CSR registers are mapped directly into PCI bus space, and are accessible | |
69 | * whenever platform supplies power to device, even when device is in | |
70 | * low power states due to driver-invoked device resets | |
71 | * (e.g. CSR_RESET_REG_FLAG_SW_RESET) or uCode-driven power-saving modes. | |
72 | * | |
841b2cca | 73 | * Use _il_wr() and _il_rd() family to access these registers; |
be663ab6 | 74 | * these provide simple PCI bus access, without waking up the MAC. |
0c1a94e2 | 75 | * Do not use il_wr() family for these registers; |
be663ab6 WYG |
76 | * no need to "grab nic access" via CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ. |
77 | * The MAC (uCode processor, etc.) does not need to be powered up for accessing | |
78 | * the CSR registers. | |
79 | * | |
80 | * NOTE: Device does need to be awake in order to read this memory | |
81 | * via CSR_EEPROM register | |
