Subsequent reads - * from higher addresses of the same register will read the latched - * value. Whenever the host writes part of such a register, the BIU - * collects the written value and does not write to the underlying - * register until all 4 dwords have been written. A similar buffering - * scheme applies to host access to the NIC's 64-bit SRAM. - * - * Access to different CSRs and 64-bit SRAM words must be serialised, - * since interleaved access can result in lost writes or lost - * information from read-to-clear fields. We use efx_nic::biu_lock - * for this. (We could use separate locks for read and write, but - * this is not normally a performance bottleneck.) - * - * The DMA descriptor pointers (RX_DESC_UPD and TX_DESC_UPD) are - * 128-bit but are special-cased in the BIU to avoid the need for - * locking in the host: - * - * - They are write-only. - * - The semantics of writing to these registers are such that - * replacing the low 96 bits with zero does not affect functionality. - * - If the host writes to the last dword address of such a register - * (i.e. the high 32 bits) the underlying register will always be - * written. If the collector and the current write together do not - * provide values for all 128 bits of the register, the low 96 bits - * will be written as zero. - * - If the host writes to the address of any other part of such a - * register while the collector already holds values for some other - * register, the write is discarded and the collector maintains its - * current state. - */ - -#if BITS_PER_LONG == 64 -#define EFX_USE_QWORD_IO 1 -#endif - -#ifdef EFX_USE_QWORD_IO -static inline void _efx_writeq(struct efx_nic *efx, __le64 value, - unsigned int reg) -{ - __raw_writeq((__force u64)value, efx->membase + reg);
