【无线】【流程】QCA无线驱动收包流程分析

概述：

无线驱动的收包过程是基于中断的处理方式。在准备接收数据之前，驱动需要先进行初始化接收数据使用到的相关结构（ sc_rxbuf和rxfifo ）。当数据包到达时，硬件会首先进行 DMA，完成以后产生Rx中断。中断处理过程又分为两个部分，首先是立即执行的上半段处理，负责将数据包从软件接收缓冲队列中取出，并补全接收缓冲区，以便继续接收数据；然后就是一个 tasklet机制的调度，进行数据包的分析处理，在 LMAC层中进行接收状态的分析和填充，在 UMAC层中对数据包本身进行分析，包括重组和包头转换等，最后将其转换为以太网帧的形式提交到 bridge上去。

中断开始

内核活动中有硬件中断和软件中断，对于无线网卡收包的第一步，是硬件中断，对于中断，内核中执行专门的例程，又叫中断处理程序，执行中断发生时的动作。中断处理可通过request_irq进行注册。

跟踪无线收包流程，就从中断处理开始：

error = request_irq(dev->irq, ath_isr, IRQF_DISABLED, dev->name, dev);

然后主要的目光集中在中断处理函数ath_isr中：

ath_rx_buf_link_aponly<--ath_rx_addbuffer_aponly<--ath_rx_intr_aponly<--ath_rx_edma_intr_aponly<--ath_common_intr_aponly<--ath_intr_aponly<--ath_isr_aponly<--do_ath_isr<--ath_isr

可以按照这个函数调用轨迹去看处理的过程，不详细说，重点集中在函数ath_rx_intr_aponly中

void ath_rx_intr_aponly(ath_dev_t dev, HAL_RX_QUEUE qtype)
{
    struct ath_softc *sc = ATH_DEV_TO_SC(dev);
    struct ath_rx_edma *rxedma;
    wbuf_t wbuf;
    struct ath_buf *bf;

struct ath_rx_status *rxs;
    HAL_STATUS retval;
    struct ath_hal *ah = sc->sc_ah;
    int    frames;

rxedma = &sc->sc_rxedma[qtype];

do {
          printk("%s %d receive packet %d \r\n", __func__, __LINE__, rxedma->rxfifoheadindex);
        wbuf = rxedma->rxfifo[rxedma->rxfifoheadindex];
        if (unlikely(wbuf == NULL))
            break;
        bf = ATH_GET_RX_CONTEXT_BUF(wbuf);

/*清理一下cache，则个是cache一致性问题后续说 */
        OS_SYNC_SINGLE(sc->sc_osdev,
                       bf->bf_buf_addr[0], sc->sc_rxstatuslen, BUS_DMA_FROMDEVICE,
                       OS_GET_DMA_MEM_CONTEXT(bf, bf_dmacontext));
        bf->bf_status |= ATH_BUFSTATUS_SYNCED;

rxs = bf->bf_desc;
#ifdef CONFIG_COMCERTO_CUSTOM_SKB_LAYOUT
        if (wbuf->mspd_data) {
            __memcpy(wbuf->data, wbuf->mspd_data, sc->sc_rxstatuslen + sizeof(struct ieee80211_qosframe) + ATH_COMCERTO_CUSTOM_SKB_OFFSET);
            wbuf->mspd_ofst = sc->sc_rxstatuslen + sizeof(struct ieee80211_qosframe) + ATH_COMCERTO_CUSTOM_SKB_OFFSET;
        }
#endif
        retval = ath_hal_rxprocdescfast(ah, NULL, 0, NULL, rxs, wbuf_raw_data(wbuf));
          /*ath_hal_rxprocdescfast = ar9300_proc_rx_desc_fast*/
#ifdef ATH_RX_DESC_WAR
        if (unlikely(HAL_EINVAL == retval))

{
               struct ath_buf *next_bf;
               wbuf_t next_wbuf;
               u_int32_t next_idx = rxedma->rxfifoheadindex;

bf->bf_status |= ATH_BUFSTATUS_WAR;

INCR(next_idx, rxedma->rxfifohwsize);
next_wbuf = rxedma->rxfifo[next_idx];

if (next_wbuf == NULL)
break;

next_bf = ATH_GET_RX_CONTEXT_BUF(next_wbuf);
               next_bf->bf_status |= ATH_BUFSTATUS_WAR;
               DPRINTF(sc, ATH_DEBUG_RX_PROC, "%s: Marking first DP 0x%x for drop\n",
                        __func__, (unsigned) bf->bf_buf_addr[0]);
               DPRINTF(sc, ATH_DEBUG_RX_PROC, "%s: Marking second DP 0x%x for drop\n",
                       __func__, (unsigned) next_bf->bf_buf_addr[0]);
          }
#endif
        /* XXX Check for done bit in RxS */
        if (HAL_EINPROGRESS == retval) {
            break;
        }

/* add this ath_buf for deferred processing, 将包放入到rxqueue，下半段部再处理*/
TAILQ_INSERT_TAIL(&rxedma->rxqueue, bf, bf_list);

/* clear this element before advancing */
rxedma->rxfifo[rxedma->rxfifoheadindex] = NULL;

/* advance the head pointer */
INCR(rxedma->rxfifoheadindex, rxedma->rxfifohwsize); /*处理下一个包*/

if (unlikely(rxedma->rxfifodepth == 0))
printk("ath_rx_intr: depth 0 PANIC\n");

rxedma->rxfifodepth--;
} while (TRUE);

/*将ath_bufs 从空闲的链表移到rxedma的rxfifo */

frames = rxedma->rxfifohwsize - rxedma->rxfifodepth;

if (frames > 0)
ath_rx_addbuffer_aponly(sc, qtype, frames);
}

这个函数主要做的就是将数据包从rxfifo中收上来，然后放入rxqueue，然后在空闲队列中找一个ath_bufs放回到rxfifo。

rxfifo

sc 中对应的rxfifo 有两个，分别对应于硬件的两个不同优先级的队列（ High-Priority 和Low-Priority ，HP长队16，LP长度128）

这两个参数在函数ar9300_fill_capability_info中的：

p_cap->hal_rx_hp_depth = HAL_HP_RXFIFO_DEPTH;

p_cap->hal_rx_lp_depth = HAL_LP_RXFIFO_DEPTH;

赋值；

通过枚举变量：

enum RX_FIFO_DEPTH {
HAL_HP_RXFIFO_DEPTH = 16,
HAL_LP_RXFIFO_DEPTH = 128,
};定义

rxfifo是指针的数组，在函数中申请了空间。

static int ath_rxfifo_alloc(struct ath_softc *sc, HAL_RX_QUEUE qtype)
{
struct ath_rx_edma *rxedma;
int bsize, error;

rxedma = &sc->sc_rxedma[qtype];

error = ath_hal_getrxfifodepth(sc->sc_ah, qtype, &rxedma->rxfifohwsize);
if (error)
return error;

bsize = sizeof(wbuf_t) * rxedma->rxfifohwsize;

printk("%s %d rxedma->rxfifohwsize = %d, bsize = %d\r\n", __func__, __LINE__, rxedma->rxfifohwsize, bsize);

上面在串口中打印结果是：

[2016:11:10:14:55:09][ 10.804000] ath_rxfifo_alloc 128 rxedma->rxfifohwsize = 16, bsize = 64

[2016:11:10:14:55:09][ 10.812000] ath_rxfifo_alloc 128 rxedma->rxfifohwsize = 128, bsize = 512

rxedma->rxfifo = (wbuf_t *)OS_MALLOC(sc->sc_osdev, bsize, GFP_KERNEL); /*所以这里申请的是存放指针的数组空间，这些指针就用来指向可用的ath_buf*/
if (rxedma->rxfifo == NULL)
return -ENOMEM;

rxedma->rxfifoheadindex = 0;
rxedma->rxfifotailindex = 0;
rxedma->rxfifodepth = 0;

OS_MEMZERO(rxedma->rxfifo, bsize);
TAILQ_INIT(&rxedma->rxqueue);
ATH_RXQ_LOCK_INIT(rxedma);

return 0;
}

sc->sc_rxbuf

sc_rxbuf 是整个驱动中，收包所使用的缓冲池，其中初始化了 512 个ath_buf 的对象。该结构为 LMAC 层提供空白的ath_buf结构。在在函数ath_rx_edma_init中初始化

int ath_rx_edma_init(ath_dev_t dev, int nbufs)

{

...

printk("%s %d: nbufs = %d, sc->sc_rxbufsize = %d\r\n", __func__, __LINE__, nbufs, sc->sc_rxbufsize);

/*串口输出： [2016:11:10:14:55:09][ 10.828000] ath_rx_edma_init 216: nbufs = 256, sc->sc_rxbufsize = 3900*/

for (i = 0; i < nbufs; i++, bf++, rxs++) {
     wbuf = ath_rxbuf_alloc(sc, sc->sc_rxbufsize);
     if (wbuf == NULL) {
          error = -ENOMEM;
          break;
     }

bf->bf_mpdu = wbuf;
bf->bf_buf_addr[0] = wbuf_map_single(sc->sc_osdev, wbuf, BUS_DMA_FROMDEVICE,
OS_GET_DMA_MEM_CONTEXT(bf, bf_dmacontext));

/*bf_buf_addr[0] 是物理地址，物理地址，物理地址，重要事情说三次, 这个地址在函数ath_rx_buf_link_aponly中写入MAC的寄存器：

ath_hal_putrxbuf(ah, bf->bf_buf_addr[0], qtype); /*ar9300_set_rx_dp*/

*/
ATH_SET_RX_CONTEXT_BUF(wbuf, bf);
bf->bf_desc = (void *)rxs;

TAILQ_INSERT_TAIL(&sc->sc_rxbuf, bf, bf_list); /*然后将bf加入到sc_rxbuf链的后面，就是说sc_rxbuf是有256个wbuf的链，这些buf就是free buf，用来接收数据包的*/
}

...

}

DMA是一种硬件机制，允许外围设备和主存之间直接传输他们的IO数据，而不需要系统处理器的参与。一个DMA映射就是要分配的DMA缓冲区与为该缓冲区生成的，设备可访问地址的组合。分为两种映射

一致性DMA映射和流式DMA映射，而无线驱动中使用的是流式DMA映射。

回到代码中，在初始化时使用了wbuf_map_single，其中的参数是BUS_DMA_FROMDEVICE

bf->bf_buf_addr[0] = wbuf_map_single(sc->sc_osdev, wbuf, BUS_DMA_FROMDEVICE,
OS_GET_DMA_MEM_CONTEXT(bf, bf_dmacontext));

wbuf_map_single调用了函数dma_map_single(devhandle->bdev, ptr, size, (direction == BUS_DMA_TODEVICE)? DMA_TO_DEVICE : DMA_FROM_DEVICE);

参考DMA-API.txt可以看到，函数dma_map_single用于映射处理的一段虚拟地址使得硬件设备可以直接访问并返回这段地址的物理地址；

Maps a piece of processor virtual memory so it can be accessed by the
device and returns the physical handle of the memory.

dma_addr_t dma_map_single(struct device *dev, void *ptr, size_t size,
enum dma_data_direction direction)
{
unsigned long addr = (unsigned long) ptr;

if (!plat_device_is_coherent(dev)) /*在kernel的配置文件中CONFIG_DMA_NONCOHERENT=y设置成y*/

__dma_sync(addr, size, direction);

return plat_map_dma_mem(dev, ptr, size);
}

linux/kernels/mips-linux-2.6.31/arch/mips/include/asm/mach-generic/dma-coherence.h

static inline dma_addr_t plat_map_dma_mem(struct device *dev, void *addr, size_t size)
{
return virt_to_phys(addr); /*这里返回的是物理地址*/
}

cache一致性

__dma_syn

a、DMA_TO_DEVICE：把cache的数据刷回内存里，用于使能dma传输到外设之前。因为dma传输只会从内存拿数据，所以必须把cache的数据全部刷回到内存中；

b、DMA_FROM_DEVICE：把cache的数据置无效，用于dma已经传输完毕产生中断之后，准备从内存读取到驱动的buffer中。如果不把cache的数据置无效，
那么cpu就会直接从cache中取出旧的数据，不会到内存中去拿新的数据；
c、DMA_BIDIRECTIONAL跟DMA_TO_DEVICE的效果一样

从串口可以看到，一次中断将硬件中128个包收上来，放到rxqueque，然后通过函数ath_rx_buf_link_aponly 向rxfifo回填了111个可用的wbuf。

下半段的收包通过tasklet机制完成
注册tasklet
ATH_INIT_TQUEUE(&osdev->intr_tq, (adf_os_defer_fn_t)ath_tasklet, (void*)dev);

tasklet的处理函数
ath_tasklet(TQUEUE_ARG data)
{
struct net_device *dev = (struct net_device *)data;
struct ath_softc_net80211 *scn = ath_netdev_priv(dev);
do_ath_handle_intr(scn->sc_dev);
}
函数调用过程
ieee80211_input->ieee80211_iter_input_all->ieee80211_input_all->ath_net80211_rx_aponly ->ath_rx_indicate_aponly->ath_rx_process_aponly->ath_rx_handler_aponly->do_ath_handle_intr

下半部的操作是在cpu的硬件中断（除了RXEOL, RXORN, SWBA，其他全部关闭）被关闭情况下进行的。
