However -+ * the rx rings do not need to contain a static number of buffer -+ * descriptors, thus it makes sense to move the memory allocation out -+ * of the main interrupt handler and do it in a bottom half handler -+ * and only allocate new buffers when the number of buffers in the -+ * ring is below a certain threshold. In order to avoid starving the -+ * NIC under heavy load it is however necessary to force allocation -+ * when hitting a minimum threshold. The strategy for alloction is as -+ * follows: -+ * -+ * RX_LOW_BUF_THRES - allocate buffers in the bottom half -+ * RX_PANIC_LOW_THRES - we are very low on buffers, allocate -+ * the buffers in the interrupt handler -+ * RX_RING_THRES - maximum number of buffers in the rx ring -+ * -+ * One advantagous side effect of this allocation approach is that the -+ * entire rx processing can be done without holding any spin lock -+ * since the rx rings and registers are totally independent of the tx -+ * ring and its registers. This of course includes the kmalloc's of -+ * new skb's. Thus start_xmit can run in parallel with rx processing -+ * and the memory allocation on SMP systems. -+ * -+ * Note that running the skb reallocation in a bottom half opens up -+ * another can of races which needs to be handled properly. In -+ * particular it can happen that the interrupt handler tries to run -+ * the reallocation while the bottom half is either running on another -+ * CPU or was interrupted on the same CPU. To get around this the -+ * driver uses bitops to prevent the reallocation routines from being -+ * reentered. -+ * -+ * TX handling can also be done without holding any spin lock, wheee -+ * this is fun! since tx_csm is only written to by the interrupt -+ * handler. -+ */ -+ -+/** -+ * Threshold values for RX buffer allocation - the low water marks for -+ * when to start refilling the rings are set to 75% of the ring -+ * sizes. It seems to make sense to refill the rings entirely from the -+ * intrrupt handler once it gets below the panic threshold, that way -+ * we don't risk that the refilling is moved to another CPU when the -+ * one running the interrupt handler just got the slab code hot in its -+ * cache. -+ */ -+#define RX_RING_SIZE AR2313_DESCR_ENTRIES -+#define RX_PANIC_THRES (RX_RING_SIZE/4) -+#define RX_LOW_THRES ((3*RX_RING_SIZE)/4) -+#define CRC_LEN 4 -+#define RX_OFFSET 2 -+ -+#if defined(CONFIG_VLAN_8021Q) || defined(CONFIG_VLAN_8021Q_MODULE) -+#define VLAN_HDR 4 -+#else -+#define VLAN_HDR 0 -+#endif -+ -+#define AR2313_BUFSIZE (AR2313_MTU + VLAN_HDR + ETH_HLEN + CRC_LEN + \ -+ RX_OFFSET) -+ -+#ifdef MODULE -+MODULE_LICENSE("GPL");
