From: Adrian Schmutzler Date: Fri, 7 Aug 2020 13:58:52 +0000 (+0200) Subject: ath25: drop target X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7d29a557140381ef1815329f6843b88b4126d490;p=openwrt%2Fstaging%2Flynxis.git ath25: drop target This target still only works with kernel 4.14, and not so recent attempts of getting newer kernel versions supported did not lead to success. Therefore, drop the target, as we are already two LTS kernel versions ahead and it does not seem like anybody will pick up the work.

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");
