POLL should not enable IRQ when work is not completed -2. No locking between TX descriptor cleaning and XMIT descriptor handling -3. No locking between RX POLL and XMIT modifying control register -4. Since TX cleaning (called from POLL) is running in parallel with XMIT - unnecessary locking is needed. -5. IRQ handler looks at RX frame status solely, this is wrong when IRQ is - temporarily disabled (in POLL), and when IRQ is shared. -6. IRQ handler clears IRQ status, which is unnecessary -7. TX queue was stopped in preventing cause when not MAX_SKB_FRAGS+1 descriptors - were available after a SKB been scheduled by XMIT. Instead the TX queue is - stopped first when not enough descriptors are available upon entering XMIT. - -It was hard to split up this patch in smaller pieces since all are tied -together somehow. - -Note the RX flag used in the interrupt handler does not signal that interrtupt -was asserted, but that a frame was received. Same goes for TX. Also, IRQ is not -asserted when the RX flag is set before enabling IRQ enable until a new frame is -received. So extra care must be taken to avoid enabling IRQ and all descriptors -are already used, hence dead lock will upon us. See new POLL implementation that -enableds IRQ then look at the RX flag to determine if one or more IRQs may have -been missed. TX/RX flags are cleared before handling previously enabled -descriptors, this ensures that the RX/TX flags are valid when determining if IRQ -should be turned on again. - -By moving TX cleaning from POLL to XMIT in the standard case, removes some -locking trouble. Enabling TX cleaning from poll only when not enough TX -descriptors are available is safe because the TX queue is at the same time -stopped, thus XMIT will not be called. The TX queue is woken up again when -enough descriptrs are available. - -TX Frames are always enabled with IRQ, however the TX IRQ Enable flag will not -be enabled until XMIT must wait for free descriptors. - -Locking RX and XMIT parts of the driver from each other is needed because the -RX/TX enable bits share the same register. - -Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> ---- - drivers/net/greth.c | 158 ++++++++++++++++++++++++++++++--------------------- - 1 files changed, 93 insertions(+), 65 deletions(-) - ---- a/drivers/net/greth.c -+++ b/drivers/net/greth.c -@@ -1,7 +1,7 @@ - /* - * Aeroflex Gaisler GRETH 10/100/1G Ethernet MAC. - * -- * 2005-2009 (c) Aeroflex Gaisler AB -+ * 2005-2010 (c) Aeroflex Gaisler AB - * - * This driver supports GRETH 10/100 and GRETH 10/100/1G Ethernet MACs - * available in the GRLIB VHDL IP core library. -@@ -401,12 +401,20 @@ greth_start_xmit(struct sk_buff *skb, st - struct greth_private *greth = netdev_priv(dev);
