Transmit length is split into multiples of 4 bytes and the remainder is transmitted using TxD1/2/3. Also, a transmit on TxD1/2/3 needs a check for Tx empty before using TXD0 and vice versa. Towards this requirement, tx_fill_fifo is updated to fill only if tx length is greater than 4 bytes. For any length the remainder bytes is first pushed to TxD1/2/3 and enables interrupts to wait for tx empty interrupt and transfer the remaining in interrupt routine.

Otherwise, we may loop through the whole Tx BD list since "free" BDs always have the USED bit set. This should not result in an error since no LAST bit is found, but it eats up time. This issue was introduced by the commit "xilinx_emacps: Optimize the BD handling logic" on Jan 21, 2013. Note that there is no corresponding issue for the Rx BD list because its freecnt is 0.

The logic works the other way round: When a buffer becomes ready after reading TXSR, there is no reason why we shouldn't process it. This is similar to xemacps_rx_poll() where RXSR_FRAMERX isn't checked either. We do stop when no buffers are available, though. In this case, skip netif_start_queue() because nothing has changed.

| 167b3c7 | Thomas Betker | 11 May 2013, 09:10:40 UTC | xilinx_emacps: Handle NAPI "rotten packets" When xemacps_rx_poll() has processed the Rx BD ring until it is empty, another packet may come in before we have unmasked the Rx interrupts. No interrupt is signalled for it, and it is left to rot in the BD ring until the next packet is received. This is what NAPI calls a "rotting packet", and it actually seems to occur quite often in heavy traffic (about 30 times per second), sometimes leading to Rx stalls. The solution is standard: Check the Rx BD ring again after unmasking the Rx interrupts, and reschedule NAPI (and remask the interrupts) when a new packet is detected. Note that we no longer need an inner loop around xemacps_rx(); the latter returns when the BD list is empty or the budget is reached, so we are usually done. [Previously, xemacps_rx() would also return when XEMACPS_RECV_BD_CNT was reached, so we had to loop over it.] Signed-off-by: Thomas Betker <thomas.betker@rohde-schwarz.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com> | 05 June 2013, 08:48:44 UTC |

Without this, machine_shutdown() simply puts all CPUs into a loop. If the code of that loop is over-written, the CPUs may hang or crash (which I do observe in practice), or cause the kexec'd kernel not to be able to initialize them. This fix has the added benefit that the kexec always happens on the boot CPU, and thus kexec mirrors the initial kernel boot as much as possible.
