* pcmcia: deprecate CS_NO_MORE_ITEMSDominik Brodowski2008-08-22
| | | | | | | | | | | | CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if the end of a tuple chain is reached. As at least one PCMCIA driver relies on matching this return value, replace it with -ENOSPC which is now uniquely used for this purpose within the in-kernel pcmcia subsystem.

| | | | | | | This error code meant that trying to change the configuration after the initialization phase is forbidden. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
* pcmcia: deprecate CS_BAD_HANDLEDominik Brodowski2008-08-22
| | | | | | | | CS_BAD_HANDLE means that something went badly wrong: no parameter was passed, or the paramater passed wasn't the correct one. Therefore, replace it with -EINVAL. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

| * lguest: turn Waker into a thread, not a processRusty Russell2008-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | lguest uses a Waker process to break it out of the kernel (ie. actually running the guest) when file descriptor needs attention. Changing this from a process to a thread somewhat simplifies things: it can directly access the fd_set of things to watch. More importantly, it means that the Waker can see Guest memory correctly, so /dev/vring file descriptors will work as anticipated (the alternative is to actually mmap MAP_SHARED, but you can't do that with /dev/zero).

| * lguest: Adaptive timeoutRusty Russell2008-07-28
| | | | | | | | | | | | | | | | | | | | | | | | Since the correct timeout value varies, use a heuristic which adjusts the timeout depending on how many packets we've seen.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | virtio_ring has the ability to suppress notifications. This prevents a guest exit for every packet, but we need to set a timer on packet receipt to re-check if there were any remaining packets. Here are the times for 1G TCP Guest->Host with different timeout settings (it matters because the TCP window doesn't grow big enough to fill the entire buffer): Timeout value Seconds Xmit/Recv/Timeout None (before) 25.3784 xmit 7750233 recv 1 2500 usec 62.5119 xmit 207020 recv 2 timeout 207020 1000 usec 34.5379 xmit 207003 recv 2 timeout 207003 750 usec 29.2305 xmit 207002 recv 1 timeout 207002 500 usec 19.1887 xmit 561141 recv 1 timeout 559657 250 usec 20.0465 xmit 214128 recv 2 timeout 214110 100 usec 19.2583 xmit 561621 recv 1 timeout 560153 (Note that these values are sensitive to the GSO patches which come later, and probably other traffic-related variables, so take with a large grain of salt).

Also, in Fedora, we have persistent network interface naming based on the MAC address, so with randomly assigned addresses you're soon going to hit eth13. Who knows what will happen then! Allow assigning a MAC address to the network interface with e.g. --tunnet=bridge:eth0:00:FF:95:6B:DA:3D or: --tunnet=192.168.121.1:00:FF:95:6B:DA:3D which is pretty unintelligable, but ...
