* Input: gpio-keys - simplify argument list for report_eventUwe Kleine-König2008-08-081-4/+5
| | | | | | | | | | For now this only saves a few instructions (for gpio_keys_report_event, gpio_keys_isr and gpio_check_button one instraction each on ARM using arm-linux-gnu-gcc 4.2.3---I assume this is similar for other arch/compiler combinations).

* Input: ati_remote2 - add loadable keymap supportVille Syrjala2008-07-301-29/+101
| | | | | | | | | | | | Support for loadable keymaps. The driver now supports individual keymaps for each of the five modes (AUX1-AUX4 and PC) of the remote. To achieve this the keymap scancode is interpreted as a combination of the mode and actual button scancode. The original keycode patches were done by Peter Stokes <linux@dadeos.co.uk> but I modified it quite a lot. Signed-off-by: Ville Syrjala <syrjala@sci.fi> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

| * lguest: turn Waker into a thread, not a processRusty Russell2008-07-291-63/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Russell2008-07-291-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | Since the correct timeout value varies, use a heuristic which adjusts the timeout depending on how many packets we've seen. This gives slightly worse results, but doesn't need tweaking when GSO is introduced. 500 usec 19.1887 xmit 561141 recv 1 timeout 559657 Dynamic (278) 20.1974 xmit 214510 recv 5 timeout 214491 usec 278 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you've got a nice DHCP configuration which maps MAC addresses to specific IP addresses, then you're going to want to start your guest with one of those MAC addresses. 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 ...

| | | | | | | | | | | | | | | | | | Ron Minnich noticed that guest userspace gets a GPF when it tries to int3: we need to copy the privilege level from the guest-supplied IDT to the real IDT. int3 is the only common case where guest userspace expects to invoke an interrupt, so that's the symptom of failing to do this.
