2008-08-04powerpc: Move include files to arch/powerpc/include/asmStephen Rothwell
from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-08-01dual license ftrace.txtSteven Rostedt
I asked legal about the licensing of ftrace.txt, and they told me that, unless the Documentation directory is specifically set up to handle non GPL licenses (which it does not appear to be), then it would be best to put ftrace.txt under the GPL. This patch adds a dual license to ftrace.txt such that it is under both the FDL and the GPL.

2008-08-01kgdb: fix kgdb_validate_break_address to perform a mem writeJason Wessel
A regression to the kgdb core was found in the case of using the CONFIG_DEBUG_RODATA kernel option. When this option is on, a breakpoint cannot be written into any readonly memory page. When an external debugger requests a breakpoint to get set, the kgdb_validate_break_address() was only checking to see if the address to place the breakpoint was readable and lacked a write check. This patch changes the validate routine to try reading (via the breakpoint set request) and also to try immediately writing the break point. If either fails, an error is correctly returned and the debugger behaves correctly. Then an end user can make the descision to use hardware breakpoints. Also update the documentation to reflect that using CONFIG_DEBUG_RODATA will inhibit the use of software breakpoints. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>
2008-08-01kgdb: remove the requirement for CONFIG_FRAME_POINTERJason Wessel

2008-07-31[PATCH] configfs: Convenience macros for attribute definition.Joel Becker
Sysfs has the _ATTR() and _ATTR_RO() macros to make defining extended form attributes easier. configfs should have something similiar. - _CONFIGFS_ATTR() and _CONFIGFS_ATTR_RO() are the counterparts to the sysfs macros. - CONFIGFS_ATTR_STRUCT() creates the extended form attribute structure. - CONFIGFS_ATTR_OPS() defines the show_attribute()/store_attribute() operations that call the show()/store() operations of the extended form configfs_attributes.

2008-07-29lguest: turn Waker into a thread, not a processRusty Russell
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).

2008-07-29lguest: Adaptive timeoutRusty Russell
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>
2008-07-29lguest: Tell Guest net not to notify us on every packet xmitRusty Russell
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).

2008-07-29lguest: virtio-rng supportRusty Russell

2008-07-29lguest: Support assigning a MAC addressMark McLoughlin
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 ...
