2007-10-23Clocksource is continuous regardless of the state of the host's TSC.Tony Breeds
Currently lguest will spend a lot of of time waking up the host, as it cannot go tickless (if the [host] TSC has been marked unstable). On my laptop I was getting ~40% of wakeups from lguest. With this patch applied, my laptop is much happier! Signed-off-by: Tony Breeds <tony@bakeyournoodle.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2007-10-23lguest_devices belongs in lguest_bus.c: it's not i386-specific.Rusty Russell
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2007-10-23Make lguest_launcher.h types userspace-friendlyRusty Russell
lguest_launcher.h uses "u32" not "__u32", which sets a bad example. Fix that, and include <linux/types.h>. This means we need to use -I on the Launcher build line so types.h is found. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2007-10-23lguest.txt updateRusty Russell
o Describe the new split configurations o Highlight code documentation in drivers/lguest/README o Point out necessity of having a getty on /dev/hvc0 o Remove gratuitous "m" in example o Don't discuss I/O model here, stick to user documentation. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Use copy_to_user() when copying a struct timespec to the guest - put_user() cannot handle two long's in one go on a 64bit arch. Signed-off-by: Jes Sorensen <jes@sgi.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Jes Sorensen <jes@sgi.com> Cc: Al Viro <viro@ftp.linux.org.uk>
2007-10-23turn err into errx in lguest call sitesGlauber de Oliveira Costa
These two callsites should really be errx instead of err, since there is no errno associated with them in the moment they are issued. Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Glauber de Oliveira Costa <gcosta@redhat.com>
2007-10-23Remove binfmts.h include from lg.hRusty Russell
It wasn't needed since a very early prototype of lguest. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2007-10-23Make asm-x86/bootparam.h includable from userspace.Rusty Russell
To actually write a bootloader (or, say, the lguest launcher) currently requires duplication of these structures. Making them includable from userspace is much nicer. We merge the common userspace-required definitions of e820_32/64.h into e820.h for export. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Commit 238e4f142c33bb34440cc64029dde7b9fbc4e65f ("ide: add IDE_HFLAG_NO_LBA48 and IDE_HFLAG_NO_LBA48_DMA host flags") caused a regression because the host_flags in struct hwif_s wasn't expanded to cope with the fact that the host flags no longer fit in 16 bits.

2007-10-22ppc: fix AT_VECTOR_SIZE on arch/ppcGrant Likely
Commit 4f9a58d75bfe82ab2b8ba5b8506dfb190a267834 ("increase AT_VECTOR_SIZE to terminate saved_auxv properly") changes the size of AT_VECTOR_SIZE from hard coded '44' to a calculation based on the value of AT_VECTOR_SIZE_ARCH and AT_VECTOR_SIZE_BASE. The change works for arch/powerpc, but it breaks arch/ppc because the needed AT_VECTOR_SIZE_ARCH is not present in include/asm-ppc/system.h and a default value of 0 is used instead. This results in AT_VECTOR_SIZE being too small and it causes a kernel crash on loading init.

2007-10-22[MIPS] time: SMP-proofing of Sibyte clockevent/clocksource code.Ralf Baechle
The BCM148 has 4 cores but there are also just 4 generic timers available so use the ZBbus cycle counter instead of it. In addition the ZBbus counter also offers a much higher resolution and 64-bit counting so I'm considering a later complete conversion to it once I figure out if all members of the Sibyte SOC family support it - the docs seem to agree but the headers files seem to disagree ...

2007-10-22Change table chaining layoutJens Axboe
Change the page member of the scatterlist structure to be an unsigned long, and encode more stuff in the lower bits: - Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located at sg + 1. - Bit 0 set: this is a chain entry, the next real entry is at ->page_link with the two low bits masked off. - Bit 1 set: this is the final entry in the sg entry. sg_next() will return NULL when passed such an entry. It's thus important that sg table users use the proper accessors to get and set the page member. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
