2008-11-14target-alpha: implement getxuid and getxgid syscallsaurel321-0/+24
This patch implemented the setxuid and setxgid syscalls for Alpha. These syscalls return two values, both uid/euid and gid/egid. In addition to returning the first value in $v0, the additional value is returned in the $a4 register. The syscalls are used instead of the separate syscalls for those values used on other architectures (this is probably because Alpha Linux started out syscall compatible with DEC/OSF/Tru64). With this patch, the perlbmk benchmarks from Spec2000 run properly. (Vince Weaver) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5722 c046a42c-6fe2-441c-8c8c-71466251a162

2008-11-12Implement LSI53C895A quirks exposed by OpenServer (Justin Chevrier).balrog1-2/+22
After going through the debug log and scratching my head for quite some time. I found the following: The problem was with this block move: lsi_scsi: SCRIPTS dsp=0fae8e50 opcode 01000028 arg 00f63c40 lsi_scsi: DMA addr=0x00f63c40 len=36 The number of bytes to be transferred (len) should be 40 which corresponds to the block transfer of length 0x28 (from opcode 01000028). Instead we have a length of 36 (0x24). The code responsible for this is (in 'lsi_do_dma'): if (count > s->current_dma_len) count = s->current_dma_len; Basically we're overwriting the length 40 with the value 36 which I think we just left over in that variable from an earlier transfer. In my patch below I initialize s->current_dma_len to s->dbc before we begin the DMA transfer during Data In phase. The attached patch gets Openserver 5.0.5 past the hardware detection (and it lists the hard drive to boot, woohoo). It appears to stop a little while later (doesn't seem SCSI related), but it's been so long since I've booted Openserver I'm not sure what's supposted to happen after the HW detection using the boot/root disks. Props go to Craig Ringer for the initial post and the code that he posted some of which is in this patch. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5706 c046a42c-6fe2-441c-8c8c-71466251a162

2008-11-11sockets: switch over tcp/telnet/unix serial line to new helper functions ↵aliguori1-74/+32
(Gerd Hoffman) This switches the tcp, telnet and unix socket support for character devices (serial/parallel, ...) to the new socket helpers. Thereby they gain IPv6 support and also get ability to search for a free tcp port. Syntax is the same as for vnc, using a to= option, like this: -serial tcp:localhost:5000,to=5099,server This will check the 5000 -> 5099 port range (inclusive) for a free tcp port. Likewise you can get auto-allocated unix sockets by specifying an empty path: -serial unix:,server qemu will create a randomly named socket in $TMPDIR then. tcp also got new "ipv4" and "ipv6" options to make qemu try only the specified internet protocol version. You can use the "info chardev" command added by the first patch in this series to figure the tcp port / unix socket actually allocated.

This patch switches the vnc code ofer to the new socket helper functions. It adds support IPv6 support and for automatically allocating an unused vnc display port. The latter is handled ising a to= option, specifying the upper limit for the display number to try. Scanning is started at the display number given in the display specification, i.e. this command line: -vnc localhost:7,to=11 will try displays 7 to 11 (inclusive). There are also new "ipv4" and "ipv6" options to make qemu try only the specified internet protocol version. The display actually allocated can be queried using the "info vnc" monitor command.

2008-11-11Reintroduce migrate-to-exec: support (Charles Duffy)aliguori7-171/+453
KVM's live migration support included support for exec: URLs, allowing system state to be written or received via an arbitrary popen()ed subprocess. This provides a convenient way to pipe state through a compression algorithm or an arbitrary network transport on its way to its destination, and a convenient way to write state to disk; libvirt's qemu driver currently uses migration to exec: targets for this latter purpose.

2008-11-11target-mips: convert bitfield ops to TCGaurel323-46/+41
Bitfield operations can be written with very few TCG instructions (between 2 and 5), so it is worth converting them to TCG. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5678 c046a42c-6fe2-441c-8c8c-71466251a162
2008-11-11target-mips: optimize gen_op_addr_add() (2/2)aurel323-16/+13
Instead of dynamically generating different code depending on the UX flag, add a new flag in ctx->flags to generate different code. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5677 c046a42c-6fe2-441c-8c8c-71466251a162
