2008-11-13ETRAX-FS: Don't schedule DMA processing without active channels.edgar_igl

2008-11-12Implement LSI53C895A quirks exposed by OpenServer (Justin Chevrier).balrog
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

2008-11-11Reintroduce migrate-to-exec: support (Charles Duffy)aliguori
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. This version of the patch refactors now-common code from migrate-tcp.c into migrate.c.

Generate an option rom instead of using a hijacked boot sector for kernel booting.

2008-11-05Add KVM support to QEMUaliguori
This patch adds very basic KVM support. KVM is a kernel module for Linux that allows userspace programs to make use of hardware virtualization support. It current supports x86 hardware virtualization using Intel VT-x or AMD-V. It also supports IA64 VT-i, PPC 440, and S390. This patch only implements the bare minimum support to get a guest booting. It has very little impact the rest of QEMU and attempts to integrate nicely with the rest of QEMU. Even though this implementation is basic, it is significantly faster than TCG. Booting and shutting down a Linux guest: w/TCG: 1:32.36 elapsed 84% CPU w/KVM: 0:31.14 elapsed 59% CPU Right now, KVM is disabled by default and must be explicitly enabled with -enable-kvm. We can enable it by default later when we have had better testing.

2008-10-31Implement "info chardev" command. (Gerd Hoffmann)aliguori
This patch makes qemu keep track of the character devices in use and implements a "info chardev" monitor command to print a list. qemu_chr_open() sticks the devices into a linked list now. It got a new argument (label), so there is a name for each device. It also assigns a filename to each character device. By default it just copyes the filename passed in. Individual drivers can fill in something else though. qemu_chr_open_pty() sets the filename to name of the pseudo tty allocated. Output looks like this: (qemu) info chardev monitor: filename=unix:/tmp/run.sh-26827/monitor,server,nowait serial0: filename=unix:/tmp/run.sh-26827/console,server serial1: filename=pty:/dev/pts/5 parallel0: filename=vc:640x480 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5575 c046a42c-6fe2-441c-8c8c-71466251a162
2008-10-31Make DMA bottom-half driven (v2)aliguori
The current DMA routines are driven by a call in main_loop_wait() after every select. This patch converts the DMA code to be driven by a constantly rescheduled bottom half. The advantage of using a scheduled bottom half is that we can stop scheduling the bottom half when there no DMA channels are runnable. This means we can potentially detect this case and sleep longer in the main loop. The only two architectures implementing DMA_run() are cris and i386. For cris, I converted it to a simple repeating bottom half. I've only compile tested this as cris does not seem to work on a 64-bit host. It should be functionally identical to the previous implementation so I expect it to work. For x86, I've made sure to only fire the DMA bottom half if there is a DMA channel that is runnable. The effect of this is that unless you're using sb16 or a floppy disk, the DMA bottom half never fires. You probably should test this malc. My own benchmarks actually show slight improvement by it's possible the change in timing could affect your demos. Since v1, I've changed the code to use a BH instead of a timer. cris at least seems to depend on faster than 10ms polling.

2008-10-17scsi-generic: correct error managementaurel32
this patch allows to fully use a tape device connected to qemu through the scsi-generic interface. Previous patch introduced tape SCSI commands management, this one improve error case management: - the SCSI controller command completion must be called with the status value, not the sense value. In the case of scsi-generic, the SCSI status is given by the field status of sg_io_hdr_t (the value is left shifted by one regarding status codes defined in /usr/include/scsi/scsi.h) - when a read is aborted due to a mark/EOF/EOD/EOM, the len reported to controller can be 0. LSI controller emulation doesn't know how to manage this. A workaround found is to call the completion routine with SCSI_REASON_DONE just after calling it with SCSI_REASON_DATA with len=0. This patch also manages correctly the block size of the tape device. This patch has been tested with a real tape device "HP C5683A", linux guest (debian etch) and tools like "mt", "tar" and "btape". Windows guest is not better supported than before...
