2008-11-19Fix media detection on emulated CDROM (Gary Grebus)aliguori1-1/+3
This patch tweaks the ATAPI CDROM emulation to fix an annoyance seen when running a variety of Linux guests: the desktop GUI shows a CDROM device as present, but is unable to automount the media and display its contents. The patch adds the PLAY_AUDIO capability bit to the data returned by MODE_SENSE commands. That convinces the guest kernel to determine what kind of media is present. Arguably Linux could be smarter about this, but it's my guess there are few (if any) hardware CDROM drives that don't set the bit, and there are a large number of Linux distros that exhibit this problem.

2008-11-18x86: Debug register emulation (Jan Kiszka)aliguori5-42/+217
Built on top of previously enhanced breakpoint/watchpoint support, this patch adds full debug register emulation for the x86 architecture. Many corner cases were considered, and the result was successfully tested inside a Linux guest with gdb, but I won't be surprised if one or two scenarios still behave differently in reality.

2008-11-18Introduce BP_CPU as a breakpoint type (Jan Kiszka)aliguori2-8/+39
Add another breakpoint/watchpoint type to BP_GDB: BP_CPU. This type is intended for hardware-assisted break/watchpoint emulations like the x86 architecture requires. To keep the highest priority for BP_GDB breakpoints, this type is always inserted at the head of break/watchpoint lists, thus is found first when looking up the origin of a debug interruption.

2008-11-18gdbstub: manage CPUs as threads (Jan Kiszka)aliguori3-82/+196
This patch enhances QEMU's built-in debugger for SMP guest debugging. Using the thread support of the gdb remote protocol, each VCPU is mapped on a pseudo thread and exposed to the gdb frontend. This way you can easy switch the focus of gdb between the VCPUs and observe their states. On breakpoint hit, the focus is automatically adjusted just as for normal multi-threaded application under gdb control. Furthermore, the patch propagates breakpoint and watchpoint insertions or removals to all CPUs, not just the current one as it was the case so far. Without this, SMP guest debugging was practically unfeasible.

2008-11-18Refactor and enhance break/watchpoint API (Jan Kiszka)aliguori13-183/+267
This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the succeeding enhancements this series comes with. First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching to dynamically allocated data structures that are kept in linked lists. This also allows to return a stable reference to the related objects, required for later introduced x86 debug register support. Breakpoints and watchpoints are stored with their full information set and an additional flag field that makes them easily extensible for use beyond pure guest debugging.

This patch refactors the way the CPU state is handled that is associated with a TB. The basic motivation is to move more arch specific code out of generic files. Specifically the long #ifdef clutter in tb_find_fast() has to be overcome in order to avoid duplicating it for the gdb watchpoint fixes (patch "Restore pc on watchpoint hits").

KVM keeps track of physical memory based on slots in the kernel. The current code that translates QEMU memory mappings to slots work but is not robust in the fact of reregistering partial regions of memory. This patch does the right thing for reregistering partial regions of memory. It also prevents QEMU from using KVM private slots.

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).

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
