2008-11-20uImage: rename load_uboot() to load_uimage() (Hollis Blanchard)aliguori
u-boot is a firmware. uImage is an executable file format. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5764 c046a42c-6fe2-441c-8c8c-71466251a162
2008-11-20uImage: return base load address (Hollis Blanchard)aliguori
Return the base address at which the image was loaded so that callers may keep track of currently occupied guest memory. This will be required by the PPC 440 embedded code to avoid hard coding a device model/initrd location. Other users of this function could make use of this parameter to avoid hard coding these locations in the future too.

2008-11-19Make KVMSlot a real structurealiguori
struct kvm_userspace_memory_region does not use QEMU friendly types to define memory slots. This results in lots of ugly casting with warnings on 32-bit platforms. This patch introduces a proper KVMSlot structure that uses QEMU types to describe memory slots. This eliminates many of the casts and isolates the type conversions to one spot.

2008-11-19Fix media detection on emulated CDROM (Gary Grebus)aliguori
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)aliguori
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)aliguori
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)aliguori
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.

In order to provide accurate information about the triggering instruction, this patch adds the required bits to restore the pc if the access happened inside a TB.

2008-11-18Refactor and enhance break/watchpoint API (Jan Kiszka)aliguori
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.

2008-11-18Refactor translation block CPU state handling (Jan Kiszka)aliguori
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").

2008-11-18Make KVM slot management more robustaliguori
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.

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.
