2010-02-20tcg-sparc: Implement not.Richard Henderson
The fallback implementation of "ret = arg1 ^ -1" isn't ideal because of the extra tcg op to load the minus one. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-02-20tcg-sparc: Implement neg.Richard Henderson
The fallback implementation of "ret = 0 - arg1" isn't ideal, first because of the extra tcg op to load the zero, and second because we fail to handle zero as %g0 for arg1 of the sub. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-02-19qemu-img: Fix error messageKevin Wolf
When qemu-img can't open the new backing file for a rebase, it prints an error message which contains the file name of the old backing file. This is wrong, obviously. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-02-19qcow2: Fix access after end of arrayKevin Wolf
If a write requests crosses a L2 table boundary and all clusters until the end of the L2 table are usable for the request, we must not look at the next L2 entry because we already have arrived at the end of the array.

2010-02-19QEMU e820 reservation patchJes Sorensen
Hi, Kevin and I have agreed on the approach for this one now. So here is the latest version of the patch for QEMU, submitting e820 reservation entries via fw_cfg. Cheers, Jes Use qemu-cfg to provide the BIOS with an optional table of e820 entries. Notify the BIOS of the location of the TSS+EPT range to by reserving it via the e820 table. This matches a corresponding patch for Seabios, however older versions of Seabios will default to the hardcoded address range and stay compatible with current QEMU.

Since commit 98b19252cf1bd97c54bc4613f3537c5ec0aae263, all serial devices declare MULTIPORT feature. To allow 0.12 compatibility, we should clear this when max_nr_ports is 1.

2010-02-19USB HID does not support Set_IdleKevin O'Connor
I found that the QEMU USB keyboard support does not work properly with the Set_Idle command. Once a non-zero value is given to Set_Idle, then the keyboard reports an event on every poll - not based on the time issued in the Set_Idle command. I changed the code (see patch below) and it works for me. I'm not that familiar with the qemu internals, so I'm not sure if this is the best way to implement this feature. -Kevin Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-02-19mingw32: Enable C99/POSIX format stringsStefan Weil
Starting with mingw32-runtime 3.15, C99/POSIX format strings (%zu, %lld, ...) are supported by defining __USE_MINGW_ANSI_STDIO=1. As QEMU uses such format strings, unconditionally define this macro. It won't hurt on older revisions of mingw32-runtime. Tested with manually installed mingw32-runtime 3.15 on debian (cross compiled + wine).

2010-02-19Fix hanging user monitor when using balloon commandAdam Litke
Arghh... Adding missing S-O-B Hi Anthony. I wonder if there was a problem when importing my async command handler patchset. Since the 'balloon' command completes immediately, it must call the completion callback before returning. That call was missing but is added by the patch below.

2010-02-19Monitor: Report more than one error in handlersLuiz Capitulino
Handlers can generate only one error in a call, we let the programmer know if they brake this rule and clients will only get the first generated error. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-19Monitor: Debug stray prints the right wayLuiz Capitulino
QObject Monitor handlers should not call any Monitor print function: they should only build objects, printing is done by common code. Current QMP code will ignore such calls, as we can't send garbage to clients, additionally it will also emit an undefined error on the assumption that print calls usually report errors. However, the right way to deal with this is to rely on a return code. This has been fixed by other commit already. Now, this commit drops the error from monitor_vprintf() and adds a better debugging mechanism for those 'stray' prints: we count them if debug is enabled and let the developer know if a QObject handler is trying to print anything.

2010-02-19Monitor: Audit handler returnLuiz Capitulino
This commit verifies the following two rules specified by Markus Armbruster: 1. If the handler returns failure, it must have passed an error. If it didn't, it's broken. Report an internal error to the client, and report the bug to the programmer. 2. If the handler returns success, it must not have passed an error. If it did, it's broken. Report the error to the client, and report the bug to the programmer. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-19Monitor: Drop the print disabling mechanismLuiz Capitulino
We can ignore calls to monitor_vprintf() in QMP mode and use monitor_puts() directly in monitor_json_emitter(). This allows us to drop this ugly hack. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2010-02-19Monitor: Introduce cmd_new_ret()Luiz Capitulino
In order to implement the new error handling and debugging mechanism for command handlers, we need to change the cmd_new() callback to return a value. This commit introduces cmd_new_ret(), which returns a value and will be used only temporarily to handle the transition from cmd_new(). That is, as soon as all command handlers are ported to cmd_new_ret(), it will be renamed back to cmd_new() and the new error handling and debugging mechanism will be added on top of it.
