2012-07-19monitor: remove unused do_info_traceHarsh Prateek Bora3-35/+0
Going forward with simpletrace v2 variable size trace records, we cannot have a generic function to print trace event info and therefore this interface becomes invalid. As per Stefan Hajnoczi: "This command is only available from the human monitor. It's not very useful because it historically hasn't been able to pretty-print events or show them in the right order (we use a ringbuffer but it prints them out from index 0). Therefore, I don't think we're under any obligation to keep this command around. No one has complained about it's limitations - I think this is a sign that no one has used it. I'd be okay with a patch that removes it."

2012-07-19trace: added ability to comment out events in the listAlexey Kardashevskiy1-0/+3
It is convenient for debug to be able to switch on/off some events easily. The only possibility now is to remove event name from the file completely and type it again when we want it back. The patch adds '#' symbol handling as a comment specifier. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>

2012-07-17build: fix build breakage due to bad mergeAnthony Liguori1-7/+4
34bb443ee74df3780d86044dbf6492eb798c5807 broke the build but in a subtle way. The patch on the ML was actually based on the 1.1.1 stable branch (accidentally). When I merged it from the ML, the fuzzing got resolved in a such a way that the newly introduced Makefile dependency on GENERATED_HEADERS got lost (that was not in 1.1.1). The dist bits also got duplicated (but this is just cosmetic). Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

All current users (IDE, SCSI and virtio-blk) happen to share this 20 characters limit. Still, it should be left to device models. They already enforce their limits. They have to, as the DriveInfo limit only affects legacy -drive serial=..., not the qdev properties. usb-storage, which doesn't limit serial number length, also uses DriveInfo for -usbdevice.

2012-07-17block: Geometry and translation hints are now useless, purge themMarkus Armbruster9-77/+12
There are two producers of these hints: drive_init() on behalf of -drive, and hd_geometry_guess(). The only consumer of the hint is hd_geometry_guess(). The callers of hd_geometry_guess() call it only when drive_init() didn't set the hints. Therefore, drive_init()'s hints are never used. Thus, hd_geometry_guess() only ever sees hints it produced itself in a prior call. Only the first call computes something, subsequent calls just repeat the first call's results. However, hd_geometry_guess() is never called more than once: the device models don't, and the block device is destroyed on unplug. Thus, dropping the repeat feature doesn't break anything now. If a block device wasn't destroyed on unplug and could be reused with a new device, then repeating old results would be wrong. Thus, dropping the repeat feature prevents future breakage. This renders the hints unused. Purge them from the block layer. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-07-17ide: qdev property for BIOS CHS translationMarkus Armbruster2-5/+6
This isn't quite orthodox. CHS translation is firmware configuration, communicated via the RTC's CMOS RAM, not a property of the disk. But it's best to treat it just like geometry anyway. Maintain backward compatibility exactly like for geometry: fall back to DriveInfo's translation, set with -drive trans=... Bonus: info qtree now shows the translation. Except when it shows "auto": that's resolved by pc_cmos_init_late(). To be addressed shortly. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2012-07-17hd-geometry: Clean up confusing use of prior translation hintMarkus Armbruster1-10/+7
When hd_geometry_guess() picks a geometry, it also picks the appropriate translation, but only when the prior translation hint is BIOS_ATA_TRANSLATION_AUTO. Looks wrong, because such a prior translation would be passed to the BIOS whether it's suitable for the geometry or not. Fortunately, that can't happen. There are just two ways for the translation hint to get set to something other than BIOS_ATA_TRANSLATION_AUTO: drive_init() on behalf of -drive trans=..., and hd_geometry_guess(). Both set it only when they also set a valid geometry hint, i.e. one with a non-zero number of cylinders. Since hd_geometry_guess() returns right away when it finds a valid geometry hint, translation can only be BIOS_ATA_TRANSLATION_AUTO in the remainder of the function. Assert this, and simplify accordingly. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
