2009-12-13gdbstub: add MIPS16 supportNathan Froyd
The only thing to do here is to expose the current processor mode to GDB and to set the processor mode properly when we change the PC. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-13target-mips: add mips16 instruction decodingNathan Froyd
There's no good way to add this incrementally, so we do it all at once. The only changes to shared code are in handle_delay_slot. We need to flip ISAMode when doing a jump-and-exchange. We also need to set ISAMode the low bit of the target address for jump-to-register. Also, since we're now adding bits that can be in MIPS_HFLAG_BMASK_EXT, make sure we use MIPS_HFLAG_BMASK_BASE in the places where we just want basic information about a branch.

2009-12-13target-mips: split out delay slot handlingNathan Froyd
Move delay slot handling to common code whose invocation can be controlled from gen_intermediate_code_internal. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-13target-mips: add gen_base_offset_addrNathan Froyd
This is a common pattern in existing code. We'll also use it to implement the mips16 SAVE/RESTORE instructions. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-12-13target-mips: move ROTR and ROTRV inside gen_shift_{imm, }Nathan Froyd
It's easier to implement mips16 shift instructions if we're not examining the opcode inside gen_shift_{imm,}. So move ROTR and ROTRV and do the special-case handling of SRL and SRLV inside decode_opc. Likewise for their 64-bit counterparts.

2009-12-13target-mips: change interrupt bits to be mips16-awareNathan Froyd
We need to stash the operating mode into the low bit of the error PC and restore it on return from interrupts. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-13target-mips: add new HFLAGs for JALX and 16/32-bit delay slotsNathan Froyd
We create separate masks for the "basic" branch hflags and the "extended" branch hflags and define MIPS_HFLAG_BMASK as the logical or of those two. This is done to avoid churning the codebase in lots of different places. We also make the execution mode an hflag under MIPS_HFLAG_TMASK Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-13workaround for cmd646 bmdma register access while no dma is activeIgor V. Kovalenko
This is a workaround only, and is a partial revert of a few changes to BMDMAState which removed pci_dev field on the way. - cmd646 pci_from_bm() expects bm->unit value to correspond with bm data being passed to callback as opaque pointer. This breaks when write to dma control register of second channel happens when no dma operation is in progress, so bm->unit is zero for second channel, and pci_from_bm() returns garbage pointer. Crash happens shortly after that while dereferencing that pointer. v0->v1: cleaned up dead code from pci_from_bm. Signed-off-by: Igor V.

According to the SCSI-2 specification, http://ldkelley.com/SCSI2/SCSI2/SCSI2/SCSI2-08.html#8.2.5 , "if the allocation length of the command descriptor block (CDB) is too small to transfer all of the parameters, the additional length shall not be adjusted to reflect the truncation."

2009-12-12v2: properly save kvm system time msr registersGlauber Costa
Currently, the msrs involved in setting up pvclock are not saved over migration and/or save/restore. This patch puts their value in special fields in our CPUState, and deal with them using vmstate. kvm also has to account for it, by including them in the msr list for the ioctls.

2009-12-12VNC: Convert do_info_vnc() to QObjectLuiz Capitulino
Return a QDict with server information. Connected clients are returned as a QList of QDicts. The new functions (vnc_qdict_remote_addr(), vnc_qdict_local_addr() and put_addr_qdict()) are used to insert 'host' and 'service' information in the returned QDict.

Return a QDict, which may contain up to more two QDicts, depending on the type of migration we're performing. IMPORTANT: as a QInt stores a int64_t integer, RAM values are going to be stored as int64_t and not as uint64_t as they are today. If this is a problem QInt will have to be changed.

2009-12-12vnc: fix capslock tracking logic.Gerd Hoffmann
The capslock tracking logic added by commit 6b1325029d80455b9da7cd7bd84a88cb915b867c doesn't work correctly for vnc clients without EXT_KEY_EVENT support. The reason is that qemu converts keysyms for letters to lowercase for the keysym2scancode lookup. It then also passes the lowercase value down to do_key_event(), but the capslock tracking code needs it with the correct case to work properly. This patch adds a new variable for the lowercase keysym so we'll keep the unmodified value for do_key_event(). The keysym2scancode is not needed with EXT_KEY_EVENT capable clients like any app based on the gtk-vnc widget, so I missed that case in testing ...

2009-12-12scsi: fix drive hotplug.Gerd Hoffmann
This patch fills the DriveInfo->unit after hotplugging a scsi disk. It makes a difference when auto-assigning a scsi id, where unit was left filled with '-1' instead of the actual scsi id. With this patch applied the the drive naming logic in drive_init() works as good as it did in previous releases. Which means it works fine with a single scsi bus.

2009-12-12pci: don't hw_error() when no slot is available.Gerd Hoffmann
Current PCI code will simply hw_error() and thus abort in case no free PCI slot is available or the requested PCI slot is already in use by another device. For the hotplug case this behavior is not acceptable. This patch makes qemu pass up the error properly, so the calling code can decide whenever it wants to exit with an error (on startup) or whenever it wants to continue (hotplug).

2009-12-12pci: don't abort() when trying to hotplug with acpi off.Gerd Hoffmann
The PCI bus on x86 requires ACPI for hotplug support, thus disbling ACPI also disables hotplug for the PCI bus. This patch makes qemu check whenever the PCI bus in question can handle hotplug before trying to add devices. This is needed because qdev will abort() on any attempt to hotplug devices into a non-hotpluggable bus.

2009-12-12Set default console to virtio on S390xGerd Hoffmann
All "normal" system emulation targets in qemu I'm aware of display output on either VGA or serial output. Our S390x virtio machine doesn't have such kind of legacy hardware. So instead we need to default to a virtio console. Add flags to QEMUMachine to indicate which kind of default devices make sense for the machine in question.
