* sparc: fix floppy TC line setupBlue Swirl2012-08-091-5/+13
| | | | | | | | | | The qemu_irq for Terminal Count (TC) line between FDC and Slavio misc device was created only after use, spotted by Clang compiler. Also, it was not created if the FDC didn't exist. Rearrange code to fix order. Always create the TC line. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

* Rename cpu_reset() to cpu_state_reset()Andreas Färber2012-03-141-2/+2
| | | | | | | | | | Frees the identifier cpu_reset for QOM CPUs (manual rename). Don't hide the parameter type behind explicit casts, use static functions with strongly typed argument to indirect. Signed-off-by: Andreas Färber <afaerber@suse.de> Reviewed-by: Anthony Liguori <aliguori@us.ibm.com>
* qom: Unify type registrationAndreas Färber2012-02-151-28/+9
| | | | | | | | | | | | | Replace device_init() with generalized type_init(). While at it, unify naming convention: type_init([$prefix_]register_types) Also, type_init() is a function, so add preceding blank line where necessary and don't put a semicolon after the closing brace.

* qdev: register all types natively through QEMU Object ModelAnthony Liguori2012-02-031-22/+28
| | | | | | | | | | | | | | | | | | | | | This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* sysbus: apic: ioapic: convert to QEMU Object ModelAnthony Liguori2012-01-271-23/+55
| | | | | | | This converts three devices because apic and ioapic are subclasses of sysbus. Converting subclasses independently of their base class is prohibitively hard. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* vmstate, memory: decouple vmstate from memory APIAvi Kivity2012-01-041-4/+8
| | | | | | | | | | | | | | Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: Avi Kivity <avi@redhat.com>

* sparc32: ledma extra registersBob Breuer2010-12-181-7/+9
| | | | | | | | | | ledma has 0x20 bytes of registers according to OBP, and at least Solaris9 reads the 5th register which is beyond what we've mapped. So let's setup a flag (inspired by a previous patch from Blue Swirl) to identify ledma from espdma, and map another 16 bytes of registers which return 0.

* ESP: fix ESP DMA access when DMA is not enabledBlue Swirl2010-09-111-9/+14
| | | | | | | | | | | | | | Sending ESP a command caused it to trigger DMA immediately even if DMA was not enabled at the DMA controller. Add a signal from DMA controller to ESP to tell ESP about changes in DMA enable bit. Also use the correct function for setting up GPIO outputs. This fixes NetBSD 1.6.1 through 3.0 boot.

* Pad iommu with an empty slot (necessary for SunOS 4.1.4)Artyom Tarasenko2010-05-291-1/+13
| | | | | | | | | | On the real hardware (SS-5, LX) the MMU is not padded, but aliased. Software shouldn't use aliased addresses, neither should it crash when it uses (on the real hardware it wouldn't). Using empty_slot instead of aliasing can help with debugging such accesses.

* load_elf: replace the address addend by a translation functionAurelien Jarno2010-03-161-4/+15
| | | | | | | | | | | | | | | | A few machines need to translate the ELF header addresses into physical addresses. Currently the only possibility is to add a value to the addresses. This patch replaces the addend argument by and a translation function and an opaque passed to the function. A NULL function does not translate the address. The patch also convert all machines that have an addend, simplify the PowerPC kernel loading and fix the MIPS kernel loading using this new feature. Other machines may benefit from this feature.

* rom loader: fix sparc -kernel boot.Gerd Hoffmann2009-10-121-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | Changes: (1) register pstrcpy_targphys() in rom list, it is used for kernel command lines by a number of architectures. (2) add rom_ptr() function to get a pointer for applying changes to loaded images. Needed for example to tell the linux kernel where it finds the initrd image by updating the header. (3) make sparc use rom_ptr for initrd setup. booting sparc-test works now, and 'info roms' shows this: (qemu) info roms addr=0000000000000000 size=0x2a3828 mem=ram name="phdr #0: vmlinux-2.6.11+tcx" addr=00000000007ff000 size=0x00000e mem=ram name="cmdline" addr=0000000000800000 size=0x400000 mem=ram name="/root/qemu-test/sparc-test/linux.img" addr=0000000070000000 size=0x0e4000 mem=rom name="phdr #0: /home/kraxel/projects/qemu/build-zfull/pc-bios/openbios-sparc32" reboot via 'system_reset' works too.

* New qdev_init_nofail()Markus Armbruster2009-10-071-14/+14
| | | | | | | | | | | | | | | | | | | Like qdev_init(), but terminate program via hw_error() instead of returning an error value. Use it instead of qdev_init() where terminating the program on failure is okay, either because it's during machine construction, or because we know that failure can't happen. Because relying in the latter is somewhat unclean, and the former is not always obvious, it would be nice to go back to qdev_init() in the not-so-obvious cases, only with proper error handling. I'm leaving that for another day, because it involves making sure that error values are properly checked by all callers.

* qdev: add return value to init() callbacks.Gerd Hoffmann2009-08-271-3/+6
| | | | | | | | | | | | | | | | | | Sorry folks, but it has to be. One more of these invasive qdev patches. We have a serious design bug in the qdev interface: device init callbacks can't signal failure because the init() callback has no return value. This patch fixes it. We have already one case in-tree where this is needed: Try -device virtio-blk-pci (without drive= specified) and watch qemu segfault. This patch fixes it. With usb+scsi being converted to qdev we'll get more devices where the init callback can fail for various reasons.

* Sparc32: improve interrupt handlingBlue Swirl2009-08-251-5/+2
| | | | | | | | | | | | | | | | | Level 15 interrupts are broadcast to all CPUs, each CPU can clear the interrupt using the local Clear Pending register. Update intbit_to_level table. Don't try to raise level 0 interrupts. Calculate pending interrupts based on the separate inputs from master register. Setting or resetting the pending level isn't correct because of overlap of levels. Level 14 is always used for CPU timer interrupts, remove the property.
