2010-03-16load_elf: replace the address addend by a translation functionAurelien Jarno1-4/+10
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.

2010-01-27sparc64: reimplement tick timers v4Igor V. Kovalenko1-33/+173
sparc64 timer has tick counter which can be set and read, and tick compare value used as deadline to fire timer interrupt. The timer is not used as periodic timer, instead deadline is set each time new timer interrupt is needed. v3 -> v4: - coding style v2 -> v3: - added missing timer debug output macro - CPUTimer struct and typedef moved to cpu.h - change CPU_SAVE_VERSION to 6, older save formats not supported v1 -> v2: - new conversion helpers cpu_to_timer_ticks and timer_to_cpu_ticks - save offset from clock source to implement cpu_tick_set_count - renamed struct sun4u_timer to CPUTimer - load and save cpu timers v0 -> v1: - coding style Signed-off-by: Igor V.

2009-10-12rom loader: fix sparc -kernel boot.Gerd Hoffmann1-1/+1
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.

2009-10-07New qdev_init_nofail()Markus Armbruster1-2/+2
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.

2009-10-05Fix pci_add nic not to exit on bad modelMarkus Armbruster1-1/+1
Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to create the NIC. When MODEL is unknown or "?", this prints to stderr and terminates the program. Change pci_nic_init() not to treat "?" specially, and to return NULL on failure. Switch uses during startup to new convenience wrapper pci_nic_init_nofail(), which behaves just like pci_nic_init() used to do. Bonus bug fix: we now check for qdev_init() failing there.

That are all serial_init() users except mips_mipssim() which seems to have a non-standard IRQ windup. baud rate is fixed at 115200 now as no caller passed in something else.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-12/+12
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-09-20Compile loader only onceBlue Swirl1-3/+15
Callers must pass ELF machine, byte swapping and symbol LSB clearing information to ELF loader. A.out loader needs page size information, pass that too as a parameter. Extract prototypes to a separate file. Move loader.[ch] and elf_ops.h under hw. Adjust callers. Also use target_phys_addr_t instead of target_ulong for addresses: loader addresses aren't virtual.

2009-09-10qdev: simplify isa irq assignmentsGerd Hoffmann1-1/+1
isa-bus owns the isa irqs now, so it can hand them out directly. There is no need for the separate isa_connect_irqs step, drop it. Also hard-code isa interrupts which can't be configured anyway. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-09-10qdev: drop iobase properties from isa busGerd Hoffmann1-2/+2
Lot of ISA devices work at fixed addresses, so having iobase as bus property doesn't make much sense. Devices which can have different iobases will get a device property. Also simply hard-code stuff which can't be configured anyway. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2009-08-27qdev: add return value to init() callbacks.Gerd Hoffmann1-3/+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.

2009-08-27isa bus irq changes and fixes.Gerd Hoffmann1-1/+1
Changes: (1) make isa-bus maintain isa irqs, complain when allocating already taken irqs. (2) note that (1) works only for isa devices converted to qdev already (floppy and ps2/kbd/mouse right now), so more work is needed to make this really useful. (3) split floppy init into isa and sysbus versions. (4) add sysbus->isa bridge & fix -M isapc breakage.

First step cleaning up the drives handling. This one does nothing but removing drives_table[], still it became seriously big. drive_get_index() is gone and is replaced by drives_get() which hands out DriveInfo pointers instead of a table index.
