2009-06-23target-ppc: permit linux-user to read PVRNathan Froyd1-1/+7
Access to the PVR SPR is normally forbidden from userspace apps. The Linux kernel, however, fixes up reads in the appropriate trap handler. To permit applications that read PVR to run on QEMU, then, we need to implement the same handling of PVR reads.

2009-05-22kvm: Add missing bits to support live migrationJan Kiszka1-0/+5
This patch adds the missing hooks to allow live migration in KVM mode. It adds proper synchronization before/after saving/restoring the VCPU states (note: PPC is untested), hooks into cpu_physical_memory_set_dirty_tracking() to enable dirty memory logging at KVM level, and synchronizes that drity log into QEMU's view before running ram_live_save().

2009-05-19Hardware convenience libraryPaul Brook1-1/+0
The only target dependency for most hardware is sizeof(target_phys_addr_t). Build these files into a convenience library, and use that instead of building for every target. Remove and poison various target specific macros to avoid bogus target dependencies creeping back in. Big/Little endian is not handled because devices should not know or care about this to start with. Signed-off-by: Paul Brook <paul@codesourcery.com>

2009-03-13Make the ELF loader aware of backwards compatibilityblueswir11-2/+1
Most 64 bit architectures I'm aware of support running 32 bit code of the same architecture as well. So x86_64 can run i386 code easily and ppc64 can run ppc code. Unfortunately, the current checks are pretty strict. So you can only load e.g. an x86_64 elf binary on qemu-system-x86_64, but no i386 one. This can get really annoying. I first encountered this issue with my multiboot patch, where qemu-system-x86_64 was unable to load an i386 elf binary because the elf loader rejected it. The same thing happened again on PPC64 now. The firmware we're loading is a PPC32 elf binary, as it's shared with PPC32. But the platform is PPC64. Right now there is a hack for this in the ppc cpu.h definition, that simply sets the type to PPC32 in system emulation mode. While that works fine for the firmware, it's no good if you also want to load a PPC64 kernel with -kernel. So in order to solve this mess, I figured the easiest way is to make the elf loader aware of platforms that are backwards compatible. For now I was only sure that x86_64 does i386 and ppc64 does ppc32, but maybe there are other combinations too. This patch is a prerequisite for having a working -kernel option on PPC64.

Altivec and SPE both have 34 registers in their register sets, not 35 with a missing register 32. GDB would ask for register 32 of the Altivec (resp. SPE) registers and the code would claim it had zero width. The QEMU GDB stub code would then return an E14 to GDB, which would complain about not being sure whether p packets were supported or not.

2009-03-07Keep SLB in-CPUblueswir13-64/+77
Real 970 CPUs have the SLB not memory backed, but inside the CPU. This breaks bridge mode for 970 for now, but at least keeps us from overwriting physical addresses 0x0 - 0x300, rendering our interrupt handlers useless. I put in a stub for bridge mode operation that could be enabled easily, but for now it's safer to leave that off I guess (970fx doesn't have bridge mode AFAIK).

2009-02-28Implement HIORblueswir11-8/+21
A real 970 CPU starts up with HIOR=0xfff00000 and triggers a reset exception, basically ending up at IP 0xfff001000. Later on this HIOR has to be set to 0 by the firmware in order to enable the OS to handle interrupts on its own. This patch maps HIOR to exec_prefix, which does the same thing internally in qemu already. It replaces the previous patch that changed the 970 initialization constants, as this is the clean solution to the same problem.
