2011-10-30ppc: Avoid decrementer related kvm exitsDavid Gibson
In __cpu_ppc_store_decr(), we set up a regular timer used to trigger decrementer interrupts. This is necessary to implement the decrementer properly under TCG, but is unnecessary under KVM (true for both Book3S-PR and Book3S-HV KVM variants), because the kernel handles generating and delivering decrementer exceptions. Under kvm, in fact, the timer causes expensive and unnecessary exits from kvm to qemu. This patch, therefore, disables setting the timer when kvm is in use.

2011-10-06PPC: booke timersFabien Chouteau
While working on the emulation of the freescale p2010 (e500v2) I realized that there's no implementation of booke's timers features. Currently mpc8544 uses ppc_emb (ppc_emb_timers_init) which is close but not exactly like booke (for example booke uses different SPR).

2011-04-01Add POWER7 support for ppcDavid Gibson
This adds emulation support for the recent POWER7 cpu to qemu. It's far from perfect - it's missing a number of POWER7 features so far, including any support for VSX or decimal floating point instructions. However, it's close enough to boot a kernel with the POWER7 PVR. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-03-21change all other clock references to use nanosecond resolution accessorsPaolo Bonzini
This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.

2010-09-05KVM: PPC: Add level based interrupt logicAlexander Graf
KVM on PowerPC used to have completely broken interrupt logic. Usually, interrupts work by having a PIC that pulls a line up/down, so the CPU knows that an interrupt is active. This line stays active until some action is done to the PIC to release the line. On KVM for PPC, we just checked if there was an interrupt pending and pulled a line in the kernel module. We never released it though, hoping that kernel space would just declare an interrupt as released when injected - which is wrong. To fix this, we need to completely redesign the interrupt injection logic. Whenever an interrupt line gets triggered, we need to notify kernel space that the line is up. Whenever it gets released, we do the same. This way we can assure that the interrupt state is always known to kernel space. This fixes random stalls in KVM guests on PowerPC that were waiting for an interrupt while everyone else thought they received it already. Signed-off-by: Alexander Graf <agraf@suse.de>

2009-12-21PPC: Make DCR uint32_tAlexander Graf

2009-12-21PPC64: Fix timebaseAlexander Graf
On PPC we have a 64-bit time base. Usually (PPC32) this is accessed using two separate 32 bit SPR accesses to SPR_TBU and SPR_TBL. On PPC64 the SPR_TBL register acts as 64 bit though, so we get the full 64 bits as return value. If we only take the lower ones, fine. But Linux wants to see all 64 bits or it breaks. This patch makes PPC64 Linux work even after TB crossed the 32-bit boundary, which usually happened a few seconds after bootup.

2009-10-12rom loader: fix sparc -kernel boot.Gerd Hoffmann
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.
