The only user of ISADevice.ioports is isabus_get_fw_dev_path, and it only looks at the first entry of the array. Which suggests that this entire array+sort operation can be replaced by a simple minimum. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>

2011-10-08target-alpha: Add high-resolution access to wall clock and an alarm.Richard Henderson5-5/+68
The alarm is a fully general one-shot time comparator, which will be usable under Linux as a hrtimer source. It's much more flexible than the RTC source available on real hardware. The wall clock allows the guest access to the host timekeeping. Much like the KVM wall clock source for other guests. Both are accessed via the PALcode Cserve entry point.

2011-10-06pseries: Implement set-time-of-day RTAS functionBreno Leitao2-1/+24
Currently there is no implementation for set-time-of-day rtas function, which causes the following warning "setting the clock failed (-1)" on the guest. This patch just creates this function, get the timedate diff and store in the papr environment, so that the correct value will be returned by get-time-of-day. In order to try it, just adjust the hardware time, run hwclock --systohc, so that, on when the system runs hwclock --hctosys, the value is correctly adjusted, i.e. the host time plus the timediff.

2011-10-06pseries: Refactor spapr irq allocationDavid Gibson4-11/+31
Paulo Bonzini changed the original spapr code, which manually assigned irq numbers for each virtual device, to allocate them automatically from the device initialization. That allowed spapr virtual devices to be constructed with -device, which is a good start. However, the way that patch worked doesn't extend nicely for the future when we want to support devices other than sPAPR VIO devices (e.g. virtio and PCI). This patch rearranges the irq allocation to be global across the sPAPR environment, so it can be used by other bus types as well.

2011-10-06PPC: booke timersFabien Chouteau9-101/+427
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).

2011-10-06KVM: PPC: Use HIOR setting for -M pseries with PR KVMAlexander Graf1-3/+22
When running with PR KVM, we need to set HIOR directly. Thankfully there is now a new interface to set registers individually so we can just use that and poke HIOR into the guest vcpu's HIOR register. While at it, this also sets SDR1 because -M pseries requires it to run. With this patch, -M pseries works properly with PR KVM. Signed-off-by: Alexander Graf <agraf@suse.de>

2011-10-06openpic: Unfold write_IRQregAlexander Graf1-42/+37

The RAM_ADDR_FMT macro hides the type of ram_addr_t so that format strings can be safely used. Make sure to use RAM_ADDR_FMT so that the build works on 32-bit hosts with Xen enabled.

2011-10-06vscsi: send the CHECK_CONDITION status down together with autosense dataPaolo Bonzini1-1/+0
I introduced this bug in commit 05751d3 (vscsi: always use get_sense, 2011-08-03) because at the time there was no way to expose a sense condition to SLOF and Linux manages to work around the bug. However, the bug becomes evident now that SCSI devices also report unit attention on reset. SLOF also has problems dealing with unit attention conditions, so it still will not boot even with this fix (just like OpenBIOS). IBM folks are aware of their part of the bug. :-) Reported-by: Thomas Huth <thuth@linux.vnet.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Acked-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-10-06pseries: Implement hcall-bulk hypervisor interfaceDavid Gibson2-13/+114
This patch adds support for the H_REMOVE_BULK hypercall on the pseries machine. Strictly speaking this isn't necessarym since the kernel will only attempt to use this if hcall-bulk is advertised in the device tree, which previously it was not. Adding this support may give a marginal performance increase, but more importantly it reduces the differences between the emulated machine and an existing PowerVM or kvm system, both of which already implement hcall-bulk.

2011-10-06Implement POWER7's CFAR in TCGDavid Gibson3-1/+58
This patch implements support for the CFAR SPR on POWER7 (Come From Address Register), which snapshots the PC value at the time of a branch or an rfid. The latest powerpc-next kernel also catches it and can show it in xmon or in the signal frames. This works well enough to let recent kernels boot (which otherwise oops on the CFAR access). It hasn't been tested enough to be confident that the CFAR values are actually accurate, but one thing at a time.
