2011-05-15target-arm: Fix VMLA, VMLS, VNMLS, VNMLA handling of NaNsPeter Maydell1-13/+40
Correct handling of NaNs for VFP VMLA, VMLS, VNMLS and VNMLA requires that we implement the set of negations and additions specified by the ARM ARM; plausible looking simplifications like turning (-A + B) into (B - A) or computing (A + B) rather than (B + A) result in selecting the wrong NaN or returning a NaN with the wrong sign bit.

2011-05-15doc: Add explanation that -alt-grab and -ctrl-grab affect special keysBrad Hards2-3/+9
Phillip Merensky reported that the special keys (e.g. Ctrl-Alt-f for full screen) did not work correctly if -alt-grab is used. BUG: 696530 Review of ui/sdl.c:sdl_refresh indicates that this is the intended behaviour, so we should update the documentation to match the actual behaviour, as suggested by Phillip in the bug report.

2011-05-12PPC: Qdev'ify e500 pciAlexander Graf3-90/+84
The e500 PCI controller isn't qdev'ified yet. This leads to severe issues when running with -drive. To be able to use a virtio disk with an e500 VM, let's convert the PCI controller over to qdev. Reviewed-by: Paul Brook <paul@codesourcery.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-12PPC MPC7544DS: Use new TLB helper functionAlexander Graf1-1/+1
Now that we have some nice helpers that can find us a TLB entry, let's use that on the machine initialization code, so we don't need to know about the internals of the TLB array. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-12PPC: Implement e500 (FSL) MMUAlexander Graf6-113/+1020
Most of the code to support e500 style MMUs is already in place, but we're missing on some of the special TLB0-TLB1 handling code and slightly different TLB modification. This patch adds support for the FSL style MMU. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-12PPC: Add another 64 bits to instruction feature maskAlexander Graf3-39/+110
To enable quick runtime detection of instruction groups to the currently selected CPU emulation, we have a feature mask of what exactly the respective instruction supports. This feature mask is 64 bits long and we just successfully exceeded those 64 bits. To add more features, we need to think of something. The easiest solution that came to my mind was to simply add another 64 bits that we can also match on. Since the comparison is only done on start of the qemu process to generate an internal opcode calling table, we should be fine on any performance penalties here.

2011-05-12PPC: Add GS MSR definitionAlexander Graf1-0/+2
The BookE specification defines MSR bit 28 as Guest State. Add it to the list of MSR macros. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-12PPC: Make MPC8544DS emulation work w/o KVMAlexander Graf1-17/+74
The MPC8544DS board emulation was only used with KVM so far, so some parts of the code didn't provide proper values for non-KVM execution. This patch makes the machine work without KVM enabled. To actually use this, you also need proper e500v2 MMU emulation. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-12PPC: Make MPC8544DS obey -cpu switchAlexander Graf1-1/+5
The MPC8544DS board emulation code ignored the user defined -cpu switch. This patch enables it to only provide a sane default, not force an e500v2 CPU inside. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-10Fix off-by-one error in sizing pSeries hcall tableDavid Gibson1-2/+2
The pSeries machine uses two tables to look up guest hcalls for emulation. One of these is exactly one entry too small to hold all the hcalls it needs to, leading to memory corruption. This patch fixes the bug, and while we're at it, make both tables 'static' since they're never used from other modules.

2011-05-09kvm: ppc: warn user on PAGE_SIZE mismatchAlexander Graf1-0/+5
On PPC, the default PAGE_SIZE is 64kb. Unfortunately, the hardware alignments don't match here: There are RAM and MMIO regions within a single page when it's 64kb in size. So the only way out for now is to tell the user that he should use 4k PAGE_SIZE. This patch gives the user a hint on that, telling him that failing to register a prefix slot is most likely to be caused by mismatching PAGE_SIZE. This way it's also more future-proof, as bigger PAGE_SIZE can easily be supported by other machines then, as long as they stick to 64kb granularities. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-09kvm: ppc: detect old headersAlexander Graf2-1/+33
When compiling Qemu with older kernel headers, the PVR setting mechanism isn't available yet. Unfortunately, back then I didn't add a capability we could check against, so all we can do is add a configure test to see if we support PVR setting. For BookE, we don't care yet. This fixes compilation errors with KVM enabled on older kernel headers (like 2.6.32). Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-09monitor: add PPC BookE SPRsScott Wood5-13/+296
Read them via KVM_GET_SREGS in kvm_arch_get_registers(), and display them in "info registers". Also get CR and PID from the existing KVM_GET_REGS. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2011-05-09kvm: ppc: fixes for KVM_SET_SREGS on initScott Wood1-3/+30
Classic/server ppc has had SREGS for a while now (though I think not always?), but it's still missing for booke. Check the capability before calling KVM_SET_SREGS. Without this, booke kvm fails to boot as of commit 84b4915dd2c0eaa86c970ffc42a68ea8ba9e48b5 (kvm: Handle kvm_init_vcpu errors). Also, don't write random stack state into the non-PVR sregs fields -- have kvm fill it in first. Eventually booke will have sregs and it will have its own capability to be tested here. However, we will want a way for platform code to request to look like the actual CPU we're running on, especially if SoC devices are being directly assigned.

2011-05-09Place pseries vty devices at addresses more similar to existing machinesDavid Gibson3-3/+7
Currently the qemu pseries machine numbers its virtual serial devices from 0. However, existing pSeries machines running pHyp number them from 0x30000000. In theory these indices are arbitrary, since everything necessary for the kernel to find them is advertised in the device tree. However the debian installer, at least, incorrectly looks for a device named vty@30... to determine whether to use the hypervisor console. Therefore this patch moves the numbers we use to match the existing pHyp practice, in order to workaround broken userspace apps of this type.

2011-05-09Make pSeries 'model' property more closely resemble real hardwareDavid Gibson1-1/+1
Currently, the qemu emulated pseries machine puts "qemu,emulated-pSeries-LPAR" in the device tree's root level 'model' property. Unfortunately this confuses some installers and ybin, which expect this to start with "IBM" on pSeries machines. This patch addresses this problem, making the property more closely resemble the pattern of existing real hardware.

2011-05-09pseries: Increase maximum CPUs to 256Anton Blanchard1-1/+1
The original pSeries machine was limited to 32 CPUs, more or less arbitrarily. Particularly when we get SMT KVM guests it will be pretty easy to exceed this. Therefore, raise the max number of CPUs in a pseries machine guest to 256.

Prototype without "inline" keyword breaks the build with some gcc versions. Noticed by Alexander Graf. Fix this by removing the inline keywork everywhere. Some functions can't be inlined anyway as the are referenced using function pointers. Beside that gcc does a pretty good job on auto-inlining these days.

These defines will be place-holders for cpu-specific functionality. Generic code will, at the end of the patch series, no longer have to concern itself about how SMI, NMI, etc should be handled.
