2010-04-08update bochs vbe interfaceGerd Hoffmann2-3/+7
The bochs vbe interface got a new register a while back, which specifies the linear framebuffer size in 64k units. This patch adds support for the new register to qemu. With this patch applied vgabios 0.6c works with qemu. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-04-05Split TLB addend and target_phys_addr_tPaul Brook9-59/+32
Historically the qemu tlb "addend" field was used for both RAM and IO accesses, so needed to be able to hold both host addresses (unsigned long) and guest physical addresses (target_phys_addr_t). However since the introduction of the iotlb field it has only been used for RAM accesses. This means we can change the type of addend to unsigned long, and remove associated hacks in the big-endian TCG backends. We can also remove the host dependence from target_phys_addr_t.

2010-04-03Make cpu_get_real_ticks use mfsprAlexander Graf1-3/+3
PowerPC CPUs have had two ways to read the time base for quite some time now. They provide it using the mfspr instruction or - if a special bit is set in that opcode - using mftb. For timekeeping we're currently using mftb. While trying to get Qemu up and running on an e500v2 system, I stumbled over the CPU not supporting mftbu. It just throws an illegal instruction trap. So let's read the SPR values instead. All PPC CPUs should support them anyways. I tested this patch on an e500v2 system where it makes qemu work and on my 970MP system with 32-bit user space where everything still works with this patch applied.

2010-04-01tcg: initial ia64 supportAurelien Jarno4-15/+2488
A few words about design choices: * On IA64, instructions should be grouped by bundle, and dependencies between instructions declared. A first version of this code tried to schedule instructions automatically, but was very complex and too invasive for the current common TCG code (ops not ending at instruction boundaries, code retranslation breaking already generated code, etc.) It was also not very efficient, as dependencies between TCG ops is not available. Instead the option taken by the current implementation does not try to fill the bundle by scheduling instructions, but by providing ops not available as an ia64 instruction, and by offering 22-bit constant loading for most of the instructions. With both options the bundle are filled at approximately the same level. * Up to 128 registers can be affected to a function on IA64, but TCG limits this number to 64, which is actually more than enough. The register affectation is the following: - r0: used to map a constant argument with value 0 - r1: global pointer - r2, r3: internal use - r4 to r6: not used to avoid saving them - r7: env structure - r8 to r11: free for TCG (call clobbered) - r12: stack pointer - r13: thread pointer - r14 to r31: free for TCG (call clobbered) - r32: reserved (return address) - r33: reserved (PFS) - r33 to r63: free for TCG * The IA64 architecture has only 64-bit registers and no 32-bit instructions (the only exception being cmp4). Therefore 64-bit registers and instructions are used for 32-bit ops. The adopted strategy is the same as the ABI, that is the higher 32 bits are undefined. Most ops (and, or, add, shl, etc.) can directly use the 64-bit registers, while some others have to sign-extend (sar, div, etc.) or zero-extend (shr, divu, etc.) the register first.

2010-04-01linux-user/ia64: workaround ia64 strangenessesAurelien Jarno3-106/+114
ia64 has some strangenesses that need to be workaround: - it has a __clone2() syscall instead of the using clone() one, with different arguments, and which is not declared in the usual headers. - ucontext.uc_sigmask is declared with type long int, while it is actually of type sigset_t. - uc_mcontext, uc_sigmask, uc_stack, uc_link are declared using #define, which clashes with the target_ucontext fields. Change their names to tuc_*, as already done for some target architectures.
2010-04-01virtio-net: vhost net supportMichael S. Tsirkin1-2/+69
This connects virtio-net to vhost net backend. The code is structured in a way analogous to what we have with vnet header capability in tap.

2010-04-01virtio-pci: fill in notifier supportMichael S. Tsirkin1-0/+63
Support host/guest notifiers in virtio-pci. The last one only with kvm, that's okay because vhost relies on kvm anyway. Note on kvm usage: kvm ioeventfd API is implemented on non-kvm systems as well, this is the reason we don't need if (kvm_enabled()) around it. Signed-off-by: Michael S.

2010-04-01notifier: event notifier implementationMichael S. Tsirkin4-0/+80
event notifiers are slightly generalized eventfd descriptors. Current implementation depends on eventfd because vhost is the only user, and vhost depends on eventfd anyway, but a stub is provided for non-eventfd case. We'll be able to further generalize this when another user comes along and we see how to best do this. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01kvm: add API to set ioeventfdMichael S. Tsirkin2-1/+39
Comment on kvm usage: rather than require users to do if (kvm_enabled()) and/or ifdefs, this patch adds an API that, internally, is defined to stub function on non-kvm build, and checks kvm_enabled for non-kvm run. While rest of qemu code still uses if (kvm_enabled()), I think this approach is cleaner, and we should convert rest of code to it long term. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
