2013-07-01PPC: Fix GDB read on code area for PPC6xxFabien Chouteau
On PPC 6xx, data and code have separated TLBs. Until now QEMU was only looking at data TLBs, which is not good when GDB wants to read code. This patch adds a second call to get_physical_address() with an ACCESS_CODE type of access when the first call with ACCESS_INT fails.

2013-07-01booke_ppc: limit booke timer to max when timeout overflowBharat Bhushan
Limit watchdog and fit timer to maximum timeout value which qemu timer can support (INT64_MAX). This maximum timeout will be hundreds of years, so limiting to max timeout is pretty safe. Signed-off-by: Bharat Bhushan <bharat.bhushan@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-01Graphics: Switch to 800x600x32 as default modeAlexander Graf
We have stayed at 800x600x15 as default graphics mode for the last 9 years. If there ever was a reason to be there, surely nobody remembers it. However, recently non-Linux PPC guests started to show bad effects on 15 bit color mode. They do work just fine with 32 bits however. So let's switch to 32 bit color as the default graphic mode.

2013-07-01spapr-rtas: add CPU argument to RTAS callsAnthony Liguori
RTAS is a hypervisor provided binary blob that a guest loads and calls into to execute certain functions. It's similar to the vsyscall page in Linux or the short lived VMCI paravirt interface from VMware. The QEMU implementation of the RTAS blob is simply a passthrough that proxies all RTAS calls to the hypervisor via an hypercall. While we pass a CPU argument for hypercall handling in QEMU, we don't pass it for RTAS calls. Since some RTAs calls require making hypercalls (normally RTAS is implemented as guest code) we have nasty hacks to allow that. Add a CPU argument to RTAS call handling so we can more easily invoke hypercalls just as guest code would.

2013-07-01target-ppc: Change default machine for 64-bitDavid Gibson
Currently, for qemu-system-ppc64, the default machine type is 'mac99'. The mac99 machine is not being actively maintained, and represents a bizarre hybrid of components that never actually existed as a real system. This patch changes the default machine to 'pseries', which is actively maintained and works well with most modern ppc64 Linux distributions as a guest.

2013-07-01kvm/openpic: in-kernel mpic supportScott Wood
Enables support for the in-kernel MPIC that thas been merged into the KVM next branch. This includes irqfd/KVM_IRQ_LINE support from Alex Graf (along with some other improvements). Note from Alex regarding kvm_irqchip_create(): On x86, one would call kvm_irqchip_create() to initialize an in-kernel interrupt controller. That function then goes ahead and initializes global capability variables as well as the default irq routing table. On ppc, we can't call kvm_irqchip_create() because we can have different types of interrupt controllers. So we want to do all the things that function would do for us in the in-kernel device init handler.

2013-07-01PPC: Add non-kvm stub fileAlexander Graf

2013-07-01KVM: PIC: Only commit irq routing when necessaryAlexander Graf
The current logic updates KVM's view of our interrupt map every time we change it. While this is nice and bullet proof, it slows things down badly for me. QEMU spends about 3 seconds on every start telling KVM what news it has on its routing maps. Instead, let's just synchronize the whole irq routing map as a whole when we're done constructing it. For things that change during runtime, we can still update the routing table on demand. Signed-off-by: Alexander Graf <agraf@suse.de>

2013-07-01KVM: MSI: Swap payload to native endiannessAlexander Graf
The usual MSI injection mechanism writes msi.data into memory using an le32 wrapper. So on big endian guests, this swaps msg.data into the expected byte order. For irqfd however, we don't swap the payload right now, rendering in-kernel MPIC emulation broken on PowerPC. Swap msg.data to the correct endianness whenever we touch it. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-01KVM: Export kvm_init_irq_routingAlexander Graf
On PPC, we can have different types of interrupt controllers, so we really only know that we are going to use one when we created it. Export kvm_init_irq_routing() to common code, so that we don't have to call kvm_irqchip_create(). Signed-off-by: Alexander Graf <agraf@suse.de>
2013-07-01KVM: Don't assume that mpstate exists with in-kernel PIC alwaysAlexander Graf
On PPC, we don't support MP state. So far it's not necessary and I'm not convinced yet that we really need to support it ever. However, the current idle logic in QEMU assumes that an in-kernel PIC also means we support MP state. This assumption is not true anymore. Let's split up the two cases into two different variables. That way PPC can expose an in-kernel PIC, while not implementing MP state. Signed-off-by: Alexander Graf <agraf@suse.de> CC: Jan Kiszka <jan.kiszka@siemens.com>

2013-06-28qemu-char: Fix ID reuse after chardev-remove for qapi-based initMarkus Armbruster
Commit 2c5f488 introduced qapi-based character device initialization as a new code path in qemu_chr_new_from_opts(). Unfortunately, it failed to store parameter opts in the new chardev. Therefore, qemu_chr_delete() doesn't delete it. Even though the device is gone, its options linger, and any attempt to create another one with the same ID fails.

2013-06-28vl: convert -smp to qemu_opts_parse()Michael Tokarev
This also introduces a new suboption, "cpus=", which is the default. So after this patch, -smp n,sockets=y is the same as -smp cpus=n,sockets=y (with "cpu" being some generic thing, referring to either cores, or threads, or sockets, as before). We still don't validate relations between different numbers, for example it is still possible to say -smp 1,sockets=10 and it will be accepted to mean sockets=1.

2013-06-28multiboot: Calculate upper_mem in the ROMKevin Wolf
The upper_mem field of the Multiboot information struct doesn't really contain the RAM size - 1 MB like we used to calculate it, but only the memory from 1 MB up to the first (upper) memory hole. In order to correctly retrieve this information, the multiboot ROM now looks at the mmap it creates anyway and tries to find the size of contiguous usable memory from 1 MB. Drop the multiboot.c definition of lower_mem and upper_mem because both are queried at runtime now.

2013-06-28multiboot: Don't forget last mmap entryKevin Wolf
When the BIOS returns ebx = 0, the current entry is still valid and needs to be included in the Multiboot memory map. Fixing this meant that using bx as the entry index doesn't work any more because it's 0 on the last entry (and it was SeaBIOS-specific anyway), so the whole loop had to change a bit and should be more generic as a result (ebx can be an arbitrary continuation number now, and the entry size returned by the BIOS is used instead of hard-coding 20 bytes).

length is a ram_addr_t, so RAM_ADDR_FMT must be used instead of %ld. This fixes a recently introduced regression for w64 builds. Using RAM_ADDR_FMT also changes decimal output to sedecimal.
