2015-09-10xen: use errno instead of rc for xc_domain_add_to_physmapKonrad Rzeszutek Wilk
In Xen 4.6 commit cd2f100f0f61b3f333d52d1737dd73f02daee592 "libxc: Fix do_memory_op to return negative value on errors" made the libxc API less odd-ball: On errors, return value is -1 and error code is in errno. On success the return value is either 0 or an positive value. Since we could be running with an old toolstack in which the Exx value is in rc or the newer, we add an wrapper around the xc_domain_add_to_physmap (called xen_xc_domain_add_to_physmap) which will always return the EXX. Xen 4.6 did not change the libxc functions mentioned (same parameters) so we piggyback on the fact that Xen 4.6 has a new function: commit 504ed2053362381ac01b98db9313454488b7db40 "tools/libxc: Expose new hypercall xc_reserved_device_memory_map" and check for that.

2015-09-10xen/HVM: atomically access pointers in bufioreq handlingJan Beulich
The number of slots per page being 511 (i.e. not a power of two) means that the (32-bit) read and write indexes going beyond 2^32 will likely disturb operation. The hypervisor side gets I/O req server creation extended so we can indicate that we're using suitable atomic accesses where needed, allowing it to atomically canonicalize both pointers when both have gone through at least one cycle. The Xen side counterpart (which is not a functional prereq to this change, albeit a build one) went in already (commit b7007bc6f9).

2015-09-10igd gfx passthrough: create a isa bridgeTiejun Chen
Currently IGD drivers always need to access PCH by 1f.0. But we don't want to poke that directly to get ID, and although in real world different GPU should have different PCH. But actually the different PCH DIDs likely map to different PCH SKUs. We do the same thing for the GPU. For PCH, the different SKUs are going to be all the same silicon design and implementation, just different features turn on and off with fuses. The SW interfaces should be consistent across all SKUs in a given family (eg LPT). But just same features may not be supported. Most of these different PCH features probably don't matter to the Gfx driver, but obviously any difference in display port connections will so it should be fine with any PCH in case of passthrough. So currently use one PCH version, 0x8c4e, to cover all HSW(Haswell) scenarios, 0x9cc3 for BDW(Broadwell).

2015-09-10error: On abort, report where the error was createdMarkus Armbruster
This is particularly useful when we abort in error_propagate(), because there the stack backtrace doesn't lead to where the error was created. Looks like this: Unexpected error in parse_block_error_action() at .../qemu/blockdev.c:322: qemu-system-x86_64: -drive if=none,werror=foo: 'foo' invalid write error action Aborted (core dumped) Note: to get this example output, I monkey-patched drive_new() to pass &error_abort to blockdev_init(). To keep the error handling boiler plate from growing even more, all error_setFOO() become macros expanding into error_setFOO_internal() with additional __FILE__, __LINE__, __func__ arguments. Not exactly pretty, but it works. The macro trickery breaks down when you take the address of an error_setFOO(). Fortunately, we do that in just one place: qemu-ga's Windows VSS provider and requester DLL wants to call error_setg_win32() through a function pointer "to avoid linking glib to the DLL". Use error_setg_win32_internal() there. The use of the function pointer is already wrapped in a macro, so the churn isn't bad. Code size increases by some 35KiB for me (0.7%). Tolerable. Could be less if we passed relative rather than absolute source file names to the compiler, or forwent reporting __func__.

2015-09-10qga: Clean up unnecessarily dirty castsMarkus Armbruster
qga_vss_fsfreeze() casts error_set_win32() from void (*)(Error **, int, ErrorClass, const char *, ...) to void (*)(void **, int, int, const char *, ...) The result is later called. Since the two types are not compatible, the call is undefined behavior. It works in practice anyway. However, there's no real need for trickery here. Clean it up as follows: * Declare struct Error, and fix the first parameter. * Switch to error_setg_win32(). This gets rid of the troublesome ErrorClass parameter. Requires converting error_setg_win32() from macro to function, but that's trivially easy, because this is the only user of error_set_win32().

2015-09-08hw/intc/arm_gic_common: Configure IRQs as NS if doing direct NS kernel bootPeter Maydell
If we directly boot a kernel in NonSecure on a system where the GIC supports the security extensions then we must cause the GIC to configure its interrupts into group 1 (NonSecure) rather than the usual group 0, and with their initial priority set to the highest NonSecure priority rather than the usual highest Secure priority. Otherwise the guest kernel will be unable to use any interrupts. Implement this behaviour, controlled by a flag which we set if appropriate when the ARM bootloader code calls our ARMLinuxBootIf interface callback.

2015-09-08hw/arm: new interface for devices which need to behave differently for ↵Peter Maydell
kernel boot For ARM we have a little minimalist bootloader in hw/arm/boot.c which takes the place of firmware if we're directly booting a Linux kernel. Unfortunately a few devices need special case handling in this situation to do the initialization which on real hardware would be done by firmware. (In particular if we're booting a kernel in NonSecure state then we need to make a TZ-aware GIC put all its interrupts into Group 1, or the guest will be unable to use them.) Create a new QOM interface which can be implemented by devices which need to do something different from their default reset behaviour. The callback will be called after machine initialization and before first reset.

2015-09-08hw/intc/arm_gic: Drop running_irq and last_active arraysPeter Maydell
The running_irq and last_active arrays represent state which doesn't exist in a real hardware GIC. The only thing we use them for is updating the running priority when an interrupt is completed, but in fact we can use the active-priority registers to do this. The running priority is always the priority corresponding to the lowest set bit in the active priority registers, because only one interrupt at any particular priority can be active at once.

2015-09-07s390/sclp: rework sclp event facility initialization + device realizationDavid Hildenbrand
The current code only works by chance. The event facility is a sysbus device, but specifies in its class structure as parent the DeviceClass (instead of a device class). The init function in return lies therefore at the same position as the init function of SysBusDeviceClass and gets triggered instead - a very bad idea of doing that (e.g. the parameter types don't match). Let's bring the initialization code up to date, initializing the event facility + child events in .instance_init and moving the realization of the child events out of the init call, into the realization step. Device realization is now automatically performed when the event facility itself is realized. That realization implicitly triggers realization of the child bus, which in turn initializes the events. Please note that we have to manually propagate the realization of the bus children, common code still has a TODO set for that task.

2015-09-07hw/arm/virt: Add high MMIO PCI region, 512G in sizePavel Fedin
This large region is necessary for some devices like ivshmem and video cards 32-bit kernels can be built without LPAE support. In this case such a kernel will not be able to use PCI controller which has windows in high addresses. In order to work around the problem, "highmem" option is introduced. It defaults to on on, but can be manually set to off in order to be able to run those old 32-bit guests.
