2016-05-12tcg: Remove needless CPUState::current_tbSergey Fedorov1-1/+0
This field was used for telling cpu_interrupt() to unlink a chain of TBs being executed when it worked that way. Now, cpu_interrupt() don't do this anymore. So we don't need this field anymore.

2016-05-12tb: consistently use uint32_t for tb->flagsEmilio G. Cota1-1/+1
We are inconsistent with the type of tb->flags: usage varies loosely between int and uint64_t. Settle to uint32_t everywhere, which is superior to both: at least one target (aarch64) uses the most significant bit in the u32, and uint64_t is wasteful. Compile-tested for all targets.

2016-04-13tpm: acpi: remove IRQ from TPM's CRS to make Windows not see conflictIgor Mammedov1-1/+6
IRQ 5 used by TPM conflicts with PNP0C0F IRQs, as result Windows fails driver initialization with reason 'device cannot find enough free resources' But if TPM._CRS.IRQ entry is commented out, Windows seems to initialize driver without errors as it doesn't notice possible conflict and it seems to work probably due to a link with IRQ 5 being unused/disabled. So temporary comment out TPM._CRS.IRQ to 'fix' regression in TPM, with intent to fix it correctly later i.e.: 1. pick unused IRQ as default one for TPM 2. fetch IRQ value from device model so that user could override default one if it conflicts with some other device.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little.

2016-03-11machine: introduce MachineClass.possible_cpu_arch_ids() hookIgor Mammedov1-4/+40
on x86 currently range 0..max_cpus is used to generate architecture-dependent CPU ID (APIC Id) for each present and possible CPUs. However architecture-dependent CPU IDs list could be sparse and code that needs to enumerate all IDs (ACPI) ended up doing guess work enumerating all possible and impossible IDs up to apic_id_limit = x86_cpu_apic_id_from_index(max_cpus). That leads to creation of MADT entries and Processor objects in ACPI tables for not possible CPUs. Fix it by allowing board specify a concrete list of CPU IDs accourding its own rules (which for x86 depends on topology). So that code that needs this list could request it from board instead of trying to guess what IDs are correct on its own. This interface will also allow to help making AML part of CPU hotplug target independent so it could be reused for ARM target.

2016-03-11i386: populate floppy drive information in DSDTRoman Kagan1-3/+66
On x86-based systems Linux determines the presence and the type of floppy drives via a query of a CMOS field. So does SeaBIOS when populating the return data for int 0x13 function 0x08. However Windows doesn't do it. Instead, it requests this information from BIOS via int 0x13/0x08 or through ACPI objects _FDE (Floppy Drive Enumerate) and _FDI (Floppy Drive Information) of the floppy controller object. On UEFI systems only ACPI-based detection is supported. QEMU doesn't provide those objects in its ACPI tables and as a result floppy drives are invisible to Windows on UEFI/OVMF. This patch adds those objects to the floppy controller in DSDT, populating them with the information from respective QEMU objects.

2016-03-04loader: Add data swap option to load-elfPeter Crosthwaite1-1/+2
Some CPUs are of an opposite data-endianness to other components in the system. Sometimes elfs have the data sections layed out with this CPU data-endianness accounting for when loaded via the CPU, so byte swaps (relative to other system components) will occur. The leading example, is ARM's BE32 mode, which is is basically LE with address manipulation on half-word and byte accesses to access the hw/byte reversed address. This means that word data is invariant across LE and BE32. This also means that instructions are still LE. The expectation is that the elf will be loaded via the CPU in this endianness scheme, which means the data in the elf is reversed at compile time. As QEMU loads via the system memory directly, rather than the CPU, we need a mechanism to reverse elf data endianness to implement this possibility.

2016-02-10xen: drop support for Xen 4.1 and older.Ian Campbell1-4/+0
Xen 4.2 become unsupported upstream in 09/2015 (see http://wiki.xen.org/wiki/Xen_Release_Features). However as far as the interfaces provided by the toolstack libraries go 4.2 and 4.3 are indistinguishable. Therefore drop support for Xen 4.1 and earlier which removes a whole pile of compatibility code which makes future work (to use stable library interfaces provided by upstream) more difficult. In particular all supported versions now use a pointer as a libxc handle (4.1 and earlier used an integer, resulting in various shim layers). Also Xen 4.2 was the first version of Xen to formally support upstream QEMU (as a preview) so that makes sense as a cut-off now. This change drops all the configure-y and resulting ifdefs in a mostly mechanical way. A follow up will refactor wrappers which are now unused.

It's time to do a global swap of the parameter ordering, so that the 'name' parameter is always immediately after the Visitor argument. Additional reason in favor of the swap: the existing include/qjson.h prefers listing 'name' first in json_prop_*(), and I have plans to unify that file with the qapi visitors; listing 'name' first in qapi will minimize churn to the (admittedly few) qjson.h clients. Later patches will then fix docs, object.h, visitor-impl.h, and those clients to match. Done by first patching scripts/qapi*.py by hand to make generated files do what I want, then by running the following Coccinelle script to affect the rest of the code base: $ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'` I then had to apply some touchups (Coccinelle insisted on TAB indentation in visitor.h, and botched the signature of visit_type_enum() by rewriting 'const char *const strings[]' to the syntactically invalid 'const char*const[] strings'). The movement of parameters is sufficient to provoke compiler errors if any callers were missed. // Part 1: Swap declaration order @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_start_struct -(TV v, TObj OBJ, T1 ARG1, const char *name, T2 ARG2, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type bool, TV, T1; identifier ARG1; @@ bool visit_optional -(TV v, T1 ARG1, const char *name) +(TV v, const char *name, T1 ARG1) { ... } @@ type TV, TErr, TObj, T1; identifier OBJ, ARG1; @@ void visit_get_next_type -(TV v, TObj OBJ, T1 ARG1, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, TErr errp) { ... } @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_type_enum -(TV v, TObj OBJ, T1 ARG1, T2 ARG2, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type TV, TErr, TObj; identifier OBJ; identifier VISIT_TYPE =~ "^visit_type_"; @@ void VISIT_TYPE -(TV v, TObj OBJ, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, TErr errp) { ... } // Part 2: swap caller order @@ expression V, NAME, OBJ, ARG1, ARG2, ERR; identifier VISIT_TYPE =~ "^visit_type_"; @@ ( -visit_start_struct(V, OBJ, ARG1, NAME, ARG2, ERR) +visit_start_struct(V, NAME, OBJ, ARG1, ARG2, ERR) | -visit_optional(V, ARG1, NAME) +visit_optional(V, NAME, ARG1) | -visit_get_next_type(V, OBJ, ARG1, NAME, ERR) +visit_get_next_type(V, NAME, OBJ, ARG1, ERR) | -visit_type_enum(V, OBJ, ARG1, ARG2, NAME, ERR) +visit_type_enum(V, NAME, OBJ, ARG1, ARG2, ERR) | -VISIT_TYPE(V, OBJ, NAME, ERR) +VISIT_TYPE(V, NAME, OBJ, ERR) ) Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <1454075341-13658-19-git-send-email-eblake@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>

2016-02-06intel_iommu: large page supportJason Wang2-24/+58
Current intel_iommu only supports 4K page which may not be sufficient to cover guest working set. This patch tries to enable 2M and 1G mapping for intel_iommu. This is also useful for future device IOTLB implementation to have a better hit rate. Major work is adding a page mask field on IOTLB entry to make it support large page. And also use the slpte level as key to do IOTLB lookup. MAMV was increased to 18 to support direct invalidation for 1G mapping. Cc: Michael S.

2016-02-06pc: set the OEM fields in the RSDT and the FADT from the SLICLaszlo Ersek1-4/+9
The Microsoft spec about the SLIC and MSDM ACPI tables at <http://go.microsoft.com/fwlink/p/?LinkId=234834> requires the OEM ID and OEM Table ID fields to be consistent between the SLIC and the RSDT/XSDT. That further affects the FADT, because a similar match between the FADT and the RSDT/XSDT is required by the ACPI spec in general. This patch wires up the previous three patches. Cc: "Michael S.
