2012-12-08target-xtensa: implement CACHEATTR SRMax Filippov5-1/+25
In XEA1, the Options for Memory Protection and Translation and the corresponding TLB management instructions are not available. Instead, functionality similar to the Region Protection Option is available through the cache attribute register. See ISA, A.2.14 for details.

2012-12-08finally kill cpudef config section supportEduardo Habkost1-49/+0
The external CPU models were removed on QEMU 1.2, and the support for the "cpudef" config sections was documented as deprecated, but the actual removal of the config section was pending. Now that QEMU 1.3 was released, we can finally kill the support for cpudef config sections, and support only the built-in CPU models from target-i386/cpu.c.

2012-12-06target-i386: Separate feature string parsing from CPU model lookupEduardo Habkost1-23/+46
Instead of parsing the whole cpu_model string inside cpu_x86_find_by_name(), first split it into the CPU model name and the full feature string, then parse the feature string into pieces. When using CPU model classes, those two pieces of information will be used at different moments (CPU model name will be used to find CPU class, feature string will be used after CPU object was created), so making the split in two steps will make it easier to refactor the code later. This should also help on the CPU properties work, that will just need to replace the cpu_x86_parse_featurestr() logic (and can keep the CPU model lookup code as-is).

2012-12-06qdev: qdev_create(): use error_report() instead of hw_error()Eduardo Habkost1-3/+5
hw_error() is specific for fatal hardware emulation errors, not for internal errors related to the qdev object/class abstraction or object initialization. Replace it with an error_report() call, followed by abort(). This will also help reduce dependencies of the qdev code (as hw_error() is from cpus.o, and depends on the CPU list from exec.o).

2012-12-06sysemu.h: Include qemu-types.h instead of qemu-common.hEduardo Habkost1-1/+1

2012-12-06Create qemu-types.h for struct typedefsEduardo Habkost3-61/+63
Instead of keeping all those struct typedefs in qemu-common.h, move it to a header that can be safely included by other headers, containing only the struct typedefs and not pulling in other dependencies. Also, move some of the qdev-core.h typedefs to the new file, too, so other headers don't need to include qdev-core.h only because of DeviceState and other typedefs. This will help us remove qemu-common.h dependencies from some headers later. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
