2024-01-11hw/loongarch/virt: Set iocsr address space per-board rather than percpuBibo Mao
LoongArch system has iocsr address space, most iocsr registers are per-board, however some iocsr register spaces banked for percpu such as ipi mailbox and extioi interrupt status. For banked iocsr space, each cpu has the same iocsr space, but separate data. This patch changes iocsr address space per-board rather percpu, for iocsr registers specified for cpu, MemTxAttrs.requester_id can be parsed for the cpu. With this patches, the total address space on board will be simple, only iocsr address space and system memory, rather than the number of cpu and system memory.

2023-11-07target/loongarch: Declare QOM definitions in 'cpu-qom.h'Philippe Mathieu-Daudé
"target/foo/cpu.h" contains the target specific declarations. A heterogeneous setup need to access target agnostic declarations (at least the QOM ones, to instantiate the objects). Our convention is to add such target agnostic QOM declarations in the "target/foo/cpu-qom.h" header. Add a comment clarifying that in the header. Extract QOM definitions from "cpu.h" to "cpu-qom.h".

2023-07-24target/loongarch: Fix the CSRRD CPUID instruction on big endian hostsThomas Huth
The test in tests/avocado/machine_loongarch.py is currently failing on big endian hosts like s390x. By comparing the traces between running the QEMU_EFI.fd bios on a s390x and on a x86 host, it's quickly obvious that the CSRRD instruction for the CPUID is behaving differently. And indeed: The code currently does a long read (i.e. 64 bit) from the address that points to the CPUState->cpu_index field (with tcg_gen_ld_tl() in the trans_csrrd() function). But this cpu_index field is only an "int" (i.e. 32 bit). While this dirty pointer magic works on little endian hosts, it of course fails on big endian hosts. Fix it by using a proper helper function instead. Message-Id: <20230720175307.854460-1-thuth@redhat.com> Reviewed-by: Song Gao <gaosong@loongson.cn> Signed-off-by: Thomas Huth <thuth@redhat.com>
