2024-02-29loongarch: Change the UEFI loading mode to loongarchXianglai Li1-3/+26
The UEFI loading mode in loongarch is very different from that in other architectures:loongarch's UEFI code is in rom, while other architectures' UEFI code is in flash. loongarch UEFI can be loaded as follows: -machine virt,pflash=pflash0-format -bios ./QEMU_EFI.fd Other architectures load UEFI using the following methods: -machine virt,pflash0=pflash0-format,pflash1=pflash1-format loongarch's UEFI loading method makes qemu and libvirt incompatible when using NVRAM, and the cost of loongarch's current loading method far outweighs the benefits, so we decided to use the same UEFI loading scheme as other architectures.

2023-08-24hw/loongarch: Fix ACPI processor id off-by-one errorJiajie Chen1-1/+1
In hw/acpi/aml-build.c:build_pptt() function, the code assumes that the ACPI processor id equals to the cpu index, for example if we have 8 cpus, then the ACPI processor id should be in range 0-7. However, in hw/loongarch/acpi-build.c:build_madt() function we broke the assumption. If we have 8 cpus again, the ACPI processor id in MADT table would be in range 1-8. It violates the following description taken from ACPI spec 6.4 table 5.138: If the processor structure represents an actual processor, this field must match the value of ACPI processor ID field in the processor’s entry in the MADT. It will break the latest Linux 6.5-rc6 with the following error message: ACPI PPTT: PPTT table found, but unable to locate core 7 (8) Invalid BIOS PPTT Here 7 is the last cpu index, 8 is the ACPI processor id learned from MADT. With this patch, Linux can properly detect SMT threads when "-smp 8,sockets=1,cores=4,threads=2" is passed: Thread(s) per core: 2 Core(s) per socket: 2 Socket(s): 2 The detection of number of sockets is still wrong, but that is out of scope of the commit.

In theory gsi base can start from 0 on loongarch virt machine, however gsi base is hard-coded in linux kernel loongarch system, else system fails to boot. This patch renames macro PCH_PIC_IRQ_OFFSET with VIRT_GSI_BASE, keeps value unchanged. GSI base is common concept in acpi spec and easy to understand.
