[PATCH v3 00/43] Add LoongArch softmmu support
Posted by Xiaojuan Yang 2 years ago
Hi All,

As this series only supports running binary files in ELF format, and does not depend on
BIOS and kernel file. so this series are changed from RFC to patch v1.


The manual:
  - https://github.com/loongson/LoongArch-Documentation/releases/tag/2022.03.17

Old series:
  - https://patchew.org/QEMU/20220328125749.2918087-1-yangxiaojuan@loongson.cn/
  - https://patchew.org/QEMU/20220106094200.1801206-1-gaosong@loongson.cn/

Thanks.
Xiaojuan

-----
v3:

  - Add Check csr_names.
  - Drop CSR_CPUID, use cpu->cpu_index.
  - Fixed loongarch extioi device emulation. ipmap and coremap register change to 32bits.
  - Check_iocsr() function moved to loongarch_ipi_writel().
  - Pch_pic/msi use qdev_init_gpio_out() to init irq, and use qdev_connect_gpio_out() to connect irq.
  - Load elf function moved to hw/loongarch/loongson.c

v2:
  - Improvents to CSR/IOCSR instructions translation.
  - Fixed extioi device emulation. It is represented by only one memory region.
  - Fixed IPI device emulation. The registers are represented with uint64_t.
  - Use do_cpu_reset() and cpu_set_pc() to specify the load address. 

v2: https://patchew.org/QEMU/20220425091027.2877892-1-yangxiaojuan@loongson.cn/
v1: https://patchew.org/QEMU/20220415094058.3584233-1-yangxiaojuan@loongson.cn/

Re: [PATCH v3 00/43] Add LoongArch softmmu support
Posted by yangxiaojuan 1 year, 12 months ago
Hi  Richard and Mark,
Could you help us review the patch [1] ?

[1] :
[PATCH v3 34/43] hw/intc: Add LoongArch extioi interrupt
[PATCH v3 38/43] hw/loongarch: Add LoongArch ls7a rtc device support
[PATCH v3 39/43] hw/loongarch: Add LoongArch load elf function.
[PATCH v3 40/43] hw/loongarch: Add LoongArch ls7a acpi device support

Thanks.
Xiaojuan
