hangliu1	2ab068400b	hv: multiarch: move some function to common ... move some funcitons like hpa2hva to common file. change some files to include file from asm/pgtable.h to common/pgtable.h Tracked-On: #8831 Signed-off-by: hangliu1 <hang1.liu@intel.com> Reviewed-by: Fei Li <fei1.li@intel.com> Acked-by: Wang, Yu1 <yu1.wang@intel.com>	2025-10-21 14:14:55 +08:00
Haicheng Li	fb82f3b931	hv: implement cpu dead and cpu idle for riscv ... implement arch_cpu_dead and arch_cpu_do_idle for riscv, arch_cpu_dead and arch_cpu_do_idle will be called by common module.

Jian Jun Chen	17c9a4d7be	hv: riscv: implement basic logic to bring up APs ... This patch adds the basic logics to bring up all APs in the C entry of BSP boot. The mapping between logcial CPU IDs and physical hart IDs is setup based on the pre-generated data from config tool by parsing the device tree. Logical CPU ID BSP_CPU_ID will always map to the BSP hart ID. The per pCPU logic ID is saved in tp register.

Jian Jun Chen	1949c0b52f	hv: riscv: add get/set_pcpu_id and start_pcpus implementation ... Use tp register to hold the current logical CPU ID. This follows the same design as x86 which uses MSR_IA32_SYSENTER_CS for the same purpose. riscv uses SBI HSM to start the APs.

Haicheng Li	052a58d87d	hv: multiarch: riscv: add two cpu interfaces ... add wait_sync_change and arch_get_pcpu_num implementation for riscv. MAX_PCPU_NUM comes from board_info.h generated by config tool. v2->v3: remove riscv cpu.c include asm/cpu.h v1->v2: implement arch_get_num_available_cpus(); Tracked-On: #8801 signed-off-by: Haicheng Li <haicheng.li@intel.com> Co-developed-by: hangliu1 <hang1.liu@intel.com> Signed-off-by: hangliu1 <hang1.liu@intel.com> Reviewed-by: Wang, Yu1 <yu1.wang@intel.com> Reviewed-by: Liu, Yifan1 <yifan1.liu@intel.com> Acked-by: Wang, Yu1 <yu1.wang@intel.com>	2025-09-19 15:04:55 +08:00
