lib: Handle page/access fault caused by unpriv load/store

2019-05-24T02:52:47Z

The unpriv load/store instruction from M-mode can cause page/access fault to M-mode if S-mode page table did not have mappings OR it did not have PMP access permission. To tackle this, we redirect trap back to S-mode if unpriv load/store instruction traps in M-mode. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: Implement sfence.vma correctly.

2019-03-12T16:37:25Z

Currently, OpenSBI doesn't distinguish between sfence.vma and sfence.vm asid calls. Moreover, it ignores the page ranges and just flush entire TLB everytime. Fix the sfence implementation by keeping all the tlb flush info in scratch area. The relevant Linux kernel code was added by https://patchwork.kernel.org/project/linux-riscv/list/?series=89695 However, this patch is backward compatible with older version kernel that doesn't have the above patches as well. Fixes #87 Signed-off-by: Atish Patra

lib: Send IPI for all harts to hang on system shutdown

2019-02-18T03:51:58Z

In case the platform specific method for shutting down the system fails (or is not implemented), at least make sure that all harts hang instead of just the current hart. Signed-off-by: Nick Kossifidis

lib: Simplify sbi_platform early_init() and final_init() hooks

2018-12-27T04:05:09Z

Instead of having separate early_init() and final_init() hooks for cold and warm boot, this patch updates struct sbi_platform to have just one early_init() and one final_init() hook. The type of boot (cold or warm) is now a boolean flag parameter for the updated early_init() and final_init() hooks. Signed-off-by: Anup Patel
