Subject: [RFC PATCH 0/5] powerpc/64s/radix: Use non-atomic ops for PTE
Date: Sun, 20 Dec 2020 09:48:08 +1000 [thread overview]
Message-ID: <20201219234813.830747-1-npiggin@gmail.com> (raw)
This is not entirely settled because of future compatibility concern
but in terms of Linux code and existing processors I think the approach
works.
Thanks,
Nick
Nicholas Piggin (5):
powerpc/64s: update_mmu_cache inline the radix test
powerpc/64s: implement mm_nmmu_has_tlbs
powerpc/64s: add CONFIG_PPC_NMMU for nest MMU support
powerpc/64s/radix: implement complete radix__ptep_get_and_clear_full
powerpc/64s/radix: Use non-atomic PTE updates if the MMU does not
modify the PTE
