Subject: [PATCH 0/9] cputlb: Various cleanups
Date: Thu, 9 Jan 2020 13:48:58 +1100 [thread overview]
Message-ID: <20200109024907.2730-1-richard.henderson@linaro.org> (raw)
I had a conversation with Alistair Francis at KVM forum about
being able to represent ASIDs "properly". This lead to the idea
that target-specific code might be able to cache TLBs outside of
the "main" NB_MMU_MODES -- possibly thousands of them.
This goes nowhere near that far. But it does begin edging toward
the possibility of having a
struct CPUTLBSaved {
CPUTLBDesc d;
CPUTLBDescFast f;
};
by moving some of the most basic routines to use CPUTLBDesc and
CPUTLBDescFast directly instead of always using an mmu_idx.
I'm not sure how much time I'll have to go further along these
lines, but what I have so far still looks like a cleanup.

Richard Henderson (9):
cputlb: Merge tlb_table_flush_by_mmuidx into
tlb_flush_one_mmuidx_locked
cputlb: Make tlb_n_entries private to cputlb.c
cputlb: Pass CPUTLBDescFast to tlb_n_entries and sizeof_tlb
cputlb: Hoist tlb portions in tlb_mmu_resize_locked
cputlb: Hoist tlb portions in tlb_flush_one_mmuidx_locked
cputlb: Split out tlb_mmu_flush_locked
cputlb: Partially merge tlb_dyn_init into tlb_init
cputlb: Initialize tlbs as flushed
cputlb: Hoist timestamp outside of loops over tlbs
