Hi all, I spent the last few months looking at Xen boot and memory management to make it simpler, more efficient and also more compliant in respect of the Arm Arm. The full rework is quite consequence (already 150 patches and I haven't yet finished!), so I am planning to send in smaller part over the next few weeks. In this first part, I focus on reworking how we flush the TLBs in Xen. The main addition for this version is to prevent Xen booting on AIVIVT instruction caches (see patch #1). For all the other changes, see each patch. Cheers, Julien Grall (8): xen/arm: Don't boot Xen on platform using AIVIVT instruction caches xen/arm: mm: Consolidate setting SCTLR_EL2.WXN in a single place xen/arm: Remove flush_xen_text_tlb_local() xen/arm: tlbflush: Clarify the TLB helpers name xen/arm: page: Clarify the Xen TLBs helpers name xen/arm: Gather all TLB flush helpers in tlbflush.h xen/arm: tlbflush: Rework TLB helpers xen/arm: mm: Flush the TLBs even if a mapping failed in create_xen_entries xen/arch/arm/mm.c | 69 ++++++++++++++++++++++----------- xen/arch/arm/p2m.c | 6 +-- xen/arch/arm/setup.c | 5 +++ xen/arch/arm/smp.c | 2 +- xen/arch/arm/traps.c | 2 +- xen/include/asm-arm/arm32/flushtlb.h | 71 +++++++++++++++++++--------------- xen/include/asm-arm/arm32/page.h | 48 ++++------------------- xen/include/asm-arm/arm64/flushtlb.h | 75 ++++++++++++++++++++---------------- xen/include/asm-arm/arm64/page.h | 49 +++-------------------- xen/include/asm-arm/flushtlb.h | 38 ++++++++++++++++++ xen/include/asm-arm/page.h | 38 ------------------ xen/include/asm-arm/processor.h | 5 +++ 12 files changed, 194 insertions(+), 214 deletions(-)
