Subject: [PATCH 00/22] xen/arm: P2M clean-up and fixes
Date: Wed, 20 Jul 2016 17:10:42 +0100 [thread overview]
Message-ID: <1469031064-23344-1-git-send-email-julien.grall@arm.com> (raw)
Hello all,
This patch series contains a bunch of clean-up and fixes for the P2M code on
ARM. The major changes are:
- Restrict usage of get_page_from_gva to the current vCPU
- Deduce the memory attributes from the p2m type
- Switch to read-write lock to improve performance
- Simplify the TLB flush for a given domain
I have provided a branch will all the patches applied on my repo:
git://xenbits/xenbits.xen.org/people/julieng/xen-unstable.git p2m-cleanup-v1
Yours sincerely,
Julien Grall (22):
xen/arm: system: Use the correct parameter name in local_irq_restore
xen/arm: p2m: Pass the vCPU in parameter to get_page_from_gva
xen/arm: p2m: Restrict usage of get_page_from_gva to the current vCPU
xen/arm: p2m: Fix multi-lines coding style comments
xen/arm: p2m: Clean-up mfn_to_p2m_entry
xen/arm: p2m: Use the typesafe MFN in mfn_to_p2m_entry
xen/arm: p2m: Use p2m_is_foreign in get_page_from_gfn to avoid open
coding
xen/arm: p2m: Simplify p2m type check by using bitmask
xen/arm: p2m: Use a whitelist rather than blacklist in
get_page_from_gfn
xen/arm: p2m: Differentiate cacheable vs non-cacheable MMIO
xen/arm: p2m: Find the memory attributes based on the p2m type
xen/arm: p2m: Remove unnecessary locking
xen/arm: p2m: Introduce p2m_{read,write}_{,un}lock helpers
xen/arm: p2m: Switch the p2m lock from spinlock to rwlock
xen/arm: Don't call p2m_alloc_table from arch_domain_create
xen/arm: p2m: Move the vttbr field from arch_domain to p2m_domain
xen/arm: p2m: Don't need to restore the state for an idle vCPU.
xen/arm: p2m: Rework the context switch to another VTTBR in
flush_tlb_domain
xen/arm: p2m: Inline p2m_load_VTTBR into p2m_restore_state
xen/arm: Don't export flush_tlb_domain
xen/arm: p2m: Replace flush_tlb_domain by p2m_flush_tlb
xen/arm: p2m: Pass the p2m in parameter rather the domain when it is
possible
