Subject: [PATCH v9 0/8] xen/arm: Split MMU code as the prepration of MPU work
Date: Thu, 16 Nov 2023 22:50:24 +0800 [thread overview]
Message-ID: <20231116145032.1651305-1-Henry.Wang@arm.com> (raw)
Based on the discussion in the Xen Summit [1], sending this series out after
addressing the comments in v8 [2] as the preparation work to add MPU support.
Mostly code movement and function folding, with some of Kconfig and build
system (mainly Makefiles) adjustment.
This series is based on:
6cd046c501 xen/arm: Enlarge identity map space to 10TB

Henry Wang (6):
xen/arm: Split page table related code to mmu/pt.c
xen/arm: Split MMU system SMP MM bringup code to mmu/smpboot.c
xen/arm: Fold mmu_init_secondary_cpu() to head.S
xen/arm: Extract MMU-specific MM code
xen/arm: Split MMU-specific setup_mm() and related code out
xen/arm: Fold pmap and fixmap into MMU system
Penny Zheng (2):
xen/arm: Rename init_secondary_pagetables() to prepare_secondary_mm()
xen/arm: mmu: move MMU specific P2M code to mmu/p2m.{c,h}
