[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v6 00/23] Introduce enablemenant of dom0less
This patch series reprensent a bunch of patches necessary to enable common part of Dom0less. The stuff necessary to start/launch domains will be introduced separately. CI tests: https://gitlab.com/xen-project/people/olkur/xen/-/pipelines/2690872826 --- Changes in v6: - Merged to upstream/staging: - xen: arm: move declaration of map_device_irqs_to_domain() to common header - xen/Kconfig: introduce HAS_STATIC_MEMORY - xen/riscv: rename enum intc_version to intc_variant - xen/riscv: implement prerequisites for domain_create() - Move UBSAN fix ("xen: introduce CONFIG_HAS_SHARED_INFO for archs without a shared page") to this patch series as it is connected to "xen/Kconfig: introduce HAS_STATIC_MEMORY". - Address the comments from ML. --- Changes in v5: - Add new patch (xen/riscv: do a 4th linking pass if necessary) which fixes randconfig job issue. - Address comments from ML. --- Changes in v4: - Address comments from ML. --- Changes in v3: - Drop dependency from other patch series ([1] https://lore.kernel.org/xen-devel/cover.1778140240.git.oleksii.kurochko@xxxxxxxxx/T/#t) as it was merged. - Reorder patches: - move common patches to the start. - Move some patches to separate patch series (will be introduced later) - Address comments from ML. --- Changes in v2: - Move patch "[PATCH v1 04/27] xen/riscv: rework G-stage mode handling" to patch series [1] - Address the comments from ML. - The following patches were folded into one: # xen/riscv: implement init_intc_phandle() # xen/riscv: call do_initcalls() in start_xen() # xen/riscv: setup system domains - The following patch were folded into one: # xen/riscv: add vaplic access check # xen/riscv: emulate guest writes to virtual APLIC MMIO # xen/riscv: emulate guest reads from virtual APLIC MMIO - Add new bug fix, not really necessary to this patch series: xen/riscv: manage IRQ_DISABLED flag in APLIC irq enable/disable callbacks --- Oleksii Kurochko (23): xen: introduce CONFIG_HAS_SHARED_INFO for archs without a shared page xen/dom0less: turn max_init_domid into a common variable xen: arm: update p2m_set_allocation() prototype xen/riscv: Implement ARCH_PAGING_MEMPOOL xen/riscv: Implement construct_domain() xen/riscv: introduce guest riscv,isa string xen/riscv: implement make_cpus_node() xen/riscv: implement make_timer_node() xen/riscv: implement make_arch_nodes() xen/riscv: introduce init interrupt controller operations xen/riscv: implement make_intc_domU_node() xen/riscv: introduce aia_init() and aia_usable() xen/riscv: introduce per-vCPU IMSIC state xen/riscv: introduce minimal virtual APLIC (vAPLIC) infrastructure xen/riscv: introduce (de)initialization helpers for vINTC xen/riscv: generate IMSIC DT node for guest domains xen/riscv: create APLIC DT node for guest domains xen/riscv: implement IRQ routing for device passthrough xen/riscv: implement init_intc_phandle() xen/riscv: initialize RCU, scheduler, and system domains in start_xen() xen/riscv: provide init_vuart() xen/riscv: add initial dom0less infrastructure support xen/riscv: do a 4th linking pass if necessary xen/arch/arm/Kconfig | 1 + xen/arch/arm/include/asm/p2m.h | 1 -
