Introduce generic headers
|

|
Some headers are common between several architectures, so the current patch series provide them. Another one reason to have them as generic is a simplification of adding support necessary to make a complete Xen build as it was/is being done in the patch series [1] and [2]. Also, instead of providing generic/stub headers, it was used "#ifdef CONFIG_* #include <asm/*.h> #endif" instead of providing empty headers. This patch series is a pre-requisite for "Enable build of full Xen for RISC-V" [3]. [1] https://lore.kernel.org/xen-devel/cover.1694543103.git.sanastasio@raptorengineering.com/ [2] https://lore.kernel.org/xen-devel/cover.1692181079.git.oleksii.kurochko@gmail.com/ [3] https://lore.kernel.org/xen-devel/cover.1700761381.git.oleksii.kurochko@gmail.com/ --- Changes in V6: - Fix the build script to work properly with EXTRA_FIXED_RANDCONFIG. - Introduce separate randconfig yaml with fixed configs for RISC-V. - Disable CONFIG_GRANT_TABLE and CONFIG_MEM_ACCESS for PPC and RISC-V. - Remove change in Kconfig/common for CONFIG_GRANT_TABLE and CONFIG_MEM_ACCESS. - Rebase on top of the latest staging. --- Changes in V5: - Update the patch series message as patch related to delay.h was merged. - Rebase on top of staging because half of the patches of the patch series were merged to staging branch. - Add A-by for some of the patches. - Add "depends on X86 || Arm" for CONFIG_GRANT_TABLE and CONFIG_MEM_ACCESS to be sure it won't be turned on by randconfig in CI. - Partly switch Arm and PPC to asm-generic/monitor.h. - Some other minor changes --- Changes in V4: - Update the cover letter message - Add Reviewed-by/Acked-by for patches: [PATCH v3 01/14] xen/asm-generic: introduce stub header paging.h [PATCH v3 03/14] xen/asm-generic: introduce generic hypercall.h [PATCH v3 04/14] xen/asm-generic: introduce generic header iocap.h [PATCH v3 05/14] xen/asm-generic: introduce stub header <asm/random.h> [PATCH v3 06/14] xen/asm-generic: introduce generic header percpu.h [PATCH v3 07/14] xen/asm-generic: introduce generalized hardirq.h [PATCH v3 08/14] xen/asm-generic: introduce generic div64.h header [PATCH v3 09/14] xen/asm-generic: introduce generic header altp2m.h [PATCH v3 10/14] xen/asm-generic: introduce stub header monitor.h [PATCH v3 11/14] xen/asm-generic: introduce stub header numa.h [PATCH v3 12/14] xen/asm-generic: introduce stub header softirq.h - Fix some code style and minor issues. - Use asm-generic version of device.h for Arm and PPC. --- Changes in V3: - Update the commit message of the cover letter. - Drop the following patch as it can be arch-specific enough: * [PATCH v2 09/15] xen/asm-generic: introduce generic header smp.h - Drop correspondent arch specific headers and use asm-generic version of a header. - Back to the patch series patches: * xen: ifdef inclusion of <asm/grant_table.h> in <xen/grant_table.h> * xen/asm-generic: ifdef inclusion of <asm/mem_access.h> --- Changes in V2: - Update the commit message of the cover letter. - Drop the following patches because they are arch-specific or was sent as a separate patch: - xen/asm-generic: introduce stub header event.h - xen/asm-generic: introduce stub header spinlock.h - [PATCH v1 03/29] xen/asm-generic: introduce stub header cpufeature.h - [PATCH v1 07/29] xen/asm-generic: introduce stub header guest_atomics.h - [PATCH v1 10/29] xen/asm-generic: introduce stub header iommu.h - [PATCH v1 12/29] xen/asm-generic: introduce stub header pci.h because separate patch was sent [5] - [PATCH v1 14/29] xen/asm-generic: introduce stub header setup.h - [PATCH v1 15/29] xen/asm-generic: introduce stub header xenoprof.h because of [3]. - [PATCH v1 16/29] xen/asm-generic: introduce stub header flushtlb.h - [PATCH v1 22/29] xen/asm-generic: introduce stub header delay.h because of [3] - [PATCH v1 23/29] xen/asm-generic: introduce stub header domain.h - [PATCH v1 24/29] xen/asm-generic: introduce stub header guest_access.h - [PATCH v1 25/29] xen/asm-generic: introduce stub header irq.h ( probably not so generic as I expected, I'll back to it if it will be necessary in the future ) - [PATCH v1 28/29] xen/asm-generic: introduce stub header p2m.h ( probably not so generic as I expected, I'll back to it if it will be necessary in the future ) - For the rest of the patches please look at changes for each patch separately. --- Oleksii Kurochko (9): automation: ensure values in EXTRA_FIXED_RANDCONFIG are separated by new line automation: introduce fixed randconfig for RISC-V xen/asm-generic: introduce generic div64.h header xen/asm-generic: introduce stub header monitor.h xen/asm-generic: introduce stub header numa.h xen/asm-generic: introduce stub header softirq.h xen: ifdef inclusion of <asm/grant_table.h> in <xen/grant_table.h> xen/asm-generic: ifdef inclusion of <asm/mem_access.h> xen/asm-generic: introduce generic device.h automation/gitlab-ci/build.yaml | 8 +- .../gitlab-ci/riscv-fixed-randconfig.yaml | 7 + automation/scripts/build | 6 +- xen/arch/arm/device.c | 15 ++- xen/arch/arm/domain_build.c | 3 +- xen/arch/arm/gic-v2.c | 4 +- xen/arch/arm/gic-v3.c | 6 +- xen/arch/arm/gic.c | 4 +- xen/arch/arm/include/asm/Makefile | 3 + xen/arch/arm/include/asm/div64.h | 8 +- xen/arch/arm/include/asm/monitor.h | 28 +--- xen/arch/arm/p2m.c | 1 + xen/arch/arm/traps.c | 1 + xen/arch/ppc/configs/ppc64_defconfig | 1 + xen/arch/ppc/include/asm/Makefile | 4 + xen/arch/ppc/include/asm/device.h | 53 -------- xen/arch/ppc/include/asm/div64.h | 14 -- xen/arch/ppc/include/asm/grant_table.h | 5 -
