Signed-off-by: Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx> Acked-by: Jan Beulich <jbeulich@xxxxxxxx> --- Changes in V14: - Nothing changed. Only rebase. --- Changes in V13: - drop no_irq_type because of the patch series ( [PATCH for-4.19 0/2] arch/irq: Untangle no_irq_type ) which was merged to staging. - Drop unnessary stubs after rebasing on top of staging ( [PATCH for-4.19 0/2] arch/irq: Untangle no_irq_type ) - implement get_upper_mfn_bound() as BUG_ON("unimplemented") to not introduce max_page which will be dropped in the next patch ( xen/riscv: enable full Xen build ) - remove trainling space in stubs.c after the comment /* guest_access.h */ - drop frametable_base_pdx - drop frametable_virt_end --- Changes in V7-V12: - Only rebase was done. --- Changes in V6: - update the commit in stubs.c around /* ... common/irq.c ... */ - add Acked-by: Jan Beulich <jbeulich@xxxxxxxx> --- Changes in V5: - drop unrelated changes - assert_failed("unimplmented...") change to BUG_ON() --- Changes in V4: - added new stubs which are necessary for compilation after rebase: __cpu_up(), __cpu_disable(), __cpu_die() from smpboot.c - back changes related to printk() in early_printk() as they should be removed in the next patch to avoid compilation error. - update definition of cpu_khz: __read_mostly -> __ro_after_init. - drop vm_event_reset_vmtrace(). It is defibed in asm-generic/vm_event.h. - move vm_event_*() functions from stubs.c to riscv/vm_event.c. - s/BUG/BUG_ON("unimplemented") in stubs.c - back irq_actor_none() and irq_actor_none() as common/irq.c isn't compiled at this moment, so this function are needed to avoid compilation error. - defined max_page to avoid compilation error, it will be removed as soon as common/page_alloc.c will be compiled. --- Changes in V3: - code style fixes. - update attribute for frametable_base_pdx and frametable_virt_end to __ro_after_init. insteaf of read_mostly. - use BUG() instead of assert_failed/WARN for newly introduced stubs. - drop "#include <public/vm_event.h>" in stubs.c and use forward declaration instead. - drop ack_node() and end_node() as they aren't used now. --- Changes in V2: - define udelay stub - remove 'select HAS_PDX' from RISC-V Kconfig because of https://lore.kernel.org/xen-devel/20231006144405.1078260-1-andrew.cooper3@xxxxxxxxxx/ --- xen/arch/riscv/Makefile | 1 + xen/arch/riscv/mm.c | 41 ++++ xen/arch/riscv/setup.c | 8 + xen/arch/riscv/stubs.c | 418 ++++++++++++++++++++++++++++++++++++++++ xen/arch/riscv/traps.c | 25 +++ 5 files changed, 493 insertions(+) create mode 100644 xen/arch/riscv/stubs.c diff --git a/xen/arch/riscv/Makefile b/xen/arch/riscv/Makefile index 1ed1a8369b..60afbc0ad9 100644 --- a/xen/arch/riscv/Makefile +++ b/xen/arch/riscv/Makefile @@ -4,6 +4,7 @@ obj-y += mm.o obj-$(CONFIG_RISCV_64) += riscv64/ obj-y += sbi.o obj-y += setup.o +obj-y += stubs.o obj-y += traps.o obj-y += vm_event.o diff --git a/xen/arch/riscv/mm.c b/xen/arch/riscv/mm.c index ae381e9581..7d09e781bf 100644 --- a/xen/arch/riscv/mm.c +++ b/xen/arch/riscv/mm.c @@ -1,5 +1,6 @@ /* SPDX-License-Identifier: GPL-2.0-only */ +#include <xen/bug.h> #include <xen/compiler.h> #include <xen/init.h> #include <xen/kernel.h> @@ -294,3 +295,43 @@ unsigned long __init calc_phys_offset(void) phys_offset = load_start - XEN_VIRT_START;
