From 73044f05a4ac65f2df42753e9566444b9d2a660f Mon Sep 17 00:00:00 2001 From: Glauber de Oliveira Costa Date: Mon, 7 Jan 2008 11:05:27 -0200 Subject: lguest: make hypercalls use the vcpu struct this patch changes do_hcall() and do_async_hcall() interfaces (and obviously their callers) to get a vcpu struct. Again, a vcpu services the hypercall, not the whole guest Signed-off-by: Glauber de Oliveira Costa Signed-off-by: Rusty Russell --- drivers/lguest/lg.h | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) (limited to 'drivers/lguest/lg.h') diff --git a/drivers/lguest/lg.h b/drivers/lguest/lg.h index bfca2716ad11..a4ebd415fa27 100644 --- a/drivers/lguest/lg.h +++ b/drivers/lguest/lg.h @@ -43,6 +43,10 @@ struct lguest; struct lg_cpu { unsigned int id; struct lguest *lg; + + /* If a hypercall was asked for, this points to the arguments. */ + struct hcall_args *hcall; + u32 next_hcall; }; /* The private info the thread maintains about the guest. */ @@ -65,13 +69,9 @@ struct lguest u32 cr2; int halted; int ts; - u32 next_hcall; u32 esp1; u8 ss1; - /* If a hypercall was asked for, this points to the arguments. */ - struct hcall_args *hcall; - /* Do we need to stop what we're doing and return to userspace? */ int break_out; wait_queue_head_t break_wq; @@ -178,9 +178,9 @@ void page_table_guest_data_init(struct lguest *lg); void lguest_arch_host_init(void); void lguest_arch_host_fini(void); void lguest_arch_run_guest(struct lg_cpu *cpu); -void lguest_arch_handle_trap(struct lguest *lg); -int lguest_arch_init_hypercalls(struct lguest *lg); -int lguest_arch_do_hcall(struct lguest *lg, struct hcall_args *args); +void lguest_arch_handle_trap(struct lg_cpu *cpu); +int lguest_arch_init_hypercalls(struct lg_cpu *cpu); +int lguest_arch_do_hcall(struct lg_cpu *cpu, struct hcall_args *args); void lguest_arch_setup_regs(struct lguest *lg, unsigned long start); /* /switcher.S: */ @@ -191,7 +191,7 @@ int lguest_device_init(void); void lguest_device_remove(void); /* hypercalls.c: */ -void do_hypercalls(struct lguest *lg); +void do_hypercalls(struct lg_cpu *cpu); void write_timestamp(struct lguest *lg); /*L:035 -- cgit v1.2.2
