From cd998f5e4e7fcffc2b88c0b04500e1fba2ad0e7e Mon Sep 17 00:00:00 2001 From: andrew Date: Sat, 22 Sep 2012 06:41:56 +0000 Subject: Create a common set_stackptrs in sys/arm/machdep.c. On single core devices set_stackptrs is only ever called with cpu = 0 in initarm and will be identical to the existing function. On SMP this needs to be implemented for sys/arm/mp_machdep.c, but the implementations are identical for each SoC. --- sys/arm/xscale/i80321/ep80219_machdep.c | 16 +--------------- 1 file changed, 1 insertion(+), 15 deletions(-) (limited to 'sys/arm/xscale/i80321/ep80219_machdep.c') diff --git a/sys/arm/xscale/i80321/ep80219_machdep.c b/sys/arm/xscale/i80321/ep80219_machdep.c index ce1a949..134647b 100644 --- a/sys/arm/xscale/i80321/ep80219_machdep.c +++ b/sys/arm/xscale/i80321/ep80219_machdep.c @@ -104,11 +104,6 @@ __FBSDID("$FreeBSD$"); /* this should be evenly divisable by PAGE_SIZE / L2_TABLE_SIZE_REAL (or 4) */ #define NUM_KERNEL_PTS (KERNEL_PT_AFKERNEL + KERNEL_PT_AFKERNEL_NUM) -/* Define various stack sizes in pages */ -#define IRQ_STACK_SIZE 1 -#define ABT_STACK_SIZE 1 -#define UND_STACK_SIZE 1 - extern u_int data_abort_handler_address; extern u_int prefetch_abort_handler_address; extern u_int undefined_handler_address; @@ -329,16 +324,7 @@ initarm(struct arm_boot_params *abp) * Since the ARM stacks use STMFD etc. we must set r13 to the top end * of the stack memory. */ - - - set_stackptr(PSR_IRQ32_MODE, - irqstack.pv_va + IRQ_STACK_SIZE * PAGE_SIZE); - set_stackptr(PSR_ABT32_MODE, - abtstack.pv_va + ABT_STACK_SIZE * PAGE_SIZE); - set_stackptr(PSR_UND32_MODE, - undstack.pv_va + UND_STACK_SIZE * PAGE_SIZE); - - + set_stackptrs(0); /* * We must now clean the cache again.... -- cgit v1.1
