From 6e04c1bc6120acb86f762bbd58031906492011b7 Mon Sep 17 00:00:00 2001 From: Julien Grall Date: Tue, 14 Jan 2014 01:41:15 +0000 Subject: [PATCH 22/48] xen/netfront: Define PTE flags per architecture PG_* flags doesn't exists on ARM. As this code is not executed on this platform (every guests use auto-translate address), it's possible to define as 0 the flags. --- sys/dev/xen/netfront/netfront.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/sys/dev/xen/netfront/netfront.c b/sys/dev/xen/netfront/netfront.c index b249808..eeaef19 100644 --- a/sys/dev/xen/netfront/netfront.c +++ b/sys/dev/xen/netfront/netfront.c @@ -1365,9 +1365,14 @@ xennet_get_responses(struct netfront_info *np, mcl = np->rx_mcl + pages_flipped; mmu = np->rx_mmu + pages_flipped; +#ifdef __arm__ +# define PTE_FLAGS 0 +#else +# define PTE_FLAGS (PG_RW | PG_V | PG_M | PG_A) +#endif MULTI_update_va_mapping(mcl, (u_long)vaddr, - (((vm_paddr_t)mfn) << PAGE_SHIFT) | PG_RW | - PG_V | PG_M | PG_A, 0); + (((vm_paddr_t)mfn) << PAGE_SHIFT) | + PTE_FLAGS, 0); pfn = (uintptr_t)m->m_ext.ext_arg1; mmu->ptr = ((vm_paddr_t)mfn << PAGE_SHIFT) | MMU_MACHPHYS_UPDATE; -- 2.1.0
