From 06f0cce43a32bd2357cea1d8733bba48693d556b Mon Sep 17 00:00:00 2001 From: Alex Ivanov Date: Wed, 10 Jul 2013 21:14:55 +0200 Subject: [PATCH] parisc: agp/parisc-agp: allow binding of user memory to the AGP GART MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Allow binding of user memory to the AGP GART on systems with HP Quicksilver AGP bus. This resolves 'bind memory failed' error seen in dmesg: [29.365973] [TTM] AGP Bind memory failed. … [29.367030] [drm] Forcing AGP to PCI mode The system doesn't more fail to bind the memory, and hence not falling back to the PCI mode (if other failures aren't detected). This is just a simple write down from the following patches: agp/amd-k7: Allow binding user memory to the AGP GART agp/hp-agp: Allow binding user memory to the AGP GART Signed-off-by: Alex Ivanov Cc: # 3.10 Signed-off-by: Helge Deller --- drivers/char/agp/parisc-agp.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/char/agp/parisc-agp.c b/drivers/char/agp/parisc-agp.c index bf5d247..15f2e70 100644 --- a/drivers/char/agp/parisc-agp.c +++ b/drivers/char/agp/parisc-agp.c @@ -129,7 +129,8 @@ parisc_agp_insert_memory(struct agp_memory *mem, off_t pg_start, int type) off_t j, io_pg_start; int io_pg_count; - if (type != 0 || mem->type != 0) { + if (type != mem->type || + agp_bridge->driver->agp_type_to_mask_type(agp_bridge, type)) { return -EINVAL; } @@ -175,7 +176,8 @@ parisc_agp_remove_memory(struct agp_memory *mem, off_t pg_start, int type) struct _parisc_agp_info *info = &parisc_agp_info; int i, io_pg_start, io_pg_count; - if (type != 0 || mem->type != 0) { + if (type != mem->type || + agp_bridge->driver->agp_type_to_mask_type(agp_bridge, type)) { return -EINVAL; } -- 2.7.4
