| | | | | | | | | | | | | | | | | | | | | | | | Bail out if we don't find an enclosing IOC. Previously, if we didn't find one, we tried to set things up using garbage for the SBA/IOC register address, which causes a crash. This crash only happens if firmware supplies a defective ACPI namespace, so it doesn't fix any problems in the field.

| * agp/hp: fixup hp agp after ACPI changesBjorn Helgaas2010-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 15b8dd53f5ffa changed the string in info->hardware_id from a static array to a pointer and added a length field. But instead of changing "sizeof(array)" to "length", we changed it to "sizeof(length)" (== 4), which corrupts the string we're trying to null-terminate. We no longer even need to null-terminate the string, but we *do* need to check whether we found a HID. If there's no HID, we used to have an empty array, but now we have a null pointer. The combination of these defects causes this oops: Unable to handle kernel NULL pointer dereference (address 0000000000000003) modprobe[895]: Oops 8804682956800 [1] ip is at zx1_gart_probe+0xd0/0xcc0 [hp_agp] http://marc.info/?l=linux-ia64&m=126264484923647&w=2 Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Reported-by: Émeric Maschino <emeric.maschino@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | While investigating a kmemleak detected leak, I encountered the agp_add_bridge function. It appears to be responsible for freeing the agp_bridge_data in the case of a failure, but it is only doing so for some errors. Fix it to always free the bridge data if a failure condition is encountered.

While doing so, it destroys the operation fence, causing nouveau_fence_emit to crash. This patch fixes this bug by taking the fence object out of validate_op and creating it just before emit. The fence pointer is initialized to 0 and unref'ed unconditionally. In addition to fixing the bug, this prevents its reintroduction and simplifies the code.

| | * | drm/nv50: prevent a possible ctxprog hangBen Skeggs2010-01-10

NVIDIA? :P It appears it's possible for a ctxprog to run even while a GPU exception is pending. The GF8 and up ctxprogs appear to have a small snippet of code which detects this, and stalls the ctxprog until it's been handled, which essentially looks like: if (r2 & 0x00008000) { r0 |= 0x80000000; while (r0 & 0x80000000) {} } I don't know of any way that flag would get cleared unless the driver intervenes (and indeed, in the cases I've seen the hang, nothing steps in to automagically clear it for us). This patch causes the driver to clear the flag during the PGRAPH IRQ handler. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This should avoid a race condition on nv0x, if we're doing it with actual PGRAPH objects and a there's a fence within the FIFO DMA fetch area when a context switch kicks in. In that case we get an ILLEGAL_MTHD interrupt as expected, but the values in PGRAPH_TRAPPED_ADDR aren't calculated correctly and they're almost useless (e.g. you can see ILLEGAL_MTHDs for the now inactive channel, with a wrong offset/data pair).
