* drm/nv50: parse/use some more de-magiced parts of gpio table entriesBen Skeggs2010-04-08

* drm/nouveau: store raw gpio table entry in bios gpio structsBen Skeggs2010-04-08
| | | | | | And use our own version of the GPIO table for the INIT_GPIO opcode. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nv50: another dodgy DP hackBen Skeggs2010-04-08
| | | | | | | | Allows *some* DP cards to keep working in some corner cases that most people shouldn't hit. I hit it all the time with development, so this can stay for now. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nv50: punt hotplug irq handling out to workqueueBen Skeggs2010-04-08
| | | | | | | On DP outputs we'll likely end up running vbios init tables here, which may sleep. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nv50: preserve an unknown SOR_MODECTRL value for DP encodersBen Skeggs2010-04-08
| | | | | | | | | This value interacts with some registers we don't currently know how to program properly ourselves. The default of 5 that we were using matches what the VBIOS on early DP cards do, but later ones use 6, which would cause nouveau to program an incorrect mode on these chips.

* drm/nv40: rework lvds table parsingBen Skeggs2010-04-08
| | | | | | | | | | | All indications seem to be that the version 0x30 table should be handled the same way as 0x40 (as used on G80), at least for the parts that we currently try use. This commit cleans up the parsing to make it clearer about what we're actually trying to achieve, and unifies the 0x30/0x40 parsing. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nouveau: detect vram amount once, and save the valueBen Skeggs2010-04-08
| | | | | | | | | | As opposed to repeatedly reading the amount back from the GPU every time we need to know the VRAM size. We should now fail to load gracefully on detecting no VRAM, rather than something potentially messy happening. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

* drm/nouveau: Make use of TTM busy_placements.Francisco Jerez2010-04-08
| | | | | | | | | Previously we were filling it the same as "placements", but in some cases there're valid alternatives that we were ignoring completely. Keeping a back-up memory type helps on several low-mem situations. Signed-off-by: Francisco Jerez <currojerez@riseup.net> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
* drm/nv50: add more 0x100c80 flushy magicBen Skeggs2010-04-08
| | | | | | | | | | Fixes the !vbo_fifo path in the 3D driver on certain chipsets. Still not really any good idea of what exactly the magic achieves, but it makes things work. While we're at it, in the PCIEGART path, flush on unbinding also. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

| | * sh: Support CPU affinity masks for INTC controllers.Paul Mundt2010-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This hooks up the ->set_affinity() for the INTC controllers, which can be done as just a simple copy of the cpumask. The enable/disable paths already handle SMP register strides, so we just test the affinity mask in these paths to determine which strides to skip over. The early enable/disable path happens prior to the IRQs being registered, so we have no affinity mask established at that point, in which case we just default to CPU_MASK_ALL. This is left as it is to permit the force enable/disable code to retain existing semantics. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These parameters should be passed as cpu endian because we change it to little endian inside usb_control_msg(). On x86 cpu_to_le16() doesn't do anything so either way works but I think the original code would break on big endian systems. I removed the masks as well because that usb_control_msg() parameters are __u16 so we already only use the lower bits.

This doesn't add pressure to the IOMMU allocator. However, some drivers don't support getting large merged segments coming back from *_map_sg(). Most drivers don't have this problem; it is safe to say Y here. It's out of date. Long ago, drivers didn't have a way to tell IOMMUs about their segment length limit (that is, the maximum segment length that they can handle). So IOMMUs merged as many segments as possible and gave too large segments to drivers. dma_get_max_seg_size() was introduced to solve the above problem. Device drives can use the API to tell IOMMU about the maximum segment length that they can handle. In addition, the default limit (64K) should be safe for everyone. So this config option seems to be unnecessary. Note that this config option just enables users to disable the virtual merging by default. Users can still disable the virtual merging by the boot parameter. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
