This makes this code common to both the nv04 and nv50 paths. For the moment, we keep the previous behaviour with HDMI/eDP connectors and report them as DVI-D/DP instead. This will be fixed once the rest of the code has been fixed to deal with those types. Signed-off-by:Ben Skeggs <bskeggs@redhat.com>

i2c_entries seems to be the number of i2c entries, so with index equal to this number, we could read invalid data from i2ctable. Fix it. Signed-off-by:

This commit breaks the userspace interface, and requires a new libdrm for nouveau to operate again. The multiple GEM_PUSHBUF ioctls that were present in 0.0.15 for compatibility purposes are now gone, and replaced with the new ioctl which allows for multiple push buffers to be submitted (necessary for hw index buffers in the nv50 3d driver) and relocations to be applied on any buffer. A number of other ioctls (CARD_INIT, GEM_PIN, GEM_UNPIN) that were needed for userspace modesetting have also been removed. Signed-off-by:

This allows us to submit push buffers from any memtype to the hardware. We'll need this ability for VRAM index buffers at some point. Signed-off-by: -

PFIFO on G80 and up has a new mode where the main ring buffer is simply a ring of pointers to indirect buffers containing the actual command/data packets. In order to be able to implement index buffers in the 3D driver we need to be able to submit data-only push buffers right after the cmd packet header, which is only possible using the new command submission method. This commit doesn't make it possible to implement index buffers yet, some userspace interface changes will be required, but it does allow for testing/debugging of the hardware-side support in the meantime.

The nv50 pgraph handler (for example) could reenable pgraph fifo access and that would be bad when pgraph context is being unloaded (we need the guarantee a ctxprog isn't running). Signed-off-by:

This also modifies the unused PRAMIN PT entries to be all zeroes, can't really recall why I used 9/0 initially, just that it didn't work for some reason. It was likely masking a bug elsewhere that's since been fixed. Signed-off-by: -

This commit changes nouveau to construct PTEs which look very much like the ones the binary driver creates. I presume that filling multiple PTEs identically with length flags and the physical address of the start of a block of VRAM is a hint to the memory controller that it need not perform additional page table lookups for that range of addresses.

- We need to disable pgraph fifo access before checking the current channel, otherwise we could still hit a running ctxprog. - The writes to 0x400500 are already handled by pgraph->fifo_access and are therefore redundant, moreover pgraph fifo access should not be reenabled before current context is set as invalid. So remove them altogether. Signed-off-by:

- In the current situation the padding that is added is dangerous to write to, userspace could potentially overwrite parts of another bo. - Depth and stencil buffers are supposed to be large enough in general so the waste of memory should be acceptable. - Alternatives are hiding the padding from users or splitting vram into 2 zones.

Fixes DVI+VGA on my 9400, and likely a lot of other configurations that got broken by the previos DVI-over-DP fix. Signed-off-by: -

With DVI and DP plugged, the DVI clock change interrupts being run can cause DP link training to fail. This adds a spinlock around init table parsing to prevent this. Signed-off-by: -

It appears we aren't required to do memory sizing ourselves on nv40 either. NV40 init tables read a strap from PEXTDEV_BOOT_0 into a CRTC register, and then later use that value to select a memory configuration (written to PFB_CFG0, just like INIT_COMPUTE_MEM on earlier cards) with INIT_IO_RESTRICT_PROG.

We used single shared fbops struct and patched it at fb init time with pointers to the right variant. On mixed multicard, this meant that it was either sending NV50-style commands to all cards, or NV04-style commands to all cards. Signed-off-by:

Test the just-allocated value for NULL rather than some other value. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,y; statement S; @@ x = \(kmalloc\|kcalloc\|kzalloc\)(...); ( if ((x) == NULL) S | if ( - y + x == NULL) S ) // </smpl> Signed-off-by:

nouveau_gem_ioctl_cpu_prep calls ttm_bo_wait without the bo lock held. ttm_bo_wait unlocks that lock, and so must be called with it held. Currently this bug causes libdrm nouveau_bo_busy() to hang the machine. Signed-off-by: Luca Barbieri <luca at luca-barbieri.com> Acked-by:
