Subject: drm/nouveau: improve memtiming table parsing

Improves the parsing of the memory timing table on NV50-NV98revA1 chipsets.

Added stepping to drm_nouveau_private to make sure newer NV98 (105M) is
zero rather than incorrect.

Subject: drm/nouveau: working towards a common way to represent engines

There's lots of more-or-less independant engines present on NVIDIA GPUs
these days, and we generally want to perform the same operations on them.
Implementing new ones requires hooking into lots of different places,
the aim of this work is to make this simpler and cleaner.

NV84:NV98 PCRYPT moved over as a test.

From 2703c21a82301f5c31ba5679e2d56422bd4cd404 Mon Sep 17 00:00:00 2001
From: Ben Skeggs <bskeggs@redhat.com>
Date: Fri, 1 Apr 2011 09:50:18 +1000
Subject: drm/nv50/gr: move to exec engine interfaces

This needs a massive cleanup, but to catch bugs from the interface changes
vs the engine code cleanup, this will be done later.

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

From 7a45cd19c95a383d81a7b2f5297958c0c16b5a08 Mon Sep 17 00:00:00 2001
From: Ben Skeggs <bskeggs@redhat.com>
Date: Fri, 1 Apr 2011 10:59:53 +1000
Subject: drm/nvc0/gr: move to exec engine interfaces

Much nicer to do that nv50, the code was pretty much written to expect
such a change in the future.

From a0b1de84fed49a055a3ecbfab67ff9cdea81aa6f Mon Sep 17 00:00:00 2001
From: Ben Skeggs <bskeggs@redhat.com>
Date: Fri, 1 Apr 2011 12:32:03 +1000
Subject: drm/nv20-nv30/gr: move to exec engine interface

A bit of cleanup done along the way, but, like nv40/nv50, needs more.

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

Subject: drm/nouveau: move set_tile_region to nouveau_exec_engine

In the very least VPE (PMPEG and friends) also has this style of tile
region regs, lets make them just work if/when they get added.

Subject: drm/nouveau: remove remnants of nouveau_pgraph_engine from
 nouveau_channel

The nouveau_wait_for_idle() call should hopefully not have been actually
necessary, we *do* wait for the channel to go idle already.  If it's
an issue somehow, the chipset-specific hooks can wait for idle themselves
before taking the lock.

Subject: drm/nv50: improve nv50_pm_get_clock()

Many of the nv50 cards have their shader and/or memory pll
disabled at some stage.
This patch addresses those cases, so that the function
returns the correct frequency.

When the shader pll is disabled, the blob reports 2*core clock
Whereas for memory, the data stored in the vbios. This action
is incorrect as some vbioses store a clock value that is less
than the refference clock of the pll.

Thus we are reporting the reff_clk as it is the frequency the
pll actually operates

v2 - Convert NV_INFO() messages to NV_DEBUG()
Provide more information in the actuall message

Subject: drm/nouveau: Fix a crash at card takedown for NV40 and older cards

NV40 and older cards (pre NV50) reserve a vram bo for the vga memory at
card init. This bo is then freed at card shutdown.  The problem is that
the ttm bo vram manager was already freed. So a crash occurs when the
vga bo is freed. The fix is to free the vga bo prior to freeing the ttm
bo vram manager. There might be other solutions but this seemed the
simplest to me.

Subject: drm/nouveau: fix uninitialised variable warning

Looks like a false positive to me, but, anyways!

Subject: drm/nouveau: recognise DCB connector type 0x41 as LVDS

After looking at a number of different logs, it appears 0x41 likely
indicates the presense of an LVDS panel following the SPWG spec
(http://www.spwg.org/)

Subject: drm/nvc0/gr: calculate some more of our magic numbers

Again, doesn't quite match NVIDIA's, but not sure it really matters.  This
will however, match the same rules we use to calculate the other related
grctx magics.

Subject: drm/nouveau/pm: translate ramcfg strap through ram restrict table

Hopefully this is how we're supposed to correctly handle when the RAMCFG
strap is above the number of entries in timing-related tables.

It's rather difficult to confirm without finding a configuration where
the ram restrict table doesn't map 8-15 back onto 0-7 anyway.  There's
not a single vbios in the repo which is configured differently..

In any case, this is probably still better than potentially reading
outside of the bounds of various tables..

Subject: drm/nva3/clk: better pll calculation when no fractional fb div
 available

The core/mem/shader clocks don't support the fractional feedback divider,
causing our calculated clocks to be off by quite a lot in some cases.  To
solve this we will switch to a search-based algorithm when fN is NULL.

For my NVA8 at PL3, this actually generates identical cooefficients to
the binary driver.  Hopefully that's a good sign, and that does not
break VPLL calculation for someone..

Subject: drm/nouveau: make cursor_set implementation consistent with other
 drivers

When xorg state tracker wants to hide the cursor it calls set_cursor
with NULL buffer_handle and size=0x0, but nouveau refuses to hide it
because size is not 64x64... which is a bit odd. Both radeon and intel
check buffer_handle before validating size of cursor, so make nouveau
implementation consistent with them.
