Subject: [PATCH 00/15] GMA500 KMS and GEM

This patch series versus linux-next 2011/06/08 fixes various bugs including a
nasty pinning bug found by Andre Bartke.

With these patches applied the driver passes the various GEM tests and you can
use the KMS tools and test sets to set modes and display stuff from GEM
buffers including those mapped from main memory via the GTT.

You can't yet take a GEM handle of the system frame buffer. That requires
a trivial patch to drm_gem and a similar trivial patch to this driver.

The two main remaining tasks now are to provide a 2D command interface for the
X server including support for blitting between GEM objects (so we need relocs)
and to clean the code up.

Vblank support is also possible but doesn't seem terribly useful.

Subject: [PATCH 02/15] gma500: Skip bogus LVDS VBT mode and check for LVDS before adding backlight

From: Patrik Jakobsson <[email protected]>

On the Fit-PC2 the VBT reports an invalid fixed panel mode for LVDS, this gets
in the way for SDVO. This patch makes VBT parsing skip the invalid mode. When
there is no LVDS output the backlight support crashes so the patch also checks
for this before enabling it.

Subject: [PATCH 03/15] gma500: Make GTT pages uncached

From: Alan Cox <[email protected]>

Clean up the GTT code a bit, make the pages uncached and go via the proper
interfaces. This avoids any aliasing problems.

On the CPU side we need to access the pages via their true addresses not via
the GTT. This is fine for GEM created fb objects for X. For the kernel fb
when not in stolen RAM we are going to need to use vm_map_ram() and hope we
have enough virtual address space to steal.

Subject: [PATCH 04/15] gma500: Ensure the frame buffer has a linear virtual mapping

From: Alan Cox <[email protected]>

We need this for the framebuffer in order to ensure that the kernel
framebuffer layer can handle it when using KMS. Except for the base
framebuffer this isn't a concern.

Add an npage field to the gtt as too many copies of the page calculation
are getting spread around the code.

Subject: [PATCH 06/15] staging/gma500: get control from firmware framebuffer if conflicts

From: Michael Chang <[email protected]>

Many Linux distributions would enable vesafb in order to display
early stage boot splash. In this case, we will get garbled X
Window screen if running X fbdev on psbfb.

This is because fb0 is occupied by vesafb while psbfb is on fb1.
They tried to drive the same pieces of hardware at the same
time. With unmodified X start-up, it would try to use default
fb0 framebuffer device and unfortunately it is now broken
becaues fb1 supersedes it.

We should let psbfb takeover framebuffer control from vesafb
to get around this problem.

From: Alan Cox <[email protected]>

Restructure this to work the same way as the i915 frame buffer does. That
cleans up various chunks of code.

We can now set a mode in modetest but mode restore is a bit iffy

Subject: [PATCH 09/15] gma500: Do sane FB cleanup

From: Alan Cox <[email protected]>

If we get a user frame buffer destroyed which is being displayed then clean
up the mess nicely. We can now run a slightly modified modetest including setting
modes, and handling crashes.

Modetest still blows up but this is because libdrm 2.4.25 is busted.

Subject: [PATCH 12/15] gma500: 2D acceleration tidying

From: Alan Cox <[email protected]>

We have a FIXME to do the power management for which the framework now
exists, and we also need to deal with an erratum. Some operations exactly 8
pixels wide or high fail. The work around is to do two smaller ones (see
the Intel released X driver bits) but for console quite frankly if it's
8bits wide and/or high its not worth it so fall back.

Subject: [PATCH 14/15] gma500: nuke the PSB debug stuff

From: Alan Cox <[email protected]>

Lose all the PSB debug gunge. We can replace it with dev_dbg() like normal
drivers if and when we need debug on stuff.

Linux has perfectly good printing functions and using them means we can
use dev_dbg() which supports things like nice runtime switching.

You mean like the drm debug functions runtime switching? that predated
the kernel ones and nobody ever ported :-)

Though if psb wants to be different to other drm drivers it can lead the
way, though it'll be a total nightmare for all the people who follow
documentation on how to debug drm drivers using drm.debug=1,2,4,8. for
various code paths.

Yes, my concern was about drm.debug and use of all the DRM portability stuff
(like using DRM_IRQ_HANDLED instead of IRQ_HANDLED, etc...)

The portability might not be important at this point but I just wanted to raise
the question so I know what is right / wrong.

Alan, I've been working on the output code but think I've reached a dead end.
I'm up to 20000 lines of changes and it's just a big mess. I'm gonna go for
slowly fixing up the current code instead. I also got my hands on a laptop
with a gma500 so I can test that my changes doesn't break LVDS. Stay tuned.

Thanks

Actually it seems to work out nicely because you can debug DRM core
goings on and driver goings on separately. Also the driver ones can be
turned on/off on their own at runtime which is a godsend.

As you can imagine I've been testing the debugging a fair bit !

The gma500 driver uses a lot of direct Linux services rather than
disappearing into the weird world of drm_mm and the like so any
portability is going to be a bit of an illusion at best.

If someone ports it to another GPL licensed OS then I may have to
reconsider a bit, we shall see.

Will do. Got another chunk of patches to fire at Greg shortly and I've
now beaten pretty much all of it into passing CodingStyle so hopefully
any noise will settle down at that point.

Still not ready to leave staging, passing CodingStyle and being clean are
not quite the same thing in this case !

Given that I've mucked around in drm_mm quite a bit I'd be very interested
in your opinion about what's weird in it (and presumably what could be
improved). Can you elaborate?

Thanks a lot, Daniel

Mostly the API, which is also somewhat poorly documented. I've not dug
into the internals beyond trying to figure out how to use it. Looking at
the users the API is non-obvious, the interface involves a mix of calls
and digging deep into struct internals.

I'd have expected an API that had allocate/free type methods and exposed
the needed information directly or very easily not one that has drivers
doing. drm_sman seems to be attempt in that direction but its also rather
odd with interfaces like


item = drm_sman_alloc(&dev_priv->sman, mem->type, tmpSize, 0,
(unsigned long)file_priv);
mutex_unlock(&dev->struct_mutex);
if (item) {
mem->offset = ((mem->type == VIA_MEM_VIDEO) ?
dev_priv->vram_offset :
dev_priv->agp_offset) + (item->mm->
offset(item->mm, item->mm_info) <<
VIA_MM_ALIGN_SHIFT); mem->index = item->user_hash.key;


where the item->... gymnastics are spectacular to say the least given the
basic function of the allocator appears to be to provide said offset in
the first place.

And ultimately this is why I went with using allocate_region and friends
plus using GEM to do handles, which was a good choice for other reasons
as GEM is rather nicely designed barring the lack of a couple of helpers
and the few lines needed to split the shmem/handle abstraction properly.

Possibly drm_sman and friends should just wrap whatever simple native
allocator exists on the OS ?

Well, I've rewritten the api but that transition is not yet complete, i.e.
the new interface is there, but no driver is converted yet. The old api
has a two-step allocation (search_free + get_block) and frees allocated
ranges with put_block. The new api has just insert_node and remove_node,
struct drm_mm_node must be allocated by the caller (to get rid of the racy
preallocation scheme and allow embedding of drm_mm_node).

There's also the lru scanning helpers (only used by intel). Under specific
conditions (should be all documented in comments) this can be used as an
eviction roaster.

Generally only node->start should be used by drivers, otherwise
drm_mm_node should be opaque. At least that's the idea.

btw, old conversion patches for i915 to the new interface are at:

http://cgit.freedesktop.org/~danvet/drm/log/?h=embed-gtt-space

When creating the new interfaces I've tried to document them. Ideas to
improve that highly welcome.

Should be fixed, see above ;-)

Well, drm_mm has some graphics specific magic (range restricted scans and
the eviction helpers). But simpler stuff like sman is imo just "drm likes
to reinvent the wheel". Unfortunately I don't have the hw, so I haven't
dared to touch it (the snippet you've posted is a prime example why).

Yours, Daniel
