Re: Broken vblanks on Intel

  The Intel driver continues to call modeset before installing the irq
  handler.  I discussed this issue several months ago, but have only
  recently become painfully aware of the deeper issues.  Things seem to
  work ok, when you first start X, due to the fact that nothing is
  actually waiting on vblanks before the handler gets installed.
  During a Vt switch however, what I found was that with gears running
  synced to vblank while switching, pre-modeset says that vblanks are
  on and enables the pipestat registers.  post-modeset schedules them
  to be disabled at some point in the future.  At this point,
  vblank_enabled = 1.  Now, the interrupt handler gets installed, in
  preinstall it wipes out both pipestat registers and again in
  postinstall, clearing status bits this time.  That means that
  vblank_enabled is 1 and pipestat is empty.  As long as there is a
  consumer asking for vblank, vblank_disable_fn never fires to clean
  all of this mess up.  vblank_get won't ever actually turn vblanks
  back on, because it thinks they are already on.  So the client just
  hangs there.
  
  I think that all of the libdrm code to deal with clients stalling on
  vblank was probably not needed.  What happens now, is that while you
  are switched away or in dpms sleep, the client requesting vblank just
  repeatedly fires the timeout, rather than just stalling until you come
  back and seeing that the vblank counter has jumped way ahead of it and
  going on.  As it is now, it continues to render one frame / sec while
  it is offscreen.
 
 Yeah that does look like a real problem...  Can we check whether the
 handler has been installed at modeset time instead though?  E.g.
 (totally untested):
 
 diff --git a/drivers/gpu/drm/drm_irq.c b/drivers/gpu/drm/drm_irq.c
 index 93e677a..f2e4e1c 100644
 --- a/drivers/gpu/drm/drm_irq.c
 +++ b/drivers/gpu/drm/drm_irq.c
 @@ -504,7 +504,7 @@ int drm_modeset_ctl(struct drm_device *dev, void
 *data, int crtc, ret = 0;
 
 /* If drm_vblank_init() hasn't been called yet, just no-op */
 -   if (!dev-num_crtcs)
 +   if (!dev-num_crtcs || !dev-irq_enabled)
 goto out;
 
 crtc = modeset-crtc;

I think that means that you won't take a reference of the hardware
vblank counter over vt switch.

 Unfortunately, the rules keep changing here.  When we first pushed this
 stuff we were assuming that interrupts  vblanks would be enabled at
 load time and stay on forever.  But now we have vblank init at load
 time, but interrupts going on  off at VT switch and startup time... it
 really messes up the logic.

This is basically what I am doing now...  I have re-worked all the
interrupt code to install/uninstall the handler on FreeBSD at
load/unload time.  The drm_irq_(un)install() ioctls just (un)mask stuff.
Fixing the ddx still seems like the right plan though.  The radeon
driver seems to handle this correctly... It also doesn't try to disable
interrupts over vt switch, which seems to work well.

This happens with mesa 7.4 as well (which I use, as you can see from the

Intel(r) G45 Programmer's Reference Manual

RE:

Intel® G45 Programmer’s Reference Manual

  _

We are pleased to announce that the Intel® G45 Express Chipset
[Graphics and Memory Controller Hub-GMCH] Programmer’s Reference Manual
(PRM) is now publicly available!  The PRM resides on the Linux Graphics
website (http://intellinuxgraphics.org/index.html) as well as the Visual
Computing Training website (http://moss.amr.ith.intel.com/sites/VCG/VCG%
20Training/default.aspx).



The PRM describes the architectural behavior and programming
environment of the chipset and graphics devices.  The GMCH’s Graphics
Controller (GC) contains an extensive set of registers and instructions
for configuration, 2D, 3D, and Video systems. The PRM describes the
register, instruction, and memory interfaces and the device behaviors as
controlled and observed through those interfaces.  The PRM also
describes the registers and instructions and provides detailed bit/field
descriptions.  This information is critical to the development and
maintenance of Intel graphics drivers for this hardware.



Many thanks to the Graphics Engineering team and the Open Source
Technology Center for their work in identifying the appropriate material
to include in the PRM.  We would like to recognize Patricia Langstraat
for her technical writing prowess as well as Eric Anholt for his help in
reviewing the draft PRM material.  Others on Jeff Bock’s team were
invaluable in their efforts to ensure this PRM contains useful
information for the open source community.

Under a non-SMP kernel (the machine on which I run only has one core anyway,
it's a Celeron M 530) it doesn't seem to crash the kernel - but I can't
guarantee that was the only thing to change.

However I managed to capture the relevant Xorg crash (that possibly triggered,
or at least was closely related, to this kernel crash) backtrace, if it helps
at all to debug this. I reported it in the Debian BTS at 

   http://bugs.debian.org/524287

.

I'm still working to get a good backtrace on the kernel crash, I guess I'll
have to compile a SMP kernel for that and see if SMP makes this happen...

I'd suggest not to include those patches even if they would fix the issue. They
are pretty invasive, touch sensitive area (incorrect RS setup can easily lockup
GPU) and weren't tested separately that much (but the whole patch-set from
2009-03-06 has been tested thoroughly on r300, r400 and r500 cards by Markus
Amsler and on rs690 by me).
Also d8b8fb68954e6eebd0b38708c25a5bec4cf1a26c patch depends on

Intel(r) G45 Programmer's Reference Manual

RE:

Intel(r) G45 Programmer's Reference Manual



We are pleased to announce that the Intel(r) G45 Express Chipset [Graphics and 
Memory Controller Hub-GMCH] Programmer's Reference Manual (PRM) is now publicly 
available!  The PRM resides on the Linux Graphics website 
(http://intellinuxgraphics.org/index.html) as well as the Visual Computing 
Training website 
(http://moss.amr.ith.intel.com/sites/VCG/VCG%20Training/default.aspx).

The PRM describes the architectural behavior and programming environment of the 
chipset and graphics devices.  The GMCH's Graphics Controller (GC) contains an 
extensive set of registers and instructions for configuration, 2D, 3D, and 
Video systems. The PRM describes the register, instruction, and memory 
interfaces and the device behaviors as controlled and observed through those 
interfaces.  The PRM also describes the registers and instructions and provides 
detailed bit/field descriptions.  This information is critical to the 
development and maintenance of Intel graphics drivers for this hardware.

Many thanks to the Graphics Engineering team and the Open Source Technology 
Center for their work in identifying the appropriate material to include in the 
PRM.  We would like to recognize Patricia Langstraat for her technical writing 
prowess as well as Eric Anholt for his help in reviewing the draft PRM 
material.  Others on Jeff Bock's team were invaluable in their efforts to 
ensure this PRM contains useful information for the open source community.
