(you might need to add forward declaration like struct radeon; at top of radeon_asic.h no biggy thought). I disagree. It's not quite there yet, but when all the asic specific stuff is gathered in radeon_asic.h (like I've done for r100 in my last patch), radeon_asic.h is the private header for asic stuff. And radeon.h is the public interface for radeon_asic. Then adding #include radeon_asic.h in random places would serve as a warning sign that there's likely a layering violation ahead. After all, generic code should not muck around in the asic private stuff. Unconditionally including radeon_asic.h therefore runs counter to the bigger idea behind my patches.

[PATCH 2/3] libdrm_radeon: Optimize cs_gem_reloc to do less looping. (V2)
bo-referenced_in_cs is checked if bo is already in cs. Adding and removing
reference in bo is done with atomic operations to allow parallel access to a
bo from multiple contexts.
cs-id generation code quarentees there is not duplicated ids which limits
number of cs-ids to 32. If there is more cs objects rest will get id 0.
V2:
- Fix configure to check for atomics operations if libdrm_radeon is selected
and libdrm_intel is not.
- Make atomic operations private to libdrm_radeon.
- Add warning messages if disabling automaticaly selected libdrm_(radeon|intel)
This optimization decreases cs_write_reloc share of torcs profiling from 4.3%
to 2.6%.

So physical addresses for DMA programming needs to use the MFN. Xen transparently does the correct translation using the _PAGE_IOMEM prot-bit in the PTE. If the bit is set, then Xen assumes that the backing memory is in the IOMEM space, and PFN equals MFN. If not set, page_to_pfn() returns MFN. The patch enables the ttm_bo_vm_fault() handler to behave correctly under Xen, and has no side-effects on normal (not under Xen) operations. The use of TTM_PL_FLAG_TT in the check assumes that all other placements are backed by device memory or IO. If there are any other placements that use system memory, that flag has to be OR'ed into the check. The above patch has no implications on a normal kernel or a Xen pv_ops kernel booted without the Xen hypervisor. My testing is on a debian-lenny environment on a Core2 processor with nVidia GeForce 9400 GT. Efficacy of patch: successful flightgear run on dom0 AND bareboot!

I don't think this is the best strategy. Having the headers under
_SOURCES already means they'll get distributed. The only reason for
the separate _HEADERS declarations is if you need to install them.

What do you think the average user will care about more? * Seeing kernel oops/panic output about once in a lifetime. * Being able to start/use X in the first place and enabling it to use all of VRAM. Personally, I've never even seen any kernel oops/panic output despite numerous opportunities for that in the couple of months I've been using KMS. But I have spent considerable time and effort trying to get rid of the pinned fbcon BO. If the oops/panic output is the only thing preventing that, maybe that should only be enabled via some module option for developers. I'm all for it! I'm looking into the details for this. It will require some changes to internal apis to make it to work. Can't it print the oops on whatever is currently displayed? It need not be a dedicated buffer as long as there is always some buffer. But perhaps this is more complex than that. Yes it is very complex. Reading the code and drm specs you come to realize buffer handling is done with GEM, TTM, or for older drivers drm_maps. Drivers often handle a combine of those, meaning no real wrapper from one api to another :-( From the code it appears GEM is the main userland interface when using KMS. Some how TTM is also usable from userland but I never found a clear example of how that is done. So to the average userland app writer it is a mystery. As for hardware that has a static front buffer I can see how to use drm_maps or TTM but I don't see a easy way to map it to the GEM api. Also their exist ioctl for gem but it appears no one actually uses them but instead write their own :-( So you can see the confusion here. Outside of what I described above the drm_framebuffer handling is a mess. From what I can see with the code you can only create a drm_framebuffer with the GEM api. With this case the two most important functions to provide are dev-mode_config.funcs-fb_create(dev, file_priv, r) and fb-funcs-create_handle(fb, file_priv, r-handle); As you can see if the functions they depend on a handle and a drm_file. To make it possible to create a framebuffer internally using a common code we would remove those requirements. This gets me to point of where to go from here. We have two choices. The first being we could just make the drm_framebuffer code totally gem dependent thus we could cleanup the drivers code up by moving gem code there. The second option is to make the drm_framebuffer code agnostic to the gem layer. So I have been pondering on how to make the second option work. There is one thing that all these layers do share in common. That is they have some sort of drm_hash with a object lookup. Still pondering how that would be done.-- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

ok - turned out that the oops where pm related. When started with
radeon.{dynpm,dynclks}=0 everything works fine!
Unfortunately, I cannot test the GPU reset patches alone, as they do not apply
to 2.6.33. Jérôme, could you please supply something relative to 2.6.33?
Thanks!

Re: [Linux-fbdev-devel] drm_fb_helper: Impossible to change video mode
It would be nice to find a way to reclaim the console memory for X, but I'm not sure that can be done and still provide a good way to provide oops support. What do you think the average user will care about more? * Seeing kernel oops/panic output about once in a lifetime. * Being able to start/use X in the first place and enabling it to use all of VRAM. Personally, I've never even seen any kernel oops/panic output despite numerous opportunities for that in the couple of months I've been using KMS. But I have spent considerable time and effort trying to get rid of the pinned fbcon BO. If the oops/panic output is the only thing preventing that, maybe that should only be enabled via some module option for developers. I'm all for it! I'm looking into the details for this. It will require some changes to internal apis to make it to work. Can't it print the oops on whatever is currently displayed? It need not be a dedicated buffer as long as there is always some buffer. But perhaps this is more complex than that. Yes it is very complex. Reading the code and drm specs you come to realize buffer handling is done with GEM, TTM, or for older drivers drm_maps. Drivers often handle a combine of those, meaning no real wrapper from one api to another :-( From the code it appears GEM is the main userland interface when using KMS. Some how TTM is also usable from userland but I never found a clear example of how that is done. So to the average userland app writer it is a mystery. As for hardware that has a static front buffer I can see how to use drm_maps or TTM but I don't see a easy way to map it to the GEM api. Also their exist ioctl for gem but it appears no one actually uses them but instead write their own :-( So you can see the confusion here. Userspace buffer management interfaces are pre-driver, the only requirement if that they have a 32-bit handle to identify buffers uniquely. Pre-KMS drivers don't exist for the purposes of fb interaction, so drm_maps are ignorable from that pov. Outside of what I described above the drm_framebuffer handling is a mess. From what I can see with the code you can only create a drm_framebuffer with the GEM api. With this case the two most important functions to provide are This isn't correct. You get a drm_file and a handle, the driver then uses these to do whatever it wants to do. This means lookup a GEM object or whatever but there is no reliance on GEM or any other memory manager outside the driver. Again a handle a file priv are in no way GEM specific. dev-mode_config.funcs-fb_create(dev, file_priv, r) and fb-funcs-create_handle(fb, file_priv, r-handle); As you can see if the functions they depend on a handle and a drm_file. To make it possible to create a framebuffer internally using a common code we would remove those requirements. We already have an internal framebuffer creation for fbdev, there is an fb_create callback that does this, its not up to dynamic fbdev creation. This gets me to point of where to go from here. We have two choices. The first being we could just make the drm_framebuffer code totally gem dependent thus we could cleanup the drivers code up by moving gem code there. The second option is to make the drm_framebuffer code agnostic to the gem layer. So I have been pondering on how to make the second option work. There is one thing that all these layers do share in common. That is they have some sort of drm_hash with a object lookup. Still pondering how that would be done. I'm not sure either of these makes sense, can you clearly state the goal and maybe we can work out what you need.
