We need two special things to properly wire this up: - Add another argument to gmbus_wait_hw_status to pass in the correct interrupt bit in gmbus4. - Since we can only get an irq for one of the two events we want, hand-roll the wait_event_timeout code so that we wake up every jiffie and can check for NAKs. This way we also subsume gmbus support for platforms without interrupts (or where those are not yet enabled). The important bit really is to only enable one gmbus interrupt source at the same time - with that piece of lore figured out, this seems to work flawlessly. Ben Widawsky rightfully complained the lack of measurements for the claimed benefits (especially since the first version was actually broken and fell back to bit-banging). Previously reading the 256 byte hdmi EDID takes about 72 ms here. With this patch it's down to 33 ms. Given that transfering the 256 bytes over i2c at wire speed takes 20.5ms alone, the reduction in additional overhead is rather nice. v2: Chris Wilson wondered whether GMBUS4 might contain some set bits when booting up an hence result in some spurious interrupts. Since we clear GMBUS4 after every wait and we do gmbus transfer really early in the setup sequence to detect displays the window is small, but still be paranoid and clear it properly. v3: Clarify the comment that gmbus irq generation can only support one kind of event, why it bothers us and how we work around that limit.

Only enables the interrupt and puts a irq handler into place, doesn't do anything yet. Unfortunately there's no gmbus interrupt support for gen2/3 (safe for pnv, but there the irq is marked as "Test mode"). v2: Wire up the irq handler for vlv and gen4 properly. v3: i915_enable_pipestat expects the mask bit, not the status bits ... and for added hilarity those are rather inconsistently named.

The gmbus interrupt generation is rather fiddly: We can only ever enable one interrupt source (but we always want to check for NAK in addition to the real bit). And the bits in the gmbus status register don't map at all to the bis in the irq register. To prepare for this mess, start by extracting the hw status wait loop into it's own function, consolidate the NAK error handling a bit. To keep things flexible, pass in the status bit we care about (in addition to any NAK signalling). v2: I've failed to notice that the sense of GMBUS_ACTIVE is inverted, Chris Wilson gladly pointed that out for me. To keep things simple, ignore that case for now (we only need to idle the gmbus controller at the end of an entire i2c transaction, not after every message). Reviewed-by:

Otherwise the new&shiny irq-driven gmbus and dp aux code won't work that well. Noticed since the dp aux code doesn't have an automatic fallback with a timeout (since the hw provides for that already). v2: Simple move drm_irq_install before intel_modeset_gem_init, as suggested by Ben Widawsky. v3: Now that interrupts are enabled before all connectors are fully set up, we might fall over serving a HPD interrupt while things are still being set up. Instead of jumping through massive hoops and complicating the code with a separate hpd irq enable step, simply block out the hotplug work item from doing anything until things are in place. v4: Actually, we can enable hotplug processing only after the fbdev is fully set up, since we call down into the fbdev from the hotplug work functions. So stick the hpd enabling right next to the poll helper initialization. v5: We need to enable irqs before intel_modeset_init, since that function sets up the outputs. v6: Fixup cleanup sequence, too.

Simply use the last write-domain set for the object in the batch, trusting userspace to have correctly flushed the caches between usage as a write target. This check dates back from the golden age of having only a single operation per batch with the kernel repeating it for each cliprect, and conflicts both with userspace trying to efficiently batch multiple operations and with reducing the kernel overhead of relocation processing.

The primary purpose of this was to debug some use-after-free memory corruption that was causing an OOPS inside drm/i915. As it turned out the corruption was being caused elsewhere and i915.ko as a major user of many objects was being hit hardest. Indeed as we do frequent the generic kmalloc caches, dedicating one to ourselves (or at least naming one for us depending upon the core) aids debugging our own slab usage. Signed-off-by:

As FBC is commonly disabled due to limitations of the chipset upon output configurations, on many systems FBC is never enabled. For those systems, it is advantageous to make use of the stolen memory for other objects and so we defer allocation of the FBC chunk until we actually require it. This increases the likelihood of that allocation failing, but that in turns means that we are already taking advantage of the stolen memory! As well as delaying the allocation from driver initialisation until the first use of FBC, we also return the stolen block after we finish using it - allowing greater flexibility in our usage of stolen space. A side effect of this is that we can then attempt to allocate only the required amount of space (with a little slack to reduce reallocation rate and avoid fragmentation). Signed-off-by:

The routine to query the base of stolen memory was using the wrong registers and the wrong encodings on virtually every platform. It was not until the G33 refresh, that a PCI config register was introduced that explicitly said where the stolen memory was. Prior to 865G there was not even a register that said where the end of usable low memory was and where the stolen memory began (or ended depending upon chipset). Before then, one has to look at the BIOS memory maps to find the Top of Memory. Alas that is not exported by arch/x86 and so we have to resort to disabling stolen memory on gen2 for the time being. Then SandyBridge enlarged the PCI register to a full 32-bits and change the encoding of the address, so even though we happened to be querying the right register, we read the wrong bits and ended up using address 0 for our stolen data, i.e. notably FBC.

And use it whenever we call code that uses the DDIs. We already have intel_ddi.c and prefix every function with intel_ddi_something instead of haswell_something, so I think replacing the checks with HAS_DDI makes more sense. Just a cosmetical change, yes I know, but I have this OCD... Signed-off-by:

Since we drop dev->struct_mutex when going through the slowpath, the object might have been moved out of the cpu domain. Hence we need to clflush the entire object to ensure that after the ioctl returns, everything is coherent again (interwoven writes are ill-defined anyway). But we only need to do this if we start in the cpu domain and the object requires flushing for coherency. So don't do the flushing if the object is coherent anyway or if we've done in-line clfushing already. v2: i915_gem_clflush_object already checks whether the object is coherent and if so, drops the flushing. Hence we don't need to check that ourselves, simplifying the condition. v3: Reorder the checks for better clarity (and adjust the comment accordingly), suggested by Chris Wilson. Reviewed-by:

The shmem paths for pwrite/pread used a clever trick to hold onto a single page when dropping the big dev->struct_mutex for the slowpath. But this ran the risk of reinstating (or not completely purging) the backing storage when dropping purgeable objects. Hence the code needed to keep track of whether it ever dropped the lock, and if it did, manually check whether it needs to re-purge the backing storage. But thanks to the pages pin count introduced in commit a5570178 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Sep 4 21:02:54 2012 +0100 drm/i915: Pin backing pages whilst exporting through a dmabuf vmap which allowed us to pin the backing storage and remove that page reference trick from shmem_pwrite/read in commit f60d7f0c Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Sep 4 21:02:56 2012 +0100 drm/i915: Pin backing pages for pread and commit 755d2218 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Sep 4 21:02:55 2012 +0100 drm/i915: Pin backing pages for pwrite we can now abolish this check. The slowpath cleanup completely disappears from pread, and for pwrite we're only left with the domain fixup in case someone moved the object out of the cpu domain from under us. A follow-on patch will optimize that a notch more. Reviewed-by:

A few things needed to change: - HAS_PCH_SPLIT since ilk+ is not yet converted to this. - s/LVDS/intel_lvds->reg/ to prep for ilk conversion - replace the clock.p2 == 7 check with a is_dual_link check - s/adjusted_mode/intel_lvds->fixed_mode v2: Rebase on top of Jani Nikula's panel rework. I'm wondering whether we shouldn't add an attached_panel pointer to intel_encoder, to replace the encoder private ->attached_connector pointers, since that's essentially what we need. Reviewed-by:

Yeah, all users (both the clock selection special cases and the lvds pin pair stuff) are still in common code, but this will change. v2: Rebase on top of Jani Nikula's panel rework. v3: Incorporate review from Paulo Zanoni: - s/__is_dual_link_lvds/compute_is_dual_link_lvds - kill dev_priv->lvds_val - drop spurious whitespace change v4: Add a debug printk to display the dual-link status, as suggested by Paulo Zanoni in review.
