Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ...

2013-10-30drm: allow DRM_IOCTL_VERSION on render-nodesDavid Herrmann1-1/+1
DRM_IOCTL_VERSION is a reliable way to get the driver-name and version information. It's not related to the interface-version (SET_VERSION ioctl) so we can safely enable it on render-nodes. Note that gbm uses udev-BUSID to load the correct mesa driver. However, the VERSION ioctl should be the more reliable way to do this (in case we add new DRM-bus drivers which have no BUSID or similar).

2013-10-29drm/i915: Fix the PPT fdi lane bifurcate state handling on ivbDaniel Vetter1-47/+48
Originally I've thought that this is leftover hw state dirt from the BIOS. But after way too much helpless flailing around on my part I've noticed that the actual bug is when we change the state of an already active pipe. For example when we change the fdi lines from 2 to 3 without switching off outputs in-between we'll never see the crucial on->off transition in the ->modeset_global_resources hook the current logic relies on. Patch version 2 got this right by instead also checking whether the pipe is indeed active. But that in turn broke things when pipes have been turned off through dpms since the bifurcate enabling is done in the ->crtc_mode_set callback. To address this issues discussed with Ville in the patch review move the setting of the bifurcate bit into the ->crtc_enable hook. That way we won't wreak havoc with this state when userspace puts all other outputs into dpms off state. This also moves us forward with our overall goal to unify the modeset and dpms on paths (which we need to have to allow runtime pm in the dpms off state). Unfortunately this requires us to move the bifurcate helpers around a bit. Also update the commit message, I've misanalyzed the bug rather badly.

2013-10-28drm/i915/dp: workaround BIOS eDP bpp clamping issueJani Nikula1-0/+20
This isn't a real fix to the problem, but rather a stopgap measure while trying to find a proper solution. There are several laptops out there that fail to light up the eDP panel in UEFI boot mode. They seem to be mostly IVB machines, including but apparently not limited to Dell XPS 13, Asus TX300, Asus UX31A, Asus UX32VD, Acer Aspire S7. They seem to work in CSM or legacy boot. The difference between UEFI and CSM is that the BIOS provides a different VBT to the kernel. The UEFI VBT typically specifies 18 bpp and 1.62 GHz link for eDP, while CSM VBT has 24 bpp and 2.7 GHz link. We end up clamping to 18 bpp in UEFI mode, which we can fit in the 1.62 Ghz link, and for reasons yet unknown fail to light up the panel. Dithering from 24 to 18 bpp itself seems to work; if we use 18 bpp with 2.7 GHz link, the eDP panel lights up. So essentially this is a link speed issue, and *not* a bpp clamping issue. The bug raised its head since commit 657445fe8660100ad174600ebfa61536392b7624 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sat May 4 10:09:18 2013 +0200 Revert "drm/i915: revert eDP bpp clamping code changes" which started clamping bpp *before* computing the link requirements, and thus affecting the required bandwidth. Clamping after the computations kept the link at 2.7 GHz. Even though the BIOS tells us to use 18 bpp through the VBT, it happily boots up at 24 bpp and 2.7 GHz itself! Use this information to selectively ignore the VBT provided value. We can't ignore the VBT eDP bpp altogether, as there are other laptops that do require the clamping to be used due to EDID reporting higher bpp than the panel can support.

2013-10-18drm/i915: Disable GGTT PTEs on GEN6+ suspendBen Widawsky4-12/+78
Once the machine gets to a certain point in the suspend process, we expect the GPU to be idle. If it is not, we might corrupt memory. Empirically (with an early version of this patch) we have seen this is not the case. We cannot currently explain why the latent GPU writes occur. In the technical sense, this patch is a workaround in that we have an issue we can't explain, and the patch indirectly solves the issue. However, it's really better than a workaround because we understand why it works, and it really should be a safe thing to do in all cases. The noticeable effect other than the debug messages would be an increase in the suspend time. I have not measure how expensive it actually is. I think it would be good to spend further time to root cause why we're seeing these latent writes, but it shouldn't preclude preventing the fallout. NOTE: It should be safe (and makes some sense IMO) to also keep the VALID bit unset on resume when we clear_range(). I've opted not to do this as properly clearing those bits at some later point would be extra work. v2: Fix bugzilla link Bugzilla: http://bugs.freedesktop.org/show_bug.cgi?id=65496 Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=59321 Tested-by: Takashi Iwai <tiwai@suse.de> Tested-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Tested-By: Todd Previte <tprevite@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2013-10-11Revert "i915: Update VGA arbiter support for newer devices"Dave Airlie2-31/+3
This reverts commit 81b5c7bc8de3e6f63419139c2fc91bf81dea8a7d. Adding drm/i915 into the vga arbiter chain means that X (in a piece of well-meant paranoia) will do a get/put on the vga decoding around _every_ accel call down into the ddx. Which results in some nice performance disasters [1]. This really breaks userspace, by disabling DRI for everyone, and stops OpenGL from working, this isn't limited to just the i915 but both the integrated and discrete GPUs on multi-gpu systems, in other words this causes untold worlds of pain, Ville tried to come up with a Great Hack to fiddle the required VGA I/O ops behind everyone's back using stop_machine, but that didn't really work out [2]. Given that we're fairly late in the -rc stage for such games let's just revert this all. One thing we might want to keep is to delay the disabling of the vga decoding until the fbdev emulation and the fbcon screen is set up. If we kill vga mem decoding beforehand fbcon can end up with a white square in the top-left corner it tried to save from the vga memory for a seamless transition. And we have bug reports on older platforms which seem to match these symptoms. But again that's something to play around with in -next.
