Linux doesn't run on i386, anymore. See: commit d55c5a93 Author: H. Peter Anvin <hpa@linux.intel.com> Date: Wed Nov 28 11:50:24 2012 -0800 x86, 386 removal: Remove CONFIG_CMPXCHG All 486+ CPUs support CMPXCHG, so remove the fallback 386 support code. Furthermore, as the commit-message states, all 486+ CPUs support the CMPXCHG instruction and thus even legacy DRM can run fine. Drop the now superfluous "x86 == 3" check.

When I moved the irq disable down to after display disable, I didn't realise the gt suspend also required irqs off, so move it down as well. Fixes WARNs seen at suspend/resume time. v2: moved the rps flush down as well. Tested-by:

Regular randconfig nightly testing has detected problems with omapdrm. omapdrm fails to build when the kernel is built to support 64-bit DMA addresses and/or 64-bit physical addresses due to an assumption about the width of these types. Use %pad to print DMA addresses, rather than %x or %Zx (which is even more wrong than %x). Avoid passing a uint32_t pointer into a function which expects dma_addr_t pointer. drivers/gpu/drm/omapdrm/omap_plane.c: In function 'omap_plane_pre_apply': drivers/gpu/drm/omapdrm/omap_plane.c:145:2: error: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t' [-Werror=format] drivers/gpu/drm/omapdrm/omap_plane.c:145:2: error: format '%x' expects argument of type 'unsigned int', but argument 6 has type 'dma_addr_t' [-Werror=format] make[5]: *** [drivers/gpu/drm/omapdrm/omap_plane.o] Error 1 drivers/gpu/drm/omapdrm/omap_gem.c: In function 'omap_gem_get_paddr': drivers/gpu/drm/omapdrm/omap_gem.c:794:4: error: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'dma_addr_t' [-Werror=format] drivers/gpu/drm/omapdrm/omap_gem.c: In function 'omap_gem_describe': drivers/gpu/drm/omapdrm/omap_gem.c:991:4: error: format '%Zx' expects argument of type 'size_t', but argument 7 has type 'dma_addr_t' [-Werror=format] drivers/gpu/drm/omapdrm/omap_gem.c: In function 'omap_gem_init': drivers/gpu/drm/omapdrm/omap_gem.c:1470:4: error: format '%x' expects argument of type 'unsigned int', but argument 7 has type 'dma_addr_t' [-Werror=format] make[5]: *** [drivers/gpu/drm/omapdrm/omap_gem.o] Error 1 drivers/gpu/drm/omapdrm/omap_dmm_tiler.c: In function 'dmm_txn_append': drivers/gpu/drm/omapdrm/omap_dmm_tiler.c:226:2: error: passing argument 3 of 'alloc_dma' from incompatible pointer type [-Werror] make[5]: *** [drivers/gpu/drm/omapdrm/omap_dmm_tiler.o] Error 1 make[5]: Target `__build' not remade because of errors. make[4]: *** [drivers/gpu/drm/omapdrm] Error 2 Signed-off-by:

This adds DP 1.2 MST support on Haswell systems. Notes: a) this reworks irq handling for DP MST ports, so that we can avoid the mode config locking in the current hpd handlers, as we need to process up/down msgs at a better time. Changes since v0.1: use PORT_PCH_HOTPLUG to detect short vs long pulses add a workqueue to deal with digital events as they can get blocked on the main workqueue beyong mode_config mutex fix a bunch of modeset checker warnings acks irqs in the driver cleanup the MST encoders Changes since v0.2: check irq status again in work handler move around bring up and tear down to fix DPMS on/off use path properties. Changes since v0.3: updates for mst apis more state checker fixes irq handling improvements fbcon handling support improved reference counting of link - fixes redocking. Changes since v0.4: handle gpu reset hpd reinit without oopsing check link status on HPD irqs fix suspend/resume Changes since v0.5: use proper functions to get max link/lane counts fix another checker backtrace - due to connectors disappearing. set output type in more places fro, unknown->displayport don't talk to devices if no HPD asserted check mst on short irqs only check link status properly rebase onto prepping irq changes. drop unsued force_act Changes since v0.6: cleanup unused struct entry.

Not enough brown paper bags, you'll have to share one. (oops below). The initial match condition code was racy (locking is coming I hear). then along came: cd234b0b drm/i915: Do not dereference NULL crtc or fb until after checking Chris made an attempt to fix it, Ben "reviewed" it. Daniel merged it. Then drm/i915: Make use of intel_fb_obj() (v2) 2ff8fde1 made it worse by removing the obj check later. All in all, my laptop can't barely turn off the display without hitting this. Posted to #intel-gfx out of niceness, but I've merged this already into drm-next. Here's an oops.

Matt Roper authored
drm_plane_init() (the legacy plane initialization function) takes a bool as its final parameter; originally this indicated whether a plane was 'private' to the driver (before the DRM core understood non-overlay planes), now it indicates whether the plane is a primary plane (private planes were used by some drivers to represent primary planes internally). The newer drm_universal_plane_init() take an 'enum drm_plane_type' as its final parameter to allow the caller to specify the specific plane type desired (primary, cursor, or overlay). Due to a rebasing mistake, the primary plane helper is currently passing DRM_PLANE_TYPE_PRIMARY (enum value = 1) for drm_plane_init()'s boolean 'is_primary' parameter. This winds up giving the correct behavior since DRM_PLANE_TYPE_PRIMARY evaluates as true, but is confusing to anyone reading the code since we're passing an enum value (one of three possible values) for a boolean parameter. Replace the primary plane helper's call to drm_plane_init() with drm_universal_plane_init() so that the parameter and value types match up as expected. Signed-off-by:
