2015-11-06drm/vmwgfx: Properly flush cursor updates and page-flipsThomas Hellstrom2-1/+3
With the introduction of the new command buffer mechanism, proper care wasn't taken to flush cursor image updates and event-less screen-target page-flips. Fix this by introducing explicit flush points. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Brian Paul <brianp@vmware.com>
2015-11-06drm/i915/skl: disable display side power well support for nowImre Deak2-2/+21
The display power well support on this platform is in a somewhat broken state atm, so disable it by default. This in effect will get rid of incorrect assert WARNs about the CSR/DMC firmware not being loaded during power well toggling. It also removes a problem during driver loading where a register is accessed while its backing power well is down, resulting in another WARN. Until we come up with the root cause of the second problem and the proper fix for both issues, keep all display side power wells on. Also clarify a bit the option description.

2015-11-05drm/i915: Do graphics device reset under forcewakeMika Kuoppala1-1/+10
We have a timed release of a forcewake when using I915_READ/WRITE macros. wait_for() macro will go to quite long sleep if the first read doesn't satisfy the condition for successful exit. With these two interacting, it is possible that we lose the forcewake during the wait_for() and the subsequent read will reaquire forcewake. Further experiments with skl shows that when we lose forcewake, we lose the reset request we submitted. So reset request register is not power context saved. Grab forcewakes for all engines before starting the reset/request dance so that all requests stay valid for the duration of reset requisition across all the engines. v2: Add comment on power well sleeps. Wrap the reset handling under forcewake instead of just reset requests (Chris) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=92774 Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Tested-by: Tomi Sarvela <tomix.p.sarvela@intel.com> (v1, v2) Signed-off-by: Mika Kuoppala <mika.kuoppala@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1446721898-1450-1-git-send-email-mika.kuoppala@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2015-11-05drm/i915: Skip fence installation for objects with rotated views (v4)Vivek Kasireddy1-16/+20
While pinning a fb object to the display plane, only install a fence if the object is using a normal view. This corresponds with the behavior found in i915_gem_object_do_pin() where the fencability criteria is determined only for objects with normal views. v2: Look at the object's map_and_fenceable flag to determine whether to install a fence or not (Chris). v3: Pin and unpin a fence only if the current view type is normal. v4: Extend the "view type is normal" check for pin_fence as well.

2015-11-05vga_switcheroo: Drop client power state VGA_SWITCHEROO_INITLukas Wunner2-7/+0
hda_intel.c:azx_probe() defers initialization of an audio controller on the discrete GPU if the GPU is powered off. The power state of the GPU is determined by calling vga_switcheroo_get_client_state(). vga_switcheroo_get_client_state() returns VGA_SWITCHEROO_INIT if vga_switcheroo is not enabled, i.e. if no second GPU or no handler has registered. This can go wrong in the following scenario: - Driver for the integrated GPU is not loaded. - Driver for the discrete GPU registers with vga_switcheroo, uses driver power control to power down the GPU, handler cuts power to the GPU. - Driver for the audio controller gets loaded after the GPU was powered down, calls vga_switcheroo_get_client_state() which returns VGA_SWITCHEROO_INIT instead of VGA_SWITCHEROO_OFF. - Consequence: azx_probe() tries to initialize the audio controller even though the GPU is powered down. The power state VGA_SWITCHEROO_INIT was introduced by c8e9cf7bb240 ("vga_switcheroo: Add a helper function to get the client state"). It is not apparent what its benefit might be. The idea seems to be to initialize the audio controller even if the power state is VGA_SWITCHEROO_OFF (were vga_switcheroo enabled), but as shown above this can fail. Drop VGA_SWITCHEROO_INIT to solve this. Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Lukas Wunner <lukas@wunner.de> Signed-off-by: Dave Airlie <airlied@redhat.com>

2015-11-03drm/nouveau/pll/gk104: fix PLL instability due to bad configuration with gddr5Karol Herbst1-23/+77
This patch uses an approach closer to the nvidia driver to configure both PLLs for high gddr5 memory clocks (usually above 2400MHz) Previously nouveau used the one PLL as it was used for the lower clocks and just adjusted the second PLL to get as close as possible to the requested clock. This means for my card, that I got a 4050 MHz clock although 4008 MHz was requested. Now the driver iterates over a list of PLL configuration also used by the nvidia driver and then adjust the second PLL to get near the requested clock. Also it hold to some restriction I found while analyzing the PLL configurations This won't fix all gddr5 high clock issues itself, but it should be fine on hybrid gpu systems as found on many laptops these days. Also switching while normal desktop usage should be a lot more stable than before. v2: move the pll code into ramgk104 Signed-off-by: Karol Herbst <nouveau@karolherbst.de> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2015-11-03drm/nouveau/pci: Handle 5-bit and 8-bit tag fieldPierre Moreau6-0/+37
If the hardware supports extended tag field (8-bit ones), then enable it. This is usually done by the VBIOS, but not on some MBPs (see fdo#86537). In case extended tag field is not supported, 5-bit tag field is used which limits the possible number of requests to 32. Apparently bits 7:0 of 0x08841c stores some number of outstanding requests, so cap it to 32 if extended tag is unsupported. Fixes: fdo#86537 v2: Restrict changes to chipsets >= 0x84 v3: * Add nvkm_pci_mask to pci.h * Mask bit 8 before setting it v4: * Rename `add` argument of nvkm_pci_mask to `value` * Move code from nvkm_pci_init to g84_pci_init and remove PCIe and chipset checks v5: * Rebase code on latest PCI structure * Restore PCIe check * Fix namings in nvkm_pci_mask * Rephrase part of the commit message Signed-off-by: Pierre Moreau <pierre.morrow@free.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2015-11-03drm/nouveau/disp,pm: constify nvkm_object_func structuresJulia Lawall2-2/+2
These nvkm_object_func structures are never modified. All other nvkm_object_func structures are declared as const. Done with the help of Coccinelle. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2015-11-03drm/nouveau/gr: document mp error 0x10Ilia Mirkin1-0/+1
NVIDIA provided the documentation for mp error 0x10, INVALID_ADDR_SPACE, which apparently happens when trying to use an atomic operation on local or shared memory (instead of global memory). Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2015-11-03drm/nouveau: remove unused functionSudip Mukherjee2-15/+0
coverity.com reported that memset was using a buffer of size 0, on checking the code it turned out that the function was not being used. So remove it.

2015-11-03drm/nouveau/ibus/gf100: increase wait timeout to avoid read faultsSamuel Pitoiset6-4/+77
Increase clock timeout of some unknown engines in order to avoid failure at high gpcclk rate. This fixes IBUS read faults on my GF119 when reclocking is manually enabled. Note that memory reclocking is completely broken and NvMemExec has to be disabled to allow core clock reclocking only.
