2016-06-13drm/radeon: fix asic initialization for virtualized environmentsAlex Deucher
When executing in a PCI passthrough based virtuzliation environment, the hypervisor will usually attempt to send a PCIe bus reset signal to the ASIC when the VM reboots. In this scenario, the card is not correctly initialized, but we still consider it to be posted. Therefore, in a passthrough based environemnt we should always post the card to guarantee it is in a good state for driver initialization.

When executing in a PCI passthrough based virtuzliation environemnt, the hypervisor will usually attempt to send a PCIe bus reset signal to the ASIC when the VM reboots. In this scenario, the card is not correctly initialized, but we still consider it to be posted. Therefore, in a passthrough based environemnt we should always post the card to guarantee it is in a good state for driver initialization. However, if we are operating in SR-IOV mode it is up to the GIM driver to manage the asic state, therefore we should not post the card (and shouldn't be able to do it either). v2: add missing semi-colon Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Andres Rodriguez <andres.rodriguez@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2016-06-13drm/radeon: do not hard reset GPU while freezing on r600/r700 familyJérôme Glisse
Seems r600/r700 does not like hard reset while freezing for hibernation (regression due to 274ad65c9d02bdcbee9bae045517864c3521d530 which itself is a fix for hibernation on some GPU families). Until i can debug further issue with r600, let just disable this for r600/r700 as they are very similar family and bug affecting one likely affect the other.

2016-06-10drm/i915: Extract physical display dimensions from VBTVille Syrjälä
The VBT has these mysterious H/V image sizes as part of the display timings. Looking at some dumps those appear to be the physical dimensions in mm. Which makes sense since the timing descriptor matches the format used by EDID detailed timing descriptor, which defines these as "H/V Addressable Video Image Size in mm". So let's use that information from the panel fixed mode to get the physical dimensions for LVDS/eDP/DSI displays. And with that we can fill out the display_info so that userspace can get at it via GetConnector. v2: Use (hi<<8)|lo instead of broken (hi<<4)+lo Handle LVDS and eDP too Cc: Stephen Just <stephenjust@gmail.com> Tested-by: Stephen Just <stephenjust@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=96255 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1464685714-30507-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Mika Kahola <mika.kahola@intel.com> (cherry picked from commit df457245b5b7515cf97763ebd8975229e34d4cf3) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2016-06-10drm/i915: Check VBT for port presence in addition to the strap on VLV/CHVVille Syrjälä
Apparently some CHV boards failed to hook up the port presence straps for HDMI ports as well (earlier we assumed this problem only affected eDP ports). So let's check the VBT in addition to the strap, and if either one claims that the port is present go ahead and register the relevant connector. While at it, change port D to register DP before HDMI as we do for ports B and C since commit 457c52d87e5d ("drm/i915: Only ignore eDP ports that are connected") Also print a debug message when we register a HDMI connector to aid in diagnosing missing/incorrect ports.

2016-06-10drm/i915: Only ignore eDP ports that are connectedChris Wilson
If the VBT says that a certain port should be eDP (and hence fused off from HDMI), but in reality it isn't, we need to try and acquire the HDMI connection instead. So only trust the VBT edp setting if we can connect to an eDP device on that port.

My old 845g complains that the child_device_size inside its VBT, version 110, is incorrect. Let's fiddle with the version matching such that it works with this VBT (i.e. treat BIOS v110 as having the same size as v108).

2016-06-08drm/fsl-dcu: use flat regmap cacheStefan Agner
Using flat regmap cache instead of RB-tree to avoid the following lockdep warning on driver load: WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2755 lockdep_trace_alloc+0x15c/0x160() DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags)) The RB-tree regmap cache needs to allocate new space on first writes. However, allocations in an atomic context (e.g. when a spinlock is held) are not allowed. The function regmap_write calls map->lock, which acquires a spinlock in the fast_io case. Since the FSL DCU driver uses MMIO, the regmap bus of type regmap_mmio is being used which has fast_io set to true. Use flat regmap cache and specify max register to be large enouth to cover all registers available in LS1021a and Vybrids register space.

2016-06-08objtool, drm/vmwgfx: Fix "duplicate frame pointer save" warningJosh Poimboeuf
objtool reports the following warnings: drivers/gpu/drm/vmwgfx/vmwgfx_msg.o: warning: objtool: vmw_send_msg()+0x107: duplicate frame pointer save drivers/gpu/drm/vmwgfx/vmwgfx_msg.o: warning: objtool: vmw_host_get_guestinfo()+0x252: duplicate frame pointer save To quote Linus: "The reason is that VMW_PORT_HB_OUT() uses a magic instruction sequence (a "rep outsb") to communicate with the hypervisor (it's a virtual GPU driver for vmware), and %rbp is part of the communication. So the inline asm does a save-and-restore of the frame pointer around the instruction sequence. I actually find the objtool warning to be quite reasonable, so it's not exactly a false positive, since in this case it actually does point out that the frame pointer won't be reliable over that instruction sequence. But in this particular case it just ends up being the wrong thing - the code is what it is, and %rbp just can't have the frame information due to annoying magic calling conventions." Silence the warnings by telling objtool to ignore the two functions which use the VMW_PORT_HB_{IN,OUT} macros.

2016-06-07drm/nouveau/disp/sor/gf119: both links use the same training registerBen Skeggs
It appears that, for whatever reason, both link A and B use the same register to control the training pattern. It's a little odd, as the GPUs before this (Tesla/Fermi1) have per-link registers, as do newer GPUs (Maxwell). Fixes the third DP output on NVS 510 (GK107).
