Ville Syrjälä authored
When moving the pipe disable & co. function calls from haswell_crtc_disable() into the encoder .post_disable() hooks I neglected to account for the MST vs. DDI interactions properly. This now leads us to call these functions two times for the last MST stream (once from the MST code and a second time from the DDI code). The calls from the DDI code should only be done for SST and not MST. Add the proper check for that. This results in an MCE on ICL. My vague theory is that we turn off the transcoder clock from the MST code and then we proceed to touch something in the DDI code which still depends on that clock causing the hardware to become upset. Though I can't really explain why Stan's hack of omitting the pipe disable in the MST code would avoid the MCE since we should still be turning off the transcoder clock. But maybe there's something magic in the hw that keeps the clock on as long as the pipe is on. Or maybe the clock isn't the problem and we now touch something in the DDI disable code that really does need the pipe to be still enabled. v2: Rebase to latest drm-tip Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Manasi Navare <manasi.d.navare@intel.com> Reported-by:

While this is encroaching on midlayer territory, having already made the state allocation a previous step in pinning, we can now pull the common intel_context_active_acquire() into intel_context_pin() itself. This is a prelude to make the activation a separate step inside pinning, outside of the ce->pin_mutex Signed-off-by:

Since we now allow the intel_context_unpin() to run unserialised, we risk our operations under the intel_context_lock_pinned() being run as the context is unpinned (and thus invalidating our state). We can atomically acquire the pin, testing to see if it is pinned in the process, thus ensuring that the state remains consistent during the course of the whole operation.

Access through the GGTT (iomap) into the vma does require the device to be awake. However, we often take the i915_vma_pin_iomap() as an early preparatory step that is long before we use the iomap. Asserting that the device is awake at pin time does not protect us, and is merely a nuisance. Signed-off-by:

Recent improvements in the state tracking in i915 caused PSR to not be enabled when reusing firmware/BIOS modeset, this is due to all initial commits returning ealier in intel_atomic_check() as needs_modeset() is always false. To fix that here forcing the state compute phase in CRTC that is driving the eDP that supports PSR once. Enable or disable PSR do not require a fullmodeset, so user will still experience glitch free boot process plus the power savings that PSR brings. It was tried to set mode_changed in intel_initial_commit() but at this point the connectors are not registered causing a crash when computing encoder state. v2: - removed function return - change arguments to match intel_hdcp_atomic_check v3: - replaced drm includes in intel_psr.h by forward declaration(Jani) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=112253 Reported-by: <s.zharkoff@gmail.com> Cc: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by:

Imre Deak authored
Currently the GGTT offset of a UV plane in a semiplanar YUV FB is tile size (4kB) aligned. I noticed, that enforcing only this alignment leads oddly to random memory corruptions on TGL while scanning out Y-tiled FBs. This issue can be easily reproduced with a UV plane offset that is not aligned to the plane's tile row size. Some experiments showed the correct alignment to be tile row size indeed. This also makes sense, since the de-tiling fence created for the object - with its own stride and so "left" and "right" edge - applies to all the planes in the FB, so each tile row of all planes should be tile row aligned. In fact BSpec requires this alignment since SKL. On SKL we may enforce this due to the AUX plane x,y coords check, but on ICL and TGL we don't. For now enforce this only on TGL; I can follow up with any necessary change for ICL after more tests. BSpec requires a stricter alignment for linear UV planes too (kind of a tile row alignment), but it's unclear whether that's really needed (couldn't be explained with the de-tiling fence as above) and enforcing that could break existing user space; so avoid that too for now until more tests. v2: - Clarify the commit log wrt. the address space the alignment applies to.

At least one framebuffer plane on TGL - the UV plane of YUV semiplanar FBs - requires a non-power-of-2 alignment, so add support for this. This new alignment restriction applies only to an offset within an FB, so the GEM buffer itself containing the FB must still be power-of-2 aligned. Add a check for this (in practice plane 0, since the plane 0 offset must be 0). v2: - Fix WARN check for alignment=0. v3: - Return error for alignment programming bugs.

For hardware that does not interpret the startadd field correctly, add the module parameter 'hw_bug_no_startadd', which enables the workaround. v3: * style and typo fixes v2: * ask user for feedback if the option is active Signed-off-by:

Drivers that what to allocate VRAM GEM objects with additional fields can now do this by implementing struct drm_driver.gem_create_object. v3: * separately check allocation failure in if/else branches before upcast to gbo v2: * only cast to gbo within if branch; set gbo directly in else branch Signed-off-by:

TTM is an implementation detail of the VRAM helpers and therefore shouldn't be exposed to the callers. There's only one correct value for the BO device anyway, which is the one stored in the DRM device. So remove struct ttm_bo_device from the VRAM-helper interface and use the device's VRAM manager unconditionally. The GEM initializer function fails if the VRAM manager has not been initialized.
