This patch doesn't have any functional change, but organize fruntbuffer invalidate and busy by removing unecesarry signature argument for ring. It was unsed on mark_fb_busy and only used on fb_obj_invalidate for the same ORIGIN_CS usage. So let's clean it a bit Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by:

We have enough generic hotplug functions sprinkled all over i915_irq.c to warrant moving them to a file of their own. This should further underline the distinction between generic code in the new file and platform specific hotplug and irq code that remains in i915_irq.c. Add new intel_hpd_init_work to keep work functions static, and rename get_port_from_pin to intel_hpd_pin_to_port while increasing its visibility, but keep everything else the same. Signed-off-by:

We'll have three functions: intel_hpd_irq_storm_detect for detecting irq storms, intel_hpd_irq_storm_disable for disabling hotplugs after detected storms, intel_hpd_irq_storm_reenable_work for re-enabling hotplug. No functional changes. Signed-off-by:

Continue abstracting hotplug storm related functions to clarify the code. This time, abstract hotplug irq storm related hotplug disabling. While at it, clean up the loop iterating over connectors for readability. Signed-off-by:
-
Jani Nikula authored
The hotplug work function has two loops iterating over connectors, the first for handling hotplug disabling due to irq storms and the second for actually handling the hotplug events. Move the debug printing into the second one, so we can abstract the storm handling better. This may change the output ordering slightly when there are multiple simultaneous hotplug events.

The skylake scalers depend on the cdclk freq, but that frequency can change during a modeset. So when a modeset happens calculate the new cdclk in the atomic state. With the transitional helpers gone the cached value can be used in the scaler, and committed after all crtc's are disabled. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=90874Signed-off-by:

Now that all planes are added during a modeset we can use the calculated changes before disabling a plane, and then either commit or force disable a plane before disabling the crtc. The code is shared with atomic_begin/flush, except watermark updating and vblank evasion are not used. This is needed for proper atomic suspend/resume support.

Read out the initial state, and add a quirk to force add all planes to crtc_state->plane_mask during initial commit. This will disable all planes during the initial modeset. The initial plane quirk is temporary, and will go away when hardware readout is fully atomic, and the watermark updates in intel_sprite.c are removed. Changes since v1: - Unset state->visible on !primary planes. - Do not rely on the plane->crtc pointer in intel_atomic_plane, instead assume planes are invisible until modeset. Signed-off-by:

All the checks in intel_modeset_checks are only useful when a modeset occurs, because there is nothing to update otherwise. Same for power/cdclk changes, if there is no modeset they are noops. Unfortunately intel_modeset_pipe_config still gets called without modeset, because atomic hw readout isn't done yet. Signed-off-by:

The idea was good, but planes can have a fb even though they're disabled. This makes the force argument useless and always true, because only the commit function updates state. Signed-off-by:

In order for gen8+ hardware to guarantee that no context switch takes place during engine reset and that current context is properly saved, the driver needs to notify and query hw before commencing with reset. There are gpu hangs where the engine gets so stuck that it never will report to be ready for reset. We could proceed with reset anyway, but with some hangs with skl, the forced gpu reset will result in a system hang. By inspecting the unreadiness for reset seems to correlate with the probable system hang. We will only proceed with reset if all engines report that they are ready for reset. If root cause for system hang is found and can be worked around with another means, we can reconsider if we can reinstate full reset for unreadiness case. v2: -EIO, Recovery, gen8 (Chris, Tomas, Daniel) v3: updated commit msg v4: timeout_ms, simpler error path (Chris) References: https://bugs.freedesktop.org/show_bug.cgi?id=89959 References: https://bugs.freedesktop.org/show_bug.cgi?id=90854 Testcase: igt/gem_concurrent_blit/prw-blt-overwrite-source-read-rcs-forked Testcase: igt/gem_concurrent_blit/gtt-blt-overwrite-source-read-rcs-forked Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Tomas Elf <tomas.elf@intel.com> Reviewed-by:

We need to call drm_atomic_set_mode_for_crtc() rather than copying the mode in manually. As of commit commit 99cf4a29 Author: Daniel Stone <daniels@collabora.com> Date: Mon May 25 19:11:51 2015 +0100 drm/atomic: Add current-mode blob to CRTC state the helper now also takes care of setting up the mode property blob for us; if we don't use the helper and never setup the mode blob, this will also trigger a failure in drm_atomic_crtc_check() when we have the DRIVER_ATOMIC flag set (i.e., when using the nuclear pageflip support via i915.nuclear_pageflip kernel command line parameter).

We already had a few bugs in the past where FBC was compressing nothing when it was enabled, which makes the feature quite useless.

The docs don't support the 64k linear scanout alignment we impose on gen2/3. And it really makes no sense since we have no DSPSURF register, so the only thing that the hardware will see is the linear offset which will be just pixel aligned anyway. There is one case where 64k comes into the picture, and that's FBC. The start of the line length buffer corresponds to a 64k aligned address of the uncompressed framebuffer. So if the uncompressed fb is not 64k aligned, the first actually used entry in the line length buffer will not be byte 0. There are 32 extra entries in the line length buffer to account for this extra alignment so we shouldn't have to worry about it when mapping the uncompressed fb to the GTT. Signed-off-by:

VLV/CHV have problems with 4k aligned linear scanout buffers. The VLV docs got updated at some point to say that we need to align them to 128k, just like we do on gen4. So far I've seen the problem manifest when the stride is an odd multiple of 512 bytes, and the surface address meets the following pattern '(addr & 0xf000) == 0x1000' (also == 0x2000 is problematic on VLV). The result is a starcase effect (so some pages get dropped maybe?), with a few pages here and there clearly getting scannout out at the wrong position. I've not actually been able to reproduce this problem on gen4, so it's not clear of the issue is any way related to the 128k restrictions supposedly inherited from gen4. But let's hope the 128k alignment is sufficient to hide it all. Signed-off-by:

Currently intel_gen4_compute_page_offset() simply picks the closest page boundary below the linear offset. That however may not be suitably aligned to satisfy any hardware specific restrictions. So let's make sure the page boundary we choose is properly aligned. Also to play it a bit safer lets split the remaining linear offset into x and y values instead of just x. This should make no difference for most platforms since we convert the x and y offsets back into a linear offset before feeding them to the hardware. HSW+ are different however and use x and y offsets even with linear buffers, so they might have trouble if either the x or y get too big. Signed-off-by:
