Daniel was looking at this code and asked about whether fb->pitches[0] is correct, then he suggested we should a comment to make sure it is actually intentional.

If we run igt/kms_frontbuffer_tracking, this message will appear thousands of times, eating a significant part of our dmesg buffer. It's part of the expected FBC behavior, so let's just silence it.

Make sure we deactivate FBC at intel_fbc_init(), so we can remove the call from intel_display.c. Currently we only have the "enabled" software state, but later we'll have both "enabled" and "active", and we'll add assertions to them, so just calling intel_fbc_disable() from intel_modeset_init() won't work. It's better to make sure intel_fbc_init() already puts the hardware in the expected state, so we can put nice assertions in the other functions. v2: Keep/improve the comment (Chris). v3: Improve the commit message a little bit.

If FBC is disabled we will still call intel_fbc_invalidate(), and as a result we may call intel_fbc_deactivate(), which will try to touch registers. I'm pretty sure I saw this happen on a runtime suspended device, and I'm almost sure I was running igt/pm_rpm. It produced the "you touched registers while the device is suspended" WARNs. But this was some time ago and I can't remember exactly which conditions were necessary to reproduce the problem. v2: Rebase to new series order.

Don't try to list in comments the cases where we should enable or disable FBC: it varies a lot with the hardware generations and the code should be the documentation. Also notice that there's already a huge gap between the comments and what's in the code.

This change was part of the commit that makes intel_fbc_update() receive an intel_crtc as argument instead of dev_priv, but since it was polluting the diff with too many chunks I decided to move it to its own commit. It seems that our developers are favoring having this instead of the old combination drm_crtc *crtc + intel_crtc *intel_crtc, and on the mentioned commit we'll get rid of the drm_crtc variable, so let's do an intermediate commit with the rename, so on the next commit we'll have just struct intel_crtc *crtc.

Matt Roper authored
The bspec indicates that DDI A using four lanes is the only valid configuration for Broxton (Broxton doesn't have a DDI E to split these lanes with); the DDI_A_4_LANES bit of port A's DDI_BUF_CTL should always be set by the BIOS. However some BIOS versions seem to only be setting this bit if eDP is actually lit up at boot time; if the BIOS doesn't turn on the eDP panel because an external display is plugged in, then this bit is never properly initialized. The end result of this is that we wind up calculating a lower max data rate than we should and may wind up rejecting the native mode for panels that we should be able to drive. Let's workaround this BIOS bug by just turning the DDI_A_4_LANES bit on in our driver's internal state if we recognize that we're running on BXT where it should have been on anyway.

VMA offsets are 64 bits. Plane surface offsets are in ggtt and the hardware register to set this is thus 32 bits. Be explicit about these and convert carefully to from vma to final size. This will make sparse happy by not creating 32bit pointers out of 64bit vma offsets.

There is known issue on GT interrupt delivery with DC6 and firmwares <1.21. There is a suspicion that this causes spurious gpu hangs on driver init and with some workloads, as upgrading the firmware to 1.21 makes these problems disappear. As of now the current version included in distribution firmware packages is very like to be 1.19. Play it safe and refuse to load a firmware version that may affect gpu side stability.

We had two failure modes here: 1. Deadlock in intelfb_alloc failure path where it calls drm_framebuffer_remove, which grabs the struct mutex and intelfb_create (caller of intelfb_alloc) was already holding it. 2. Deadlock in intelfb_create failure path where it calls drm_framebuffer_unreference, which grabs the struct mutex and intelfb_create was already holding it. [Daniel Vetter on why struct_mutex needs to be locked in the second half of intelfb_create: "The vma [for the fbdev] is pinned, the problem is that we re-lookup it a few times, which is racy. We should instead track the vma directly, but oh well we don't."] v2: * Reformat commit msg to 72 chars. (Lukas Wunner) * Add third failure mode. (Lukas Wunner) v5: * Rebase on drm-intel-nightly 2015y-09m-01d-09h-06m-08s UTC, rephrase commit message. (Jani Nicula) v6: * In intelfb_alloc, if __intel_framebuffer_create failed, fb will be an ERR_PTR, thus not null. So in the failure path we need to check for IS_ERR_OR_NULL to avoid calling drm_framebuffer_remove on the ERR_PTR. (Lukas Wunner) * Since this is init code a drm_framebuffer_unreference should be all we need. drm_framebuffer_remove is for framebuffers that userspace has created - and is getting somewhat defeatured. (Daniel Vetter) v7: * Clarify why struct_mutex needs to be locked in the second half of intelfb_create.

Currently when allocating a framebuffer fails, the gem object gets unrefed at the bottom of the call stack in __intel_framebuffer_create, not where it gets refed, which is in intel_framebuffer_create_for_mode (via i915_gem_alloc_object) and in intel_user_framebuffer_create (via drm_gem_object_lookup). This invites mistakes: __intel_framebuffer_create is also called from intelfb_alloc, and as discovered by Tvrtko Ursulin, a double unref was introduced there with a8bb6818 ("drm/i915: Fix error path leak in fbdev fb allocation"). As suggested by Ville Syrjälä, fix the double unref and improve code clarity by moving the unref away from __intel_framebuffer_create to where the gem object gets refed.

BXT CRTC scaling uses the same gen9 codepaths as SKL; these codepaths store panel fitter information in pipe_config->pch_pfit. However since HAS_PCH_SPLIT() is false for BXT we never actually wind up filling in this structure (we wind up filling in pipe_config->gmch_pfit instead, which is ignored when we go to program the hardware). Make sure we always take the PCH code path on gen9+ platforms. v2: Use HAS_GMCH_DISPLAY() to more cleanly describe the platforms that actually want to use GMCH-style panel fitting.

I wanted to add yet another check to intel_fbc_update() and realized I would need to create yet another enum no_fbc_reason case. So I remembered this patch series that Damien wrote a long time ago and nobody ever reviewed, so I decided to reimplement it since the code changed a lot since then.

Make pinning and waiting a separate step, and wait for object idle without struct_mutex held. Changes since v1: - Do not wait when a reset is in progress. - Remove call to i915_gem_object_wait_rendering for intel_overlay_do_put_image (Chris Wilson) Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>

struct_mutex is being locked for every plane in intel_prepare_plane_fb and intel_cleanup_plane_fb. Require the caller to hold the mutex, and only acquire the mutex for each helper call. This way the lock only needs to be acquired twice in ->atomic_commit(). Once for pinning new framebuffers at the start, the second time for unpinning old framebuffer. Changes since v1: - Use mutex_lock_interruptible instead of i915 variant, to prevent a deadlock when called from the reset code. Changes since v2: - Clarify struct_mutex is locked by the caller.

Move it from intel_crtc_atomic_commit to prepare_plane_fb. Waiting is done before committing, otherwise it's too late to undo the changes.

Extends i915_display_info so that for each active crtc also print all planes associated with the pipe. This patch shows information about each plane wrt format, size, position, rotation, and scaling. This is very useful when debugging user space compositors that try to utilize several planes for a commit. V2: Fixed comments from Maarten, Ville, and Chris. Fixed printing of 16.16 fixpoint, better rotation bitmask management and some minor fixes V3: Corrected state->src_x & 0x00ff to state->src_x & 0xffff...

One branch of the if clause uses pr_info, the other pr_err; change the 'false' branch to also use pr_info. This minor oversight has gone unfixed since the initial vga_switcheroo implementation in 6a9ee8af.
