2017-02-24mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmfDave Jiang
->fault(), ->page_mkwrite(), and ->pfn_mkwrite() calls do not need to take a vma and vmf parameter when the vma already resides in vmf. Remove the vma parameter to simplify things.

2017-02-02drm: Rely on mode_config data for fb_helper initializationGabriel Krisman Bertazi
Instead of receiving the num_crts as a parameter, we can read it directly from the mode_config structure. I audited the drivers that invoke this helper and I believe all of them initialize the mode_config struct accordingly, prior to calling the fb_helper. I used the following coccinelle hack to make this transformation, except for the function headers and comment updates. The first and second rules are split because I couldn't find a way to remove the unused temporary variables at the same time I removed the parameter. // <smpl> @r@ expression A,B,D,E; identifier C; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ expression A,B,C,D,E; @@ ( - drm_fb_helper_init(A,B,C,D) + drm_fb_helper_init(A,B,D) | - drm_fbdev_cma_init_with_funcs(A,B,C,D,E) + drm_fbdev_cma_init_with_funcs(A,B,D,E) | - drm_fbdev_cma_init(A,B,C,D) + drm_fbdev_cma_init(A,B,D) ) @@ identifier r.C; type T; expression V; @@ - T C; <... when != C - C = V; ...> // </smpl> Changes since v1: - Rebased on top of the tip of drm-misc-next. - Remove mention to sti since a proper fix got merged.

This avoids using the deprecated drm_get_pci_dev() and load() hook interfaces in the qxl driver.

2017-01-17drm: qxl: Let DRM core handle connector registeringGabriel Krisman Bertazi
Registering the connector explicitly right after creation is not necessary for modesetting drivers, because drm_dev_register already takes care of this on the core side, by calling drm_modeset_register_all. In addition, performing the initialization too early will get in the way of the load() hook removal, because the connector interface cannot be published prior to registering the minors.

<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of <drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not needed in the header. <drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.

Instead I did the unsafe way, and tried to look over the entire diff to spot if any dangerous expressions were produced. I didn't see any.

2016-11-15qxl: Allow resolution which are not multiple of 8Christophe Fergeau
The use of drm_cvt_mode() in qxl_add_monitors_config_modes() means that the resolutions we are going to present to user-space are going to be rounded down to a multiple of 8. In the QXL arbitrary resolution case, this is not useful. This commit forces the actual width/height that was requested by the client in the drm_display_mode structure rather than keeping the rounded version.

2016-11-15qxl: Don't notify userspace when monitors config is unchangedChristophe Fergeau
When the QXL driver receives a QXL_INTERRUPT_CLIENT_MONITORS_CONFIG interrupt, we currently always notify userspace that there was some hotplug event. However, gnome-shell/mutter is reacting to this event by attempting a resolution change, which it does by issueing drmModeRmFB, drmModeAddFB, and then drmModeSetCrtc. This has the side-effect of causing qxl_crtc_mode_set() to tell the QXL virtual hardware that a primary surface was destroyed and created. After going through QEMU and then the remote SPICE client, a new identical monitors config message will be sent, resulting in a QXL_INTERRUPT_CLIENT_MONITORS_CONFIG interrupt to be emitted, and the same scenario occurring again. As destroying/creating the primary surface causes a visible screen flicker, this makes the guest hard to use ( https://bugzilla.redhat.com/show_bug.cgi?id=1266484 ). This commit checks if the screen configuration we received is the same one as the current one, and does not notify userspace about it if that's the case.

2016-10-25dma-buf: Rename struct fence to dma_fenceChris Wilson
I plan to usurp the short name of struct fence for a core kernel struct, and so I need to rename the specialised fence/timeline for DMA operations to make room. A consensus was reached in https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html that making clear this fence applies to DMA operations was a good thing. Since then the patch has grown a bit as usage increases, so hopefully it remains a good thing!

2016-09-20drm/qxl: reapply cursor after SetCrtc callsRay Strode
The qxl driver currently destroys and recreates the qxl "primary" any time the first crtc is set. A side-effect of destroying the primary is mouse state associated with the crtc is lost, which leads to disappearing mouse cursors on wayland sessions. This commit changes the driver to reapply the cursor any time SetCrtc is called. It achieves this by keeping a reference to the cursor bo on the qxl_crtc struct.
