The modeset helpers and the probing helpers a independent and e.g. i915 uses the probing stuff but has its own modeset infrastructure. It hence makes to split this up. While at it add a DOC: comment for the probing libraray. It would be rather neat to pull some of the DocBook documenting these two helpers into in-line DOC: comments. But unfortunately kerneldoc doesn't support markdown or something similar to make nice-looking documentation, so the current state is better.

* | drm/plane-helper: Don't fake-implement primary plane disablingDaniel Vetter2014-04-181-28/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After thinking about this topic a bit more I've reached the conclusion that implementing this doesn't make sense: - The locking is all wrong: set_config(NULL) will also unlink encoders and connectors, but those links are protected with the mode_config mutex. In the ->disable_plane callback we only hold all modeset locks, but eventually we want to switch to just grabbing the per-crtc (and maybe per-plane) locks as needed, maybe based on ww_mutexes. Having a callback which absolutely needs all modeset locks is bad for this conversion. Note that the same isn't true for the provided ->update_plane since we've audited the crtc helpers to make sure that not encoder or connector links are changed. - There's no way to re-enable the plane with an ->update_plane: The connectors/encoder links are lost and so we can't re-enable the CRTC. Even without that issue the driver might have reassigned some shared resources (as opposed to e.g. DPMS off, where drivers are not allowed to do that to make sure the CRTC can be enabled again). - The semantics don't make much sense: Userspace asked to scan out black (or some other color if the driver supports a background color), not that the screen be disabled. - Implementing proper primary plane support (i.e. actually disabling the primary plane without disabling the CRTC) is really simple, at least if all the hw needs is flipping a bit. The big task is auditing all the interactions with other ioctls when the CRTC is on but there's no primary plane (e.g. pageflips). And some of that work still needs to be done.

Here is what is was assigned in the original code: (u64)(nv_rd32(bios, 0x619f04) & 0xffffff00) << 8 in the committed code it ends up with this value: (u64)(nv_rd32(bios, 0x619f04) >> 8) << 8 These expressions are obviously not equivalent. My Nvidia video card does not show anything on the display when I boot a kernel containing this commit. The patch fixes the code so that the new checks are still done, but the side effect of an incorrect addr value is gone.

| * | drm/omap: fix the handling of fb ref countsTomi Valkeinen2014-04-151-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the recent primary-plane changes for drm, the primary plane's framebuffer needs to be ref counted the same way as for non-primary-planes. This was not done by the omapdrm driver, which caused the ref count to drop to 0 too early, causing problems. This patch moves the fb unref and ref from omap_plane_update to omap_plane_mode_set. This way the fb refs are updated for both primary and non-primary cases, as omap_plane_update calls omap_plane_mode_set. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

This should be the other way round, as a reader should wait for users who are 'writing' to this buffer, and vice versa.

However, this doesn't work correctly. The encoder driver has to be in control of its video input (i.e. the crtc) for correct operation. This problem causes bugs with (at least) HDMI: the HDMI encoder supplies pixel clock for DISPC, and DISPC supplies video stream for HDMI. The current code first enables the HDMI encoder, and CRTC after that. However, the encoder expects the video stream to start during the encoder's enable, and if it doesn't, there will be sync lost errors. The encoder enables its video source by calling src->enable(), and this call goes to omapdrm (omap_crtc_enable), but omapdrm doesn't do anything in that function. Similarly for disable, which goes to omap_crtc_disable(). This patch moves the code to setup and enable/disable the crtc to omap_crtc_enable. and omap_crtc_disable().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At module unload, omap_fbdev_free() gets called which releases the framebuffers. However, the framebuffers are still used by crtcs, and will be released only later at vsync. The driver doesn't wait for this, and goes on to release the rest of the resources, which often causes a crash. This patchs adds a omap_crtc_flush() function which waits until the crtc has finished with its apply queue and page flips. The function utilizes a simple polling while-loop, as the performance is not an issue here. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Rob Clark <robdclark@gmail.com>

The driver does disable the sync-lost irq properly, but it fails to wait until the output has been fully enabled (i.e. the first vsync), so the sync-lost errors are still seen occasionally. This patch makes the omapdrm act the same way as the omapfb does: - When enabling a display, we'll wait for the first vsync. - When disabling a display, we'll wait for framedone if available, or odd and even vsyncs. These changes make sure the output is fully enabled or disabled at the end of the function.

A second commit removes an excess pad field in the parameter structure for the DRM_TEGRA_SUBMIT IOCTL. Archeaology on earlier versions of this file indicates that this was once there to pad an uneven number of u32 u32 fields, of which one was subsequently removed. Unfortunately nobody remembered to get rid of the padding when that happened. Both of these commits are Cc: stable because they fix issues that were introduced back in v3.10. * tag 'drm/tegra/for-3.15-rc2' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: Remove gratuitous pad field gpu: host1x: handle the correct # of syncpt regs

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BIT_WORD() truncates rather than rounds, so the loops in syncpt_thresh_isr() and _host1x_intr_disable_all_syncpt_intrs() use <= rather than < in an attempt to process the correct number of registers when rounding of the conversion of count of bits to count of words is necessary. However, when rounding isn't necessary because the value is already a multiple of the divisor (as is the case for all values of nb_pts the code actually sees), this causes one too many registers to be processed. Solve this by using and explicit DIV_ROUND_UP() call, rather than BIT_WORD(), and comparing with < rather than <=.
