This is leftover stuff from my previous doc round which I kinda wanted to do but didn't yet due to rebase hell. 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.

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.

Commit 457e77b2 added two checks applied to a value received from nv_rd32(bios, 0x619f04). But after this new piece of code is executed, the addr local variable does not hold the same value it used to hold before the commit. 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/tegra: Fixes for v3.15-rc2 This contains a fix for the host1x driver writing to non-existent syncpt registers. 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

The version of the drm_tegra_submit structure that was merged all the way back in 3.10 contains a pad field that was originally intended to properly pad the following __u64 field. Unfortunately it seems like a different field was dropped during review that caused this padding to become unnecessary, but the pad field wasn't removed at that time. One possible side-effect of this is that since the __u64 following the pad is now no longer properly aligned, the compiler may (or may not) introduce padding itself, which results in no predictable ABI. Rectify this by removing the pad field so that all fields are again naturally aligned. Technically this is breaking existing userspace ABI, but given that there aren't any (released) userspace drivers that make use of this yet, the fallout should be minimal.

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 <=.

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: NTomi Valkeinen <tomi.valkeinen@ti.com>

omap_crtc->old_fb is used to check whether the previous page flip has completed or not. However, it's never initialized to anything, so it's always NULL. This results in the check to always succeed, and the page_flip to proceed. Initialize old_fb to the fb that we intend to flip to through page_flip, and therefore prevent a future page flip to proceed if the last one didn't complete.

A waiter of the type OMAP_GEM_READ should wait for a buffer to be completely written, and only then proceed with reading it. A similar logic applies for waiters with OMAP_GEM_WRITE flag. Currently the function is_waiting() waits on the read_complete/read_target counts in the sync object. This should be the other way round, as a reader should wait for users who are 'writing' to this buffer, and vice versa. Make readers of the buffer(OMAP_GEM_READ) wait on the write counters, and writers to the buffer(OMAP_GEM_WRITE) wait on the read counters in is_waiting() Signed-off-by: NArchit Taneja <archit@ti.com> Signed-off-by: NTomi Valkeinen <tomi.valkeinen@ti.com>

smp_read_barrier_depends() can be used if there is data dependency between the readers - i.e. if the read operation after the barrier uses address that was obtained from the read operation before the barrier. In this file, there is only control dependency, no data dependecy, so the use of smp_read_barrier_depends() is incorrect. The code could fail in the following way: * the cpu predicts that idx < entries is true and starts executing the body of the for loop * the cpu fetches map->extent[0].first and map->extent[0].count * the cpu fetches map->nr_extents * the cpu verifies that idx < extents is true, so it commits the instructions in the body of the for loop The problem is that in this scenario, the cpu read map->extent[0].first and map->nr_extents in the wrong order.
