2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-1/+1
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

2017-03-14drm/gem: Add DEFINE_DRM_GEM_FOPSDaniel Vetter1-10/+1
Sadly there's only 1 driver which can use it, everyone else is special for some reason: - gma500 has a horrible runtime PM ioctl wrapper that probably doesn't really work but meh. - i915 needs special compat_ioctl handler because regrets. - arcgpu needs to fixup the pgprot because (no idea why it can't do that in the fault handler like everyone else). - tegra does even worse stuff with pgprot - udl does something with vm_flags too ... - cma helpers, etnaviv, mtk, msm, rockchip, omap all implement some variation on prefaulting. - exynos is exynos, I got lost in the midlayers. - vc4 has to reinvent half of cma helpers because those are too much midlayer, plus vm_flags dances. - vgem also seems unhappy with the default vm_flags. So pretty sad divergence and I'm sure we could do better, but not really an idea. Oh well, maybe this macro here helps to encourage more consistency at least going forward.

2017-02-07drm: armada: use vblank hooks in struct drm_crtc_funcsShawn Guo1-16/+0
The vblank hooks in struct drm_driver are deprecated and only meant for legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks in struct drm_crtc_funcs should be used instead. As the result, functions armada_drm_crtc_enable[disable]_irq() can be static, although they are moved around a bit to save forward declaration. The armada_crtc pointer array in struct armada_private is still kept in there, because armada_debugfs.c still have reference to it.

2016-11-17drm/armada: de-midlayer armadaRussell King1-108/+128
Now that the drm_connector_register() is gone from tda998x, we can remove the mid-layer from armada-drm, eliminating the load, unload, debugfs_init, and debugfs_cleanup callbacks from armada's drm_driver structure. No functional changes. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

2016-08-16drm: drop DRIVER_HAVE_IRQ flag for some driversShawn Guo1-1/+1
Since commit 4984979b9b90 ("drm/irq: simplify irq checks in drm_wait_vblank"), the drm driver feature flag DRIVER_HAVE_IRQ is only required for drivers that have an IRQ handler managed by the DRM core. Some drivers, armada, etnaviv, kirin and sti, set this flag without .irq_handler setup in drm_driver. These drivers manage IRQ handler by themselves and the flag DRIVER_HAVE_IRQ makes no sense there. Drop the flag for these drivers to avoid confusion.

2016-06-21drm: Lobotomize set_busid nonsense for !pci driversDaniel Vetter1-1/+0
We already have a fallback in place to fill out the unique from dev->unique, which is set to something reasonable in drm_dev_alloc. Which means we only need to have a special set_busid for pci devices, to be able to care the backwards compat code for drm 1.1 around, which libdrm still needs. While developing and testing this patch things blew up in really interesting ways, and the code is rather confusing in naming things between the kernel code, ioctl #defines and libdrm. For the next brave dragon slayer, document all this madness properly in the userspace interface section of gpu.tmpl. v2: Make drm_dev_set_unique static and update kerneldoc. v3: Entire rewrite, plus document what's going on for posterity in the gpu docbook uapi section. v4: Drop accidental amdgpu hunk (Emil). v5: Drop accidental omapdrm vblank counter change (Emil). v6: Rebase on top of the sphinx conversion.

This was added in commit 0a3e67a4caac273a3bfc4ced3da364830b1ab241 Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Tue Sep 30 12:14:26 2008 -0700 drm: Rework vblank-wait handling to allow interrupt reduction. to stay backwards-compatible with old UMS code that didn't even tell the kernel when it did a modeset, so that the kernel could save/restore vblank counters. At worst this means vblanks will be somewhat funky on a setup that very likely no one still runs. So let's just nuke it. Plan B would be to set it unconditionally in drm_vblank_init for kms drivers, instead of in each driver separately. So if this patch breaks anything please only restore the hunks in drmP.h and drm_irq.c, plus add a check for DRIVER_MODESET in drm_vblank_init. Stumbled over this in a discussion on irc with Chris.

2015-10-20drm/armada: Convert the probe function to the generic drm_of_component_probe()Liviu Dudau1-49/+19
The armada DRM driver keeps some old platform data compatibility in the probe function that makes moving to the generic drm_of_component_probe() a bit more complicated that it should. Refactor the probe function to do the platform_data processing after the generic probe (and only if that fails). This way future cleanup can further remove support for it.

Just one special case (since i915 lost its ums code, yay): - radeon: Has slots for the old ums ioctls which don't have DRM_UNLOCKED, but all filled with drm_invalid_op. So ok to drop it everywhere. Every other kms driver just has DRM_UNLOCKED for all their ioctls, as they should. v2: admgpu happened, include that one too. And i915 lost its UMS support which means we can change all the i915 ioctls too. v3: Rebased on top of new vmwgfx DX interface extensions. v4: Rebase on top of render-node support in exynos.

2015-10-07drm: Stop using drm_vblank_count() as the hw frame counterVille Syrjälä1-1/+1
drm_vblank_count() returns the software counter. We should not pretend it's the hw counter since we use the hw counter to figuere out what the software counter value should be. So instead provide a new function drm_vblank_no_hw_counter() for drivers that don't have a real hw counter. The new function simply returns 0, which is about the only thing it can do.

As per recent discussion, the drm_vblank_pre_modeset() calls can cause deadlock with other changes to generic code.
