This adds support for the Armada 510 display subsystem found on the Marvell Dove devices. This IP is re-used across several different Marvell SoCs with various tweaks, and this driver has been structured to allow the other IPs to re-use the bulk of this code; further work in this area is expected from interested parties. This has been extensively tested on the SolidRun Cubox platform and appears to work well there. [airlied: update for api changes merged previous to this]

So drm was abusing device lifetimes, by having embedded device structures in the minor and connector it meant that the lifetime of the internal drm objects (drm_minor and drm_connector) were tied to the lifetime of the device files in sysfs, so if something kept those files opened the current code would kfree the objects and things would go downhill from there. Now in reality there is no need for these lifetimes to be so intertwined, especailly with hotplugging of devices where we wish to remove the sysfs and userspace facing pieces before we can unwind the internal objects due to open userspace files or mmaps, so split the objects out so the struct device is no longer embedded and do what fbdev does and just allocate and remove the sysfs inodes separately.

This patch adds support for the pair of LCD controllers on the Marvell Armada 510 SoCs. This driver supports: - multiple contiguous scanout buffers for video and graphics - shm backed cacheable buffer objects for X pixmaps for Vivante GPU acceleration - dual lcd0 and lcd1 crt operation - video overlay on each LCD crt via DRM planes - page flipping of the main scanout buffers - DRM prime for buffer export/import This driver is trivial to extend to other Armada SoCs. Included in this commit is the core driver with no output support; output support is platform and encoder driver dependent. Tested-by:

The conflict in intel_drv.h tripped me up a bit since a patch in dinq moves all the functions around, but another one in drm-next removes a single function. So I'ev figured backing this into a backmerge would be good. i915_dma.c is just adjacent lines changed, nothing nefarious there.

If the firmware is not builtin and userspace is not yet running, we can stall the boot process for a minute whilst the firmware loader times out. This is contrary to expectations of providing a builtin EDID! In the process, we can rearrange the code to make the error handling more resilient and prevent gcc warning about unitialised variables along the error paths. v2: Load builtins first, fix gcc second (Jani) and cosmetics (Ville). v3: Verify that we do not read beyond the end of the fwdata (Ville) Signed-off-by:

Analog to drm_dev_register(), we now provide drm_dev_unregister() which does the reverse. drm_dev_put() is still in place and combines the calls to drm_dev_unregister() and drm_dev_free() so buses don't have to change. *_get() and *_put() are used for reference-counting in the kernel. However, drm_dev_put() definitely does not do any kind of ref-counting. Hence, use the more appropriate *_register(), *_unregister(), *_alloc() and *_free() names. Signed-off-by:

The error paths in DRM bus drivers currently leak memory as they don't correctly revert drm_dev_alloc(). Introduce drm_dev_free() to free DRM devices which haven't been registered, yet. We must be careful not to introduce any side-effects with cleanups done in drm_dev_free(). drm_ht_remove(), drm_ctxbitmap_cleanup() and drm_gem_destroy() are all fine in that regard. Signed-off-by:

Try to keep all functions that handle DRM file_operations in drm_fops.c so internal helpers can be marked static later. This makes the split between the 3 core files more obvious: - drm_stub.c: DRM device allocation/destruction and management - drm_fops.c: DRM file_operations (except for ioctl) - drm_drv.c: Global DRM init + ioctl handling Well, ioctl handling is still spread throughout hundreds of source files, but at least the others are clearly defined this way.

All bus drivers do device setup themselves. This requires us to adjust all of them if we introduce new core features. Thus, merge all these into a uniform drm_dev_register() helper. Note that this removes the drm_lastclose() error path for AGP as it is horribly broken. Moreover, no bus driver called this in any other error path either. Instead, we use the recently introduced AGP cleanup helpers. We also keep a DRIVER_MODESET condition around pci_set_drvdata() to keep semantics.

Instead of managing device allocation+initialization in each bus-driver, we should do that in a central place. drm_fill_in_dev() already does most of it, but also requires the global drm lock for partial AGP device registration. Split both apart so we have a clean device initialization/allocation phase, and a registration phase. Signed-off-by:

All drivers embed gem-objects into their own buffer objects. There is no reason to keep drm_gem_object_alloc(), gem->driver_private and ->gem_init_object() anymore. New drivers are highly encouraged to do the same. There is no benefit in allocating gem-objects separately.

There is no reason to keep the gem object separately allocated. nouveau is the last user of gem_obj->driver_private, so if we embed it, we can get rid of 8bytes per gem-object. The implementation follows the radeon driver. bo->gem is only valid, iff the bo was created via the gem helpers _and_ iff the user holds a valid gem reference. That is, as the gem object holds a reference to the nouveau_bo. If you use nouveau_ref() to gain a bo reference, you are not guaranteed to also hold a gem reference. The gem object might get destroyed after the last user drops the gem-ref via drm_gem_object_unreference(). Use drm_gem_object_reference() to gain a gem-reference. For debugging, we can use bo->gem.filp != NULL to test whether a gem-bo is valid. However, this shouldn't be used for real functionality to avoid gem-internal dependencies. Note that the implementation follows the previous style. However, we no longer can check for bo->gem != NULL to test for a valid gem object. This wasn't done before, so we should be safe now.

After applying wait-boost we often find ourselves stuck at higher clocks than required. The current threshold value requires the GPU to be continuously and completely idle for 313ms before it is dropped by one bin. Conversely, we require the GPU to be busy for an average of 90% over a 84ms period before we upclock. So the current thresholds almost never downclock the GPU, and respond very slowly to sudden demands for more power. It is easy to observe that we currently lock into the wrong bin and both underperform in benchmarks and consume more power than optimal (just by repeating the task and measuring the different results). An alternative approach, as discussed in the bspec, is to use a continuous threshold for upclocking, and an average value for downclocking. This is good for quickly detecting and reacting to state changes within a frame, however it fails with the common throttling method of waiting upon the outstanding frame - at least it is difficult to choose a threshold that works well at 15,000fps and at 60fps. So continue to use average busy/idle loads to determine frequency change. v2: Use 3 power zones to keep frequencies low in steady-state mostly idle (e.g. scrolling, interactive 2D drawing), and frequencies high for demanding games. In between those end-states, we use a fast-reclocking algorithm to converge more quickly on the desired bin. v3: Bug fixes - make sure we reset adj after switching power zones. v4: Tune - drop the continuous busy thresholds as it prevents us from choosing the right frequency for glxgears style swap benchmarks. Instead the goal is to be able to find the right clocks irrespective of the wait-boost. Signed-off-by:
