2014-03-28drm: drm_ut_debug_printk() isn't called with NULL anywmoreLespiau, Damien
The DRM_LOG* macros where the only sites where drm_ut_debug_printk was called with NULL arguments for prefix and function_name. Now that they are gone, we can remove that case. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2014-03-28drm: Pull the test on drm_debug in the logging macrosLespiau, Damien
In the logging code, we are currently checking is we need to output in drm_ut_debug_printk(). This is too late. The problem is that when we write something like: DRM_DEBUG_DRIVER("ELD on [CONNECTOR:%d:%s], [ENCODER:%d:%s]\n", connector->base.id, drm_get_connector_name(connector), connector->encoder->base.id, drm_get_encoder_name(connector->encoder)); We start by evaluating the arguments (so call drm_get_connector_name() and drm_get_connector_name()) before ending up in drm_ut_debug_printk() which will then does nothing. This means we execute a lot of instructions (drm_get_connector_name(), in turn, calls snprintf() for example) to happily discard them in the normal case, drm.debug=0. So, let's put the test on drm_debug earlier, in the macros themselves. Sprinkle an unlikely() as well for good measure.

2014-03-27drm/bridge: PTN3460 needs DRM_KMS_HELPERArnd Bergmann
The recently added PTN3460 device driver uses interfaces that are provided by the KMS helper infrastructure, so we should explicitly select that to avoid this linker error: ERROR: "drm_helper_probe_single_connector_modes" [drivers/gpu/drm/bridge/ptn3460.ko] undefined! ERROR: "drm_helper_connector_dpms" [drivers/gpu/drm/bridge/ptn3460.ko] undefined! We have to drop the I2C dependency to avoid a circular dependency chain, but that's ok because DRM already selects I2C.

2014-03-26drm/nouveau/bios: fetch the vbios from PROM using only aligned 32-bit accessesMartin Peres
Other kind of accesses are unreliable on Kepler cards. As advised by NVIDIA, let's only use 32-bit accesses to fetch the vbios from PROM. This fixes vbios fetching on my nve7 which failed in certain specific conditions. I suggest we Cc stable, for all kernels they still maintain after the big rewrite.

This should fix automatic fan management on fermi cards who do not have 0x46 entries in the thermal table. On my nve6, the blob sets the default linear range from 40°C to 100°C but my nvcf's default values are 40°C to 85°C. Let's keep 85 as a default for everyone.

2014-03-26drm/nouveau: fix small thinko in vblank timestamping.Mario Kleiner
*hpos horizontal scanout position doesn't need to be corrected to count the pixels between hactive end and htotal negative. That is only needed for *vpos to count lines until end of vblank for the vblank timestamping. Use hpos as is without correction. Removes occassional spikes in timestamps of up to 1 scanline duration, thereby improves accuracy to about +/- 2 usecs instead of +/- 12 usecs, wrt. true onset time as measured with high precision equipment on NV-A5.

2014-03-26support for platform devicesAlexandre Courbot
Upcoming mobile Kepler GPUs (such as GK20A) use the platform bus instead of PCI to which Nouveau is tightly dependent. This patch allows Nouveau to handle platform devices by: - abstracting PCI-dependent functions that were typically used for resource querying and page mapping, - introducing a nv_device_is_pci() function that allows to make PCI-dependent code conditional, - providing a nouveau_drm_platform_probe() function that takes a GPU platform device to be probed. Core code as well as engine/subdev drivers are updated wherever possible to make use of these functions. Some older drivers are too dependent on PCI to be properly updated, but all newer code on which future chips may depend should at least be runnable with platform devices.
