* gpu: nvgpu: Move gk20a_scale to be Linux onlyTerje Bergstrom2017-11-01
| | | | | | | | | | | | | | | Move gk20a_scale.[ch] to be common/linux/scale.[ch]. The code is Linux specific, and only referred from Linux specific source files. Change the license back to GPL.

* gpu: nvgpu: move freq clipping to target functionDeepak Nibade2016-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | We right now obtain pm_qos frequency requirments in qos notifier callback gk20a_scale_qos_notify() But now we want to limit GPU frequencies based on frequency limited from devfreq nodes And devfreq requirement should precede over qos requirements Hence, move all frequency estimation and clipping to function gk20a_scale_target() which sets the frequency at the end Bug 200245796 Change-Id: I0572c676dce0acc0917924a11e4c0fb4a9db4e6e Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1243427 (cherry picked from commit 81c757a3232463d126aecba64ca0c55d8e4423d2) Reviewed-on: http://git-master/r/1239936 Reviewed-by: Aaron Huang <aaronh@nvidia.com> Tested-by: Aaron Huang <aaronh@nvidia.com> Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
* gpu: nvgpu: add QoS notifier for common clk frameworkDeepak Nibade2016-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Define specific QoS notifier for common clk framework and protect it with CONFIG_COMMON_CLK This new API will first get min/max requirements from pm_qos and set min/max freq values in devfreq A call to update_devfreq() will then ensure that new estimated frequency is clipped appropriately between min and max values This also ensures that frequency is set along with all the book-keeping Add below platform specific notifier callback and use it with pm_qos_add_notifier() int (*qos_notify)() If qos_notify is set, then only register the callback We currently support only one qos_id which is treated as notifier for min frequency Remove dependency on qos_id, and use appropriate QoS APIs like pm_qos_read_min/max_bound() Store devfreq's min/max frequency in struct gk20a for reference Bug 1772462 Change-Id: I63d6d17451d19c9d376b67df7db775b38929287d Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1161161 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Tested-by: Terje Bergstrom <tbergstrom@nvidia.com>
* gpu: nvgpu: Use device instead of platform_deviceTerje Bergstrom2016-04-08
| | | | | | | | | Use struct device instead of struct platform_device wherever possible. This allows adding other bus types later. Change-Id: I1657287a68d85a542cdbdd8a00d1902c3d6e00ed Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: http://git-master/r/1120466

| | | | | | | | | | | | Do not build clock code if TEGRA_CLK_FRAMEWORK is not defined. Also make GK20A_DEVFREQ depend on TEGRA_CLK_FRAMEWORK, and build scaling governor only if GK20A_DEVFREQ is enabled.

* gpu: nvgpu: rename gpu ioctls and structs to nvgpuKonsta Holtta2015-03-18
| | | | | | | | | | | | | | To help remove the nvhost dependency from nvgpu, rename ioctl defines and structures used by nvgpu such that nvhost is replaced by nvgpu. Duplicate some structures as needed. Update header guards and such accordingly.
