* gpu: nvgpu: move clk_gm20b debugfs to Linux moduleDeepak Nibade2017-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move debugfs code from clk_gm20b.c to file in Linux module common/linux/debug_clk.c This file will be compiled only if CONFIG_DEBUG_FS is set Define below new HAL APIs for various clock operations which can be accessed from debug file init_debugfs() get_voltage() get_gpcclk_clock_counter() pll_reg_write() get_pll_debug_data() Export nvgpu_pl_to_div() and nvgpu_div_to_pl() so that these can be accessed from debug_clk.c Add new structure nvgpu_clk_pll_debug_data so that all required register values for debugging can be made available in debug_clk.c Add new API gm20b_get_gpc_pll_parms() so that statically defined variable can be accessed in debug_clk.c too Remove global variable dvfs_safe_max_freq and add it to struct clk_gk20a so that it can accessed from both clk_gm20b.c and debug_clk.c Jira NVGPU-62 Change-Id: I3ae70b40235e78141a686686930e1f178ad59453 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1488903 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
* gpu: nvgpu: move gm20b clock register to platform fileDeepak Nibade2017-05-24
| | | | | | | | | | | | | | | | | | | | We currently register gm20b clock operations gm20b_clk_ops in function gm20b_register_gpcclk() which is in clk_gm20b.c Since this is common clock framework and hence linux dependency, move this clock registration to platform specific file Note that all the clock operations remain in clk_gm20b.c. APIs in platform file will eventually call operations in clk_gm20b.c Jira NVGPU-49 Change-Id: Ib0b0d9f4719b196d764825a7dddb08f1fbd7a567 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1483091 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
* gpu: nvgpu: use common nvgpu mutex/spinlock APIsDeepak Nibade2017-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using Linux APIs for mutex and spinlocks directly, use new APIs defined in <nvgpu/lock.h> Replace Linux specific mutex/spinlock declaration, init, lock, unlock APIs with new APIs e.g struct mutex is replaced by struct nvgpu_mutex and mutex_lock() is replaced by nvgpu_mutex_acquire() And also include <nvgpu/lock.h> instead of including <linux/mutex.h> and <linux/spinlock.h> Add explicit nvgpu/lock.h includes to below files to fix complilation failures. gk20a/platform_gk20a.h include/nvgpu/allocator.h Jira NVGPU-13 Change-Id: I81a05d21ecdbd90c2076a9f0aefd0e40b215bd33 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1293187 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

* gpu: nvgpu: Fix build without Tegra clk frameworkTerje Bergstrom2015-03-18
| | | | | | | | | | | | 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.
