* gpu: nvgpu: fix resource leakDeepak Nibade2017-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | We pass (struct device_attribute *) to gp10b_ecc_stat_create() and gr_gp10b_ecc_stat_create() and then assign a memory allocation to this pointer But since this pointer is local copy to function, static pointer variables are never set in gr_gp10b_create_sysfs() This also results in a resource leak since we never free the storage assigned to local variable Fix this by adding correct parameter (struct device_attribute **) so that the address of the allocation is returned to the caller correctly Bug 200291879 Coverity id : 2567934 Change-Id: I7ac79810d9e22a568ae3cd1a69eb3f59a8d356ac Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1495905 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Sachin Nikam <snikam@nvidia.com> Reviewed-by: svccoveritychecker <svccoveritychecker@nvidia.com>

* gpu: nvgpu: remove duplicate \n from log messagesStephen Warren2017-06-06
| | | | | | | | | | | | | | | | | | nvgpu_log/info/warn/err() internally add a \n to the end of the message. Hence, callers should not include a \n at the end of the message. Doing so results in duplicate \n being printed, which ends up creating empty log messages. Remove the duplicate \n from all err/warn messages. (This message was updated in parallel with the previous change to fix this particular issue) Bug 1928311 Change-Id: I789f8c4b4084539ac901ed0f6b815518900cee90 Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-on: http://git-master/r/1495020 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

| | | | | | | | | | | | | | | | This function is an internal function to the VM manager that allocates virtual memory space in the GVA allocator. It is unfortunately used in the vGPU code, though. In any event, this patch cleans up and moves the implementation of these functions into the VM common code.

* gpu: nvgpu: Proper timeout for NVGPU_COND_WAITTerje Bergstrom2017-05-24
| | | | | | | | | | | | | | | | | | The timeout parameter to NVGPU_COND_WAIT() was passed directly to wait_event_timeout(), which takes jiffies. Also allows zero timeout to disable timeout. The return value of NVGPU_COND_WAIT() was defined in a way specific to how Linux wait_event_() calls work. Replace that with proper error reporting and change the callers to check against error codes.

Instead of including device.h wrap the debugfs init function with CONFIG_DEBUG_FS and forward declare struct device. We don't use any struct device internals here so we only need to let the compiler know that this type does exist.
