This patch adds the skeleton H/W debugger module support. This code enables registration and unregistration of a single HSA process at a time. The module saves the process's pasid and use it to verify that only the registered process is allowed to execute debugger operations through the kernel driver. v2: rename get_dbgmgr_mutex to kfd_get_dbgmgr_mutex to namespace it Signed-off-by:

This patch adds support for static user-mode queues in QCM. Queues which are designated as static can NOT be preempted by the CP microcode when it is executing its scheduling algorithm. This is needed for supporting the debugger feature, because we can't allow the CP to preempt queues which are currently being debugged. The number of queues that can be designated as static is limited by the number of HQDs (Hardware Queue Descriptors). Signed-off-by:

This patch adds four new IOCTLs to amdkfd. These IOCTLs expose a H/W debugger functionality to the userspace. The IOCTLs are: - AMDKFD_IOC_DBG_REGISTER: The purpose of this IOCTL is to notify amdkfd that a process wants to use GPU debugging facilities on itself only. It is expected that this IOCTL would be called before any other H/W debugger requests are sent to amdkfd and for each GPU where the H/W debugging needs to be enabled. The use of this IOCTL ensures that only one instance of a debugger is active in the system. - AMDKFD_IOC_DBG_UNREGISTER: This IOCTL detaches the debugger/debugged process from the H/W Debug which was established by the AMDKFD_IOC_DBG_REGISTER IOCTL. - AMDKFD_IOC_DBG_ADDRESS_WATCH: This IOCTL allows to set different watchpoints with various conditions as indicated by the IOCTL's arguments. The available number of watchpoints is retrieved from topology. This operation is confined to the current debugged process, which was registered through AMDKFD_IOC_DBG_REGISTER. - AMDKFD_IOC_DBG_WAVE_CONTROL: This IOCTL allows to control a wavefront as indicated by the IOCTL's arguments. For example, you can halt/resume or kill either a single wavefront or a set of wavefronts. This operation is confined to the current debugged process, which was registered through AMDKFD_IOC_DBG_REGISTER. Because the arguments for the address watch IOCTL and wave control IOCTL are dynamic, meaning that they could vary in size, the userspace passes a pointer to a structure (in userspace) that contains the value of the arguments. The kernel driver is responsible to parse this structure and validate its contents. v2: change void* to uint64_t inside ioctl arguments Signed-off-by:

Without this frontbuffer flip when enabling planes PSR got compromised and wasn't being enabled waiting forever on the flush that never arrived. Another solution would to create a enable_cursor function and split this frontbuffer flip among the different plane enable and disable functions. But if necessary this can be done in a follow up work. For now let's just fix the regression. It was removed by: commit 87d4300a Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Tue Apr 21 17:12:54 2015 +0300 drm/i915: Move intel_(pre_disable/post_enable)_primary to intel_display.c, and use it there.

This patch deinlines indirect register accessor functions. These functions perform two mmio accesses, framed by spin lock/unlock.

This commit is the "sink CRC" version of: commit 8c740dce Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date: Fri Oct 17 18:42:03 2014 -0300 drm/i915: disable IPS while getting the pipe CRCs. For some unknown reason, when IPS gets enabled, the sink CRC changes. Since hsw_enable_ips() doesn't really guarantee to enable IPS (it depends on package C-states), we can't really predict if IPS is enabled or disabled while running our CRC tests, so let's just completely disable IPS while sink CRCs are being used. If we find a way to make IPS not change the pipe CRC result, we may want to fix IPS and then revert this patch (and 8c740dce too). While this doesn't happen, let's merge this patch, so the IGT tests relying on sink CRCs can work properly. This was discovered while developing a new IGT test, which will probably be called kms_frontbuffer_tracking.

In commit 1854d5ca Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Apr 7 16:20:32 2015 +0100 drm/i915: Deminish contribution of wait-boosting from clients we removed an atomic timer based check for allowing waitboosting and moved it below the mutex taken during RPS. However, that mutex can be held for long periods of time on Vallyview/Cherryview as communication with the PCU is slow. As clients may frequently wait for results (e.g. such as tranform feedback) we introduced contention between the client and the RPS worker. We can take advantage of the RPS worker, by switching the wait boost decision to use spin locks and defer the actual reclocking to the worker. Fixes a regression of up to 45% on Baytrail and Baswell! v2 (Daniel): - Use max_freq_softlimit instead of the not-yet-merged boost frequency. - Don't inject a fake irq into the boost work, instead treat client_boost as just another legit waker. v3: Drop the now unused mask (Chris).
