| * drm/amdkfd: Enforce kill all waves on process terminationBen Goz2015-06-03
| | | | | | | | | | | | | | | | | | | | | | | | This commit makes sure that on process termination, after we're destroying all the active queues, we're killing all the existing wave front of the current process. By doing this we're making sure that if any of the CUs were blocked by infinite loop we're enforcing it to end the shader explicitly.

| * drm/amdkfd: Add static user-mode queues supportYair Shachar2015-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| * drm/amdkfd: add H/W debugger IOCTL set definitionsYair Shachar2015-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Yair Shachar <yair.shachar@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

This parameter specifies whether amdkfd should send the SIGTERM signal to an HSA process, when the following conditions occur: 1. The GPU triggers an exception regarding a kernel that was issued by this process. 2. The HSA process isn't waiting on an event that handles this exception. The default behavior is not to send a SIGTERM and suffice with a dmesg error print. Reviewed-by: Ben Goz <ben.goz@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com>

The amdkfd interrupt module maintains an internal interrupt ring per amdkfd device. The internal interrupt ring contains interrupts that needs further handling. The extra handling is deferred to a later time through a workqueue. There's no acknowledgment for the interrupts we use. The hardware simply queues a new interrupt each time without waiting. The fixed-size internal queue means that it's possible for us to lose interrupts because we have no back-pressure to the hardware. However, only interrupts that are "wanted" by amdkfd, are copied into the amdkfd s/w interrupt ring, in order to minimize the chances for overflow of the ring.

| * drm/amdkfd: Preserve CP_MQD_IQ_RPTR internal stateJay Cornwall2015-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | CP microcode uses undocumented bits in this register to record queue state information. The KFD zeroes these bits in update_mqd, when invoked through the UPDATE_QUEUE ioctl, causing incoherent state when the ioctl is used to successively unmap and map a queue. Since the queue type cannot be changed in this path, move the MQD write to init_mqd.

| * drm/amdkfd: Fix dqm->queue_count trackingJay Cornwall2015-01-19
| | | | | | | | | | | | | | | | | | | | dqm->queue_count tracks queues in the active state only. In a few places this count is modified unconditionally, leading to an incorrect value when the UPDATE_QUEUE ioctl is used to make a queue inactive.
