2250  * driver to run the "restore" phase explicitly
2251  *
2252  * Goya/Gaudi:
2253  * There are two types of queues - external and internal. External queues
2254  * are DMA queues which transfer data from/to the Host. All other queues are

2256  * on JOBS which are enqueued in the external queues.

2259  * There is a single type of queue for all types of engines, either DMA engines
2260  * for transfers from/to the host or inside the device, or compute engines.
2261  * The driver will get completion notifications from the device for all queues.
2262  *
2263  * For jobs on external queues, the user needs to create command buffers
2264  * through the CB ioctl and give the CB's handle to the CS ioctl. For jobs on
2265  * internal queues, the user needs to prepare a "command buffer" with packets
2266  * on either the device SRAM/DRAM or the host, and give the device address of
2267  * that buffer to the CS ioctl.
2268  * For jobs on H/W queues both options of command buffers are valid.
2269  *
2270  * This IOCTL is asynchronous in regard to the actual execution of the CS. This
2271  * means it returns immediately after ALL the JOBS were enqueued on their
2272  * relevant queues. Therefore, the user mustn't assume the CS has been completed
2273  * or has even started to execute.
2274  *
2275  * Upon successful enqueue, the IOCTL returns a sequence number which the user
2276  * can use with the "Wait for CS" IOCTL to check whether the handle's CS
2277  * non-internal JOBS have been completed. Note that if the CS has internal JOBS
2278  * which can execute AFTER the external JOBS have finished, the driver might
2279  * report that the CS has finished executing BEFORE the internal JOBS have
2280  * actually finished executing.
2281  *
2282  * Even though the sequence number increments per CS, the user can NOT
2283  * automatically assume that if CS with sequence number N finished, then CS
2284  * with sequence number N-1 also finished. The user can make this assumption if
2285  * and only if CS N and CS N-1 are exactly the same (same CBs for the same

2340  * Debug
2341  * - Enable/disable the ETR/ETF/FUNNEL/STM/BMON/SPMU debug traces
2342  *
2343  * This IOCTL allows the user to get debug traces from the chip.
2344  *
2345  * Before the user can send configuration requests of the various
2346  * debug/profile engines, it needs to set the device into debug mode.
2347  * This is because the debug/profile infrastructure is shared component in the
2348  * device and we can't allow multiple users to access it at the same time.
2349  *
2350  * Once a user set the device into debug mode, the driver won't allow other
2351  * users to "work" with the device, i.e. open a FD. If there are multiple users
2352  * opened on the device, the driver won't allow any user to debug the device.
2353  *
2354  * For each configuration request, the user needs to provide the register index
2355  * and essential data such as buffer address and size.
2356  *
2357  * Once the user has finished using the debug/profile engines, he should
2358  * set the device into non-debug mode, i.e. disable debug mode.
2359  *
2360  * The driver can decide to "kick out" the user if he abuses this interface.
