-/**
- * @brief This file describes the API used by Gator to collect hardware counters data from a Mali device.
- */
-
-/* This define is used by the gator kernel module compile to select which DDK
- * API calling convention to use. If not defined (legacy DDK) gator assumes
- * version 1. The version to DDK release mapping is:
- *     Version 1 API: DDK versions r1px, r2px
- *     Version 2 API: DDK versions r3px, r4px
- *     Version 3 API: DDK version r5p0 and newer
- *
- * API Usage
- * =========
- *
- * 1] Call kbase_gator_hwcnt_init_names() to return the list of short counter
- * names for the GPU present in this device.
- *
- * 2] Create a kbase_gator_hwcnt_info structure and set the counter enables for
- * the counters you want enabled. The enables can all be set for simplicity in
- * most use cases, but disabling some will let you minimize bandwidth impact.
- *
- * 3] Call kbase_gator_hwcnt_init() using the above structure, to create a
- * counter context. On successful return the DDK will have populated the
- * structure with a variety of useful information.
- *
- * 4] Call kbase_gator_hwcnt_dump_irq() to queue a non-blocking request for a
- * counter dump. If this returns a non-zero value the request has been queued,
- * otherwise the driver has been unable to do so (typically because of another
- * user of the instrumentation exists concurrently).
- *
- * 5] Call kbase_gator_hwcnt_dump_complete() to test whether the  previously
- * requested dump has been succesful. If this returns non-zero the counter dump
- * has resolved, but the value of *success must also be tested as the dump
- * may have not been successful. If it returns zero the counter dump was
- * abandoned due to the device being busy (typically because of another
- * user of the instrumentation exists concurrently).
- *
- * 6] Process the counters stored in the buffer pointed to by ...
- *
- *        kbase_gator_hwcnt_info->kernel_dump_buffer
- *
- *    In pseudo code you can find all of the counters via this approach:
- *
- *
- *        hwcnt_info # pointer to kbase_gator_hwcnt_info structure
- *        hwcnt_name # pointer to name list
- *
- *        u32 * hwcnt_data = (u32*)hwcnt_info->kernel_dump_buffer
- *
- *        # Iterate over each 64-counter block in this GPU configuration
- *        for( i = 0; i < hwcnt_info->nr_hwc_blocks; i++) {
- *            hwc_type type = hwcnt_info->hwc_layout[i];
- *
- *            # Skip reserved type blocks - they contain no counters at all
- *            if( type == RESERVED_BLOCK ) {
- *                continue;
- *            }
- *
- *            size_t name_offset = type * 64;
- *            size_t data_offset = i * 64;
- *
- *            # Iterate over the names of the counters in this block type
- *            for( j = 0; j < 64; j++) {
- *                const char * name = hwcnt_name[name_offset+j];
- *
- *                # Skip empty name strings - there is no counter here
- *                if( name[0] == '\0' ) {
- *                    continue;
- *                }
- *
- *                u32 data = hwcnt_data[data_offset+j];
- *
- *                printk( "COUNTER: %s DATA: %u\n", name, data );
- *            }
- *        }
- *
- *
- *     Note that in most implementations you typically want to either SUM or
- *     AVERAGE multiple instances of the same counter if, for example, you have
- *     multiple shader cores or multiple L2 caches. The most sensible view for
- *     analysis is to AVERAGE shader core counters, but SUM L2 cache and MMU
- *     counters.
- *
- * 7] Goto 4, repeating until you want to stop collecting counters.
- *
- * 8] Release the dump resources by calling kbase_gator_hwcnt_term().
- *
- * 9] Release the name table resources by calling kbase_gator_hwcnt_term_names().
- *    This function must only be called if init_names() returned a non-NULL value.
