| /* A PDump out2.txt script is made up of 3 sections from three buffers: |
| * * |
| * - Init phase buffer - holds PDump data written during driver |
| * initialisation, non-volatile. |
| * - Main phase buffer - holds PDump data written after driver init, |
| * volatile. |
| * - Deinit phase buffer - holds PDump data needed to shutdown HW/play back, |
| * written only during driver initialisation using |
| * the DEINIT flag. |
| * |
| * Volatile in this sense means that the buffer is drained and cleared when |
| * the pdump capture application connects and transfers the data to file. |
| * |
| * The PDump sub-system uses the driver state (init/post-init), whether |
| * the pdump capture application is connected or not (capture range set/unset) |
| * and, if pdump connected whether the frame is in the range set, to decide |
| * which of the 3 buffers to write the PDump data. Hence there are several |
| * key time periods in the lifetime of the kernel driver that is enabled |
| * with PDUMP=1 (flag XX labels below time line): |
| * |
| * Events:load init pdump enter exit pdump |
| * driver done connects range range disconnects |
| * |__________________|____________|__________|______________|____________|______ . . . |
| * State: | init phase | no capture | <- capture client connected -> | no capture |
| * | | | | |
| * |__________________|____________|______________________________________|_____ . . . |
| * Flag: | CT,DI | NONE,CT,PR | NONE,CT,PR | See no |
| * | Never NONE or PR | Never DI | Never DI | capture |
| * |__________________|____________|______________________________________|_____ . . . |
| * Write | NONE -undef | -No write | -No write | -Main buf | -No write | See no |
| * buffer | CT -Init buf | -Main buf | -Main buf | -Main buf | -Main buf | capture |
| * | PR -undef | -Init buf | -undef | -Init & Main | -undef | |
| * | DI -Deinit buf | -undef | -undef | -undef | -undef | |
| * |__________________|____________|___________|______________|___________|_____ . . . |
| * |
| * Note: The time line could repeat if the pdump capture application is |
| * disconnected and reconnected without unloading the driver module. |
| * |
| * The DEINIT (DI) | CONTINUOUS (CT) | PERSISTENT (PR) flags must never |
| * be OR'd together and given to a PDump call since undefined behaviour may |
| * result and produce an invalid PDump which does not play back cleanly. |
| * |
| * The decision on which flag to use comes down to which time period the |
| * client or server driver makes the PDump write call AND the nature/purpose |
| * of the data. |
| * |
| * Note: This is a simplified time line, not all conditions represented. |
