This - * is a problem when implementing sched_clock() for example, where a 64-bit - * non-wrapping monotonic value is expected to be returned. - * - * To overcome that limitation, let's extend a 32-bit counter to 63 bits - * in a completely lock free fashion. Bits 0 to 31 of the clock are provided - * by the hardware while bits 32 to 62 are stored in memory. The top bit in - * memory is used to synchronize with the hardware clock half-period. When - * the top bit of both counters (hardware and in memory) differ then the - * memory is updated with a new value, incrementing it when the hardware - * counter wraps around. - * - * Because a word store in memory is atomic then the incremented value will - * always be in synch with the top bit indicating to any potential concurrent - * reader if the value in memory is up to date or not with regards to the - * needed increment. And any race in updating the value in memory is harmless - * as the same value would simply be stored more than once. - * - * The only restriction for the algorithm to work properly is that this - * code must be executed at least once per each half period of the 32-bit - * counter to properly update the state bit in memory. This is usually not a - * problem in practice, but if it is then a kernel timer could be scheduled - * to manage for this code to be executed often enough. - * - * Note that the top bit (bit 63) in the returned value should be considered - * as garbage. It is not cleared here because callers are likely to use a - * multiplier on the returned value which can get rid of the top bit - * implicitly by making the multiplier even, therefore saving on a runtime - * clear-bit instruction.

For example, + * the MAC registers are described as offsets from the first + * MAC register, and there will be a MAC_REGISTER() macro + * to calculate the base address of a given MAC. + * + * The information in this file is based on the BCM1X55/BCM1X80 + * User Manual, Document 1X55_1X80-UM100-R, 22/12/03. + * + * This file is basically a "what's new" header file. Since the + * BCM1250 and the new BCM1480 (and derivatives) share many common + * features, this file contains only what's new or changed from + * the 1250. (above, you can see that we include the 1250 symbols + * to get the base functionality). + * + * In software, be sure to use the correct symbols, particularly + * for blocks that are different between the two chip families. + * All BCM1480-specific symbols have _BCM1480_ in their names, + * and all BCM1250-specific and "base" functions that are common in + * both chips have no special names (this is for compatibility with + * older include files). Therefore, if you're working with the + * SCD, which is very different on each chip, A_SCD_xxx implies + * the BCM1250 version and A_BCM1480_SCD_xxx implies the BCM1480 + * version. +

Directly after this is a + * copy of the task_struct, which is currently not used by gdb, + * but it may come in handy at some point. All of the registers + * are stored as part of the upage. The upage should always be + * only one page long. + * data: The data segment follows next. We use current->end_text to + * current->brk to pick up all of the user variables, plus any memory + * that may have been sbrk'ed. No attempt is made to determine if a + * page is demand-zero or if a page is totally unused, we just cover + * the entire range. All of the addresses are rounded in such a way + * that an integral number of pages is written. + * stack: We need the stack information in order to get a meaningful + * backtrace.
