Whenever we are running in the kernel with traps + * enabled, we decrement pcb_uw for each ``push'' of a CPU + * register window into the stack, and we increment it for + * each ``pull'' from the stack into the CPU. (If traps are + * disabled, or if we are in user mode, pcb_uw is junk.) + * + * To ease computing pcb_uw on traps from user mode, we keep track + * of the log base 2 of the single bit that is set in %wim. + * + * If an overflow occurs while the associated user stack pages + * are invalid (paged out), we have to store the registers + * in a page that is locked in core while the process runs, + * i.e., right here in the pcb. We also need the stack pointer + * for the last such window (but only the last, as the others + * are in each window) and the count of windows saved. We + * cheat by having a whole window structure for that one %sp. + * Thus, to save window pcb_rw[i] to memory, we write it at + * pcb_rw[i + 1].rw_in[6]. + * + * pcb_nsaved has three `kinds' of values. If 0, it means no + * registers are in the PCB (though if pcb_uw is positive, + * there may be the next time you look). If positive, it means + * there are no user registers in the CPU, but there are some + * saved in pcb_rw[]. As a special case, traps that needed + * assistance to pull user registers from the stack also store + * the registers in pcb_rw[], and set pcb_nsaved to -1. This + * special state is normally short-term: it can only last until the + * trap returns, and it can never persist across entry to user code. + */ +/* + * v9 addendum: + * + * Window handling between v8 and v9 has changed somewhat. There + * is no %wim. Instead, we have a %cwp, %cansave, %canrestore, + * %cleanwin, and %otherwin. By definition: + * + * %cansave + %canrestore + %otherwin = NWINDOWS - 2 + * + * In addition, %cleanwin >= %canrestore since restorable windows + * are considered clean. This means that by storing %canrestore + * and %otherwin, we should be able to compute the values of all + * the other registers. + * + * The only other register we need to save is %cwp because it cannot + * be trivially computed from the other registers. The %cwp is + * stored in the %tstate register, but if the machine was in a register + * window spill/fill handler, the value of that %cwp may be off by + * as much as 2 register windows. We will also store %cwp. [We will + * try to steal pcb_uw or pcb_nsaved for this purpose eventually.] + * + * To calculate what registers are in the pcb, start with pcb_cwp + * and proceed to (pcb_cwp - pcb_canrestore) % NWINDOWS. These should + * be saved to their appropriate register windows. The client routine + * (trap handler) is responsible for saving pcb_cwp + 1 [%o1-%o7] in + * the trap frame or on the stack. + * + * + * Even more addendum: + * + * With the new system for keeping track of register windows we don't + * care about anything other than pcb_uw which keeps track of how many + * full windows we have. As soon as a flush traps, we dump all user + * windows to the pcb, handle the fault, then restore all user windows. + * + * XXX we are using pcb_nsaved as the counter. pcb_uw is still a mask. + * change this as soon as the new scheme is debugged. + */ +struct pcb { + u_int64_t pcb_sp; /* sp (%o6) when switch() was called */ + u_int64_t pcb_pc; /* pc (%o7) when switch() was called */ + caddr_t pcb_onfault; /* for copyin/out */ + short pcb_pstate; /* %pstate when switch() was called -- may be useful if we support multiple memory models */ + char pcb_nsaved; /* number of windows saved in pcb */ + + /* The rest is probably not needed except for pcb_rw */ + char pcb_cwp; /* %cwp when switch() was called */ + char pcb_pil; /* %pil when switch() was called -- prolly not needed */ + + const char *lastcall; /* DEBUG -- name of last system call */ + /* the following MUST be aligned on a 64-bit boundary */ + struct rwindow64 pcb_rw[PCB_MAXWIN]; /* saved windows */ +}; + +/* + * The pcb is augmented with machine-dependent additional data for + * core dumps.
