+ * SPARC Process Control Block.
+ *
+ * pcb_uw is positive if there are any user windows that are
+ * are currently in the CPU windows rather than on the user
+ * stack. 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.
