35501 ! This file contains the assembler startup code for Minix and the 32-bit
35502 ! interrupt handlers. It cooperates with start.c to set up a good
35503 ! environment for main().
35504
35505 ! This file is part of the lowest layer of the MINIX kernel. The other part
35506 ! is "proc.c". The lowest layer does process switching and message handling.
35507
35508 ! Every transition to the kernel goes through this file. Transitions are
35509 ! caused by sending/receiving messages and by most interrupts. (RS232
35510 ! interrupts may be handled in the file "rs2.s" and then they rarely enter
35511 ! the kernel.)
35512
35513 ! Transitions to the kernel may be nested. The initial entry may be with a
35514 ! system call, exception or hardware interrupt; reentries may only be made
35515 ! by hardware interrupts. The count of reentries is kept in "k_reenter".
35516 ! It is important for deciding whether to switch to the kernel stack and
35517 ! for protecting the message passing code in "proc.c".
35518
35519 ! For the message passing trap, most of the machine state is saved in the
35520 ! proc table. (Some of the registers need not be saved.) Then the stack is
35521 ! switched to "k_stack", and interrupts are reenabled. Finally, the system
35522 ! call handler (in C) is called. When it returns, interrupts are disabled
35523 ! again and the code falls into the restart routine, to finish off held-up
35524 ! interrupts and run the process or task whose pointer is in "proc_ptr".
35525
35526 ! Hardware interrupt handlers do the same, except (1) The entire state must
35527 ! be saved. (2) There are too many handlers to do this inline, so the save
35528 ! routine is called. A few cycles are saved by pushing the address of the
35529 ! appropiate restart routine for a return later. (3) A stack switch is
35530 ! avoided when the stack is already switched. (4) The (master) 8259 interrupt
35531 ! controller is reenabled centrally in save(). (5) Each interrupt handler
35532 ! masks its interrupt line using the 8259 before enabling (other unmasked)
35533 ! interrupts, and unmasks it after servicing the interrupt. This limits the
35534 ! nest level to the number of lines and protects the handler from itself.
35535
35536 ! For communication with the boot monitor at startup time some constant
35537 ! data are compiled into the beginning of the text segment. This facilitates
35538 ! reading the data at the start of the boot process, since only the first
35539 ! sector of the file needs to be read.
35540
35541 ! Some data storage is also allocated at the end of this file. This data
35542 ! will be at the start of the data segment of the kernel and will be read
35543 ! and modified by the boot monitor before the kernel starts.

36100 #
36101 ! This file contains the assembler startup code for Minix and the 16-bit
36102 ! interrupt handlers. It cooperates with cstart.c to set up a good
36103 ! environment for main().
36104
36105 ! This file is part of the lowest layer of the MINIX kernel. The other part
36106 ! is "proc.c". The lowest layer does process switching and message handling.
36107
36108 ! Every transition to the kernel goes through this file. Transitions are
36109 ! caused by sending/receiving messages and by most interrupts. (RS232
36110 ! interrupts may be handled in the file "rs2.s" and then they rarely enter
36111 ! the kernel.)
36112
36113 ! Transitions to the kernel may be nested. The initial entry may be with a
36114 ! system call, exception or hardware interrupt; reentries may only be made
36115 ! by hardware interrupts. The count of reentries is kept in "k_reenter".
36116 ! It is important for deciding whether to switch to the kernel stack and
36117 ! for protecting the message passing code in "proc.c".
36118
36119 ! For the message passing trap, most of the machine state is saved in the
36120 ! proc table. (Some of the registers need not be saved.) Then the stack is
36121 ! switched to "k_stack", and interrupts are reenabled. Finally, the system
36122 ! call handler (in C) is called. When it returns, interrupts are disabled
36123 ! again and the code falls into the restart routine, to finish off held-up
36124 ! interrupts and run the process or task whose pointer is in "proc_ptr".
36125
36126 ! Hardware interrupt handlers do the same, except (1) The entire state must
36127 ! be saved. (2) There are too many handlers to do this inline, so the save
36128 ! routine is called. A few cycles are saved by pushing the address of the
36129 ! appropiate restart routine for a return later. (3) A stack switch is
36130 ! avoided when the stack is already switched. (4) The (master) 8259 interrupt
36131 ! controller is reenabled centrally in save(). (5) Each interrupt handler
36132 ! masks its interrupt line using the 8259 before enabling (other unmasked)
36133 ! interrupts, and unmasks it after servicing the interrupt. This limits the
36134 ! nest level to the number of lines and protects the handler from itself.
36135
36136 ! For communication with the boot monitor at startup time some constant
36137 ! data are compiled into the beginning of the text segment. This facilitates
36138 ! reading the data at the start of the boot process, since only the first
36139 ! sector of the file needs to be read.
36140
36141 ! Some data storage is also allocated at the end of this file. This data
36142 ! will be at the start of the data segment of the kernel and will be read
36143 ! and modified by the boot monitor before the kernel starts.
