2 * Some macros to handle stack frames in assembly. 2
3 x86 function call convention, 64-bit:
4 -------------------------------------
5 arguments | callee-saved | extra caller-saved | return
6 [callee-clobbered] | | [callee-clobbered] |
7 ---------------------------------------------------------------------------
8 rdi rsi rdx rcx r8-9 | rbx rbp [*] r12-15 | r10-11 | rax, rdx [**]
9
10 ( rsp is obviously invariant across normal function calls. (gcc can 'merge'
11 functions when it sees tail-call optimization possibilities) rflags is
12 clobbered. Leftover arguments are passed over the stack frame.)
13
14 [*] In the frame-pointers case rbp is fixed to the stack frame.
15
16 [**] for struct return values wider than 64 bits the return convention is a
17 bit more complex: up to 128 bits width we return small structures
18 straight in rax, rdx. For structures larger than that (3 words or
19 larger) the caller puts a pointer to an on-stack return struct
20 [allocated in the caller's stack frame] into the first argument - i.e.
21 into rdi. All other arguments shift up by one in this case.
22 Fortunately this case is rare in the kernel.
23
24For 32-bit we have the following conventions - kernel is built with
25-mregparm=3 and -freg-struct-return:
26
27 x86 function calling convention, 32-bit:
28 ----------------------------------------
29 arguments | callee-saved | extra caller-saved | return
30 [callee-clobbered] | | [callee-clobbered] |
31 -------------------------------------------------------------------------
32 eax edx ecx | ebx edi esi ebp [*] | <none> | eax, edx [**]
33
34 ( here too esp is obviously invariant across normal function calls. eflags
35 is clobbered. Leftover arguments are passed over the stack frame. )
36
37 [*] In the frame-pointers case ebp is fixed to the stack frame.
38
39 [**] We build with -freg-struct-return, which on 32-bit means similar
40 semantics as on 64-bit: edx can be used for a second return value
41 (i.e. covering integer and structure sizes up to 64 bits) - after that
42 it gets more complex and more expensive: 3-word or larger struct returns
43 get done in the caller's frame and the pointer to the return struct goes
44 into regparm0, i.e. eax - the other arguments shift up and the
45 function's register parameters degenerate to regparm=2 in essence.

5 * Linux IRQ vector layout.
6 *
7 * There are 256 IDT entries (per CPU - each entry is 8 bytes) which can
8 * be defined by Linux. They are used as a jump table by the CPU when a
9 * given vector is triggered - by a CPU-external, CPU-internal or
10 * software-triggered event.
11 *
12 * Linux sets the kernel code address each entry jumps to early during
13 * bootup, and never changes them. This is the general layout of the
14 * IDT entries:
15 *
16 * Vectors 0 ... 31 : system traps and exceptions - hardcoded events
17 * Vectors 32 ... 127 : device interrupts
18 * Vector 128 : legacy int80 syscall interface
19 * Vectors 129 ... 237 : device interrupts
20 * Vectors 238 ... 255 : special interrupts
21 *
22 * 64-bit x86 has per CPU IDT tables, 32-bit has one shared IDT table.
23 *
24 * This file enumerates the exact layout of them:

2 * GCC stack protector support.
3 *
4 * Stack protector works by putting predefined pattern at the start of
5 * the stack frame and verifying that it hasn't been overwritten when
6 * returning from the function. The pattern is called stack canary
7 * and unfortunately gcc requires it to be at a fixed offset from %gs.
8 * On x86_64, the offset is 40 bytes and on x86_32 20 bytes. x86_64
9 * and x86_32 use segment registers differently and thus handles this
10 * requirement differently.
11 *
12 * On x86_64, %gs is shared by percpu area and stack canary. All
13 * percpu symbols are zero based and %gs points to the base of percpu
14 * area. The first occupant of the percpu area is always
15 * irq_stack_union which contains stack_canary at offset 40. Userland
16 * %gs is always saved and restored on kernel entry and exit using
17 * swapgs, so stack protector doesn't add any complexity there.
18 *
19 * On x86_32, it's slightly more complicated. As in x86_64, %gs is
20 * used for userland TLS. Unfortunately, some processors are much
21 * slower at loading segment registers with different value when
22 * entering and leaving the kernel, so the kernel uses %fs for percpu
23 * area and manages %gs lazily so that %gs is switched only when
24 * necessary, usually during task switch.
25 *
26 * As gcc requires the stack canary at %gs:20, %gs can't be managed
27 * lazily if stack protector is enabled, so the kernel saves and
28 * restores userland %gs on kernel entry and exit. This behavior is
29 * controlled by CONFIG_X86_32_LAZY_GS and accessors are defined in
30 * system.h to hide the details.
