From 958b7c80507a6eb847777b0d6d99d2cad08c529c Mon Sep 17 00:00:00 2001 From: Sam bobroff Date: Thu, 8 Oct 2015 11:50:23 +1100 Subject: powerpc/xmon: Paged output for paca display The paca display is already more than 24 lines, which can be problematic if you have an old school 80x24 terminal, or more likely you are on a virtual terminal which does not scroll for whatever reason. This patch adds a new command "#", which takes a single (hex) numeric argument: lines per page. It will cause the output of "dp" and "dpa" to be broken into pages, if necessary. Sample output: 0:mon> # 10 0:mon> dp1 paca for cpu 0x1 @ c00000000fdc0480: possible = yes present = yes online = yes lock_token = 0x8000 (0x8) paca_index = 0x1 (0xa) kernel_toc = 0xc000000000eb2400 (0x10) kernelbase = 0xc000000000000000 (0x18) kernel_msr = 0xb000000000001032 (0x20) emergency_sp = 0xc00000003ffe8000 (0x28) mc_emergency_sp = 0xc00000003ffe4000 (0x2e0) in_mce = 0x0 (0x2e8) data_offset = 0x7f170000 (0x30) hw_cpu_id = 0x8 (0x38) cpu_start = 0x1 (0x3a) kexec_state = 0x0 (0x3b) [Hit a key (a:all, q:truncate, any:next page)] 0:mon> __current = 0xc00000007e696620 (0x290) kstack = 0xc00000007e6ebe30 (0x298) stab_rr = 0xb (0x2a0) saved_r1 = 0xc00000007ef37860 (0x2a8) trap_save = 0x0 (0x2b8) soft_enabled = 0x0 (0x2ba) irq_happened = 0x1 (0x2bb) io_sync = 0x0 (0x2bc) irq_work_pending = 0x0 (0x2bd) nap_state_lost = 0x0 (0x2be) 0:mon> Signed-off-by: Sam Bobroff [mpe: Use bool, make some variables static] Signed-off-by: Michael Ellerman --- arch/powerpc/xmon/nonstdio.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'arch/powerpc/xmon/nonstdio.h') diff --git a/arch/powerpc/xmon/nonstdio.h b/arch/powerpc/xmon/nonstdio.h index 18a51de..f865336 100644 --- a/arch/powerpc/xmon/nonstdio.h +++ b/arch/powerpc/xmon/nonstdio.h @@ -3,6 +3,9 @@ #define printf xmon_printf #define putchar xmon_putchar +extern void xmon_set_pagination_lpp(unsigned long lpp); +extern void xmon_start_pagination(void); +extern void xmon_end_pagination(void); extern int xmon_putchar(int c); extern void xmon_puts(const char *); extern char *xmon_gets(char *, int); -- cgit v1.1
