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 <sam.bobroff@au1.ibm.com> [mpe: Use bool, make some variables static] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
