From 42355cb73049ee7a4af0f539a2a5b7d4ee1abc65 Mon Sep 17 00:00:00 2001 From: Bruce Ashfield Date: Fri, 7 May 2021 12:22:57 -0400 Subject: [PATCH] linux-yocto/5.4: qemuppc32: reduce serial shutdown issues Integrating the following commit(s) to linux-yocto/5.4: qemuppc32: reduce serial issues seen on shutdown Richard reported: We've been seeing a lot of the qemuppc shutdown issue and I decided to look into it. The really worrying thing looking at the logs locally is the serial ports are showing irq issues and becoming disabled as nobody would handle them. Errors like: [ 9.194886] irq 36: nobody cared (try booting with the "irqpoll" option) [ 9.198712] CPU: 0 PID: 127 Comm: bootlogd Not tainted [ 9.202283] Call Trace: [ 9.205611] [d1005f00] [c00a0da8] __report_bad_irq+0x50/0x138 (unreliable) [ 9.209347] [d1005f30] [c00a0cc0] note_interrupt+0x324/0x378 [ 9.212855] [d1005f70] [c009d138] handle_irq_event+0xe8/0x104 [ 9.216353] [d1005fa0] [c00a1d9c] handle_fasteoi_irq+0xc0/0x29c [ 9.219960] [d1005fc0] [c009b798] generic_handle_irq+0x40/0x5c [ 9.223496] [d1005fd0] [c00075d0] __do_irq+0x58/0x188 [ 9.226948] [d1005ff0] [c0010040] call_do_irq+0x20/0x38 [ 9.230391] [d29eda60] [c0007788] do_IRQ+0x88/0xfc [ 9.233860] [d29eda90] [c0016454] ret_from_except+0x0/0x14 [ 9.237288] --- interrupt: 501 at __setup_irq+0x3c4/0x838 [ 9.237288] LR = __setup_irq+0x790/0x838 [ 9.244155] [d29edb88] [c009f0a4] request_threaded_irq+0x114/0x1c8 [ 9.247672] [d29edbb8] [c07a5a18] pmz_startup+0x17c/0x32c [ 9.251203] [d29edbd8] [c07a1140] uart_port_startup+0x184/0x2f8 [ 9.254651] [d29edc08] [c07a1974] uart_port_activate+0x78/0xf4 [ 9.258141] [d29edc28] [c07839f8] tty_port_open+0xd4/0x170 [ 9.261579] [d29edc58] [c079db74] uart_open+0x2c/0x48 [ 9.265116] [d29edc68] [c077a288] tty_open+0x168/0x640 [ 9.268574] [d29edcd8] [c0280be8] chrdev_open+0x138/0x2a4 [ 9.272123] [d29edd18] [c027421c] do_dentry_open+0x228/0x410 [ 9.275643] [d29edd48] [c028e9f4] path_openat+0xb04/0xf28 [ 9.279184] [d29eddd8] [c02917e4] do_filp_open+0x120/0x164 [ 9.282535] [d29ede98] [c0276238] do_sys_openat2+0xd8/0x19c [ 9.285790] [d29edee8] [c0276574] sys_openat+0x88/0xdc [ 9.289096] [d29edf38] [c00160d8] ret_from_syscall+0x0/0x34 [ 9.292620] --- interrupt: c01 at 0xfec3738 [ 9.292620] LR = 0xfec36e0 [ 9.299035] handlers: [ 9.302312] [<7f7f7da8>] pmz_interrupt [ 9.305541] Disabling IRQ #36 (and the irqpoll option does not help) This is problematic as the shutdown test uses the serial interface to shut down the system. If the serial interface fails to login or run the command, game over for the test. CONFIG_SERIAL_PMACZILOG_CONSOLE complicates that handling, but doesn't provide any output or capabilities that we need. So we disable it here, and reduce the chances of issues during shutdown.
