Red Hat Bugzilla – Bug 344791
[RFE] memtest86+ allow runtime configuration of serial port/options
Last modified: 2014-06-18 04:00:39 EDT
This would be exactly identical to Bug #319631 for RHEL4.7, except compiled with a different gcc version. Does this mean that we have to do QA twice? +++ This bug was initially created as a clone of Bug #319631 +++ Escalated to Bugzilla from IssueTracker -- Additional comment from tao@redhat.com on 2007-10-04 21:36 EST -- We would like the ability to run memtest86+ on serial consoles reliably. However the serial console device and baud rate are compile time options (set in config.h and serial.h) so we are having to compile many versions and configure the appropriate one. Currently we are building the following. Making the serial device and baudrate a parameter on the grub.conf line would be the most flexible solution IMHO. memtest86+.vga memtest86+.9600.ttyS1 memtest86+.9600.ttyS0 memtest86+.19200.ttyS1 memtest86+.19200.ttyS0 memtest86+.115200.ttyS1 memtest86+.115200.ttyS0 To use ttyS1, you need to do the following. $ diff -u serial.h.ttyS0 serial.h.ttyS1 --- serial.h.ttyS0 2007-10-01 11:12:41.000000000 -0400 +++ serial.h.ttyS1 2007-10-01 11:13:07.000000000 -0400 @@ -136,8 +136,8 @@ */ #include "io.h" -#define serial_echo_outb(v,a) outb((v),(a)+0x3f8) -#define serial_echo_inb(a) inb((a)+0x3f8) +#define serial_echo_outb(v,a) outb((v),(a)+0x2f8) +#define serial_echo_inb(a) inb((a)+0x2f8) #define BOTH_EMPTY (UART_LSR_TEMT | UART_LSR_THRE) /* Wait for transmitter & holding register to empty */ #define WAIT_FOR_XMITR \\ This event sent from IssueTracker by tdunnon [SEG - Feature Request] issue 133769 -- Additional comment from mschmidt@redhat.com on 2007-10-17 12:27 EST -- Created an attachment (id=230041) patch series providing the requested functionality This is a patch series I sent upstream.

requires memtest86+ package update to the version 2.00 or newer.
This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unfortunately unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux.
The bug is likely to be rejected for the whole EL5 lifetime, because it doesn't conform to any criteria. Safe to close.
