| |
Hi,
Commit 66759a01adbfe8828dd063e32cf5ed3f46696181 added two new command-line options, IIUC:
disable_timer_pin_1: used to disable PIN 1 of the APIC timer, only had real effect on non-ATI chipsets, becuase the commit also added code to disable the PIN automatically on ATI chipsets
enable_timer_pin_1: used to enable PIN 1 of the APIC timer, only had real effect on ATI chipsets, where the PIN was automatically disabled.
But commit 1619cca2921f6927f4240e03f413d4165c7002fc removed the automatic detection of ATI chipsets, so think "enable_timer_pin_1" is useless now.
This patch removes it, completing the work of the last commit.
