M5135 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-questions@freebsd.org X-Loop: FreeBSD.ORG Dear sir, Several month ago, one of our customers name Iwill feedback one question: FreeBSD 2.2.5 can not found UART port at Iwill motherboard (use Acer labs. M5135). This parts is use Intel new technology name--serial IRQ. and did not found any problem in the other parts such as M5113,M5123 AND M1543. And our R&D people made much effort to study how FreeBSD can not found UART and Tape out a new version to fixed this issue(for 2.2.5). But after we get the new chip we still have got the following issue: 1. FreeBSD boot from CD-ROM PASS 2. FreeBSD boot from HDD PASS 3 FreeBSD boot from FDD FAIL After we studied the different between boot from CD-ROM,HDD AND FDD we found the different is in the command and command recovery time when FreeBSD polling UART's IRQ(read IIR register 2fa,3fa,2ea,3ea). The recovery time of CD-ROM,HDD is around several us but FDD command recovery time only 2us. would it possible last the FDD commend recovery time to over 10us? Maybe Serial IRQ will take more time when set IIR register and read 8259 to get the status, so we recommend OS polling or read those IIR register it is better to last the recovery time to get the 8259 IRQ status. Another issue is read 8259 IRQ status method, in the parallel IRQ you can read from edge or level but NEW serial IRQ our chip M5135 only have got a pulse and not the level. Maybe this is why FreeBSD can not found UART. Our new chip had been option to change the IRQ from pulse to level, but in FDD boot still have this issue. Do you have any comments? And FreeBSD test have been put in our chip verify item, so if you release new version, please mail to us for testting. If you have any comments please contact me: johnson@ali.com.tw Thanks JOHNSON CHEN / MANAGER Acer Labs.
