[LinuxBIOS] The device number of PCIe

Hi, all, In PCI, the IDSEL pin defines the device number. But in PCIe, there is no such pin, how is the device number defined? Best Regards 丰立波 Feng Libo @ AMD Ext: 20906 Mobile Phone: 13683249071 Office Phone: 0086-010-62801406 -- linuxbios mailing list linuxbios@linuxbios.org http

[LinuxBIOS] NVRAM

Hi, all, Is this possible that the FLASH memory containing BIOS code can be partly saved for NVRAM? Programming FLASH chip is not as easy and fast as RAM, but it is larger and holds data for ever. Best Regards 丰立波 Feng Libo @ AMD Ext: 20906 Mobile Phone: 13683249071 Office Phone: 0086-010

Re: [LinuxBIOS] Interesting.

Hi, all, But the function init_cpus is called before the three functions: w83627hf_enable_serial(SERIAL_DEV, TTYS0_BASE); uart_init(); console_init(); The trace is sent out from the init_cpus. Best Regards 丰立波 Feng Libo @ AMD Ext: 20906 Mobile Phone: 13683249071 Office Phone: 0086-010

[LinuxBIOS] Interesting.

Hi, all, In our board, we found the trace is sent out: "Issuing SOFT_RESET…" from the function init_cpus in the file init_cpus.c. But when the function runs, the serial port is still far to be initialized, how dose the trace is sent out? Best Regards 丰立波 Feng Libo @ AMD Ext: 20

Re: [LinuxBIOS] IRQ question

. So the idea led me to a wrong direction. The file io_apic.c under arch/i386/kernel tells me all secret: the function assign_irq_vector(irq), as its name, assigns a vector to an IRQ of APIC. == Best Regards ??? Feng Libo @ AMD

[LinuxBIOS] IRQ question

Hi, all, A simple question: when talking about IRQ, you mean one of the 256 interrupt vectors within x86, or one of the pins of APIC, or one of the pins of 8259? I always got confused by it. Best Regards 丰立波 Feng Libo @ AMD Ext: 20906 Mobile Phone: 13683249071 Office Phone: 0086-010

Re: [LinuxBIOS] Read SPD issue

Generally, I2C mux has some external pins to set its address. In my Tyan S3992, the address is 0x71, so the function activate_spd_rom is called before accessing SPD. Best Regards ??? Feng Libo @ AMD Ext: 20906 Mobile Phone: 13683249071 Office Phone: 0086-010-62801406 -Original Message

[LinuxBIOS] How many tables exist in BIOS?
