PATCH 4/7 add a new serial port debug function

There is an existing serial port debug function: prom_putchar(), but it can only print one char, herein add a new prom_printf(), which works like printk, but print to serial port, which is very important to kernel debugging.

PATCH 5/7 add serial port support

This patch add serial port support for all of the existing loongson family machines. most of the board specific part are put in serial.c, and the base address of the serial ports are defined as macros in machine.h for sharing it between serial.c and early_printk.c

PATCH 6/7 remove reference from bonito64

There is a built-in northbridge in loongson2e/2f, which is bonito64 compatiable, but it differs from bonito64. to avoid influencing the original bonito64 support and make the loongson support more maintainable, it's better to remove reference from bonito64.

And this patch is a very important preparation for the coming loongson2f family machines' support, all the coming patches depend on it.

Re: [PATCH -queue 7/7] [loongson] fuloong2e: update config file

Quoted 3 lines · Wu Zhangjin

This patch enable Hibernation support by default, and choose SPARSEMEM memory model to avoid Hibernation failure with FLATMEM and also save memory wasted by FLATMEM.

Thanks, queued for 2.6.33.

Re: [PATCH -queue 6/7] [loongson] remove reference from bonito64

In reply to Wu Zhangjin

Quoted 7 lines · Wu Zhangjin

There is a built-in northbridge in loongson2e/2f, which is bonito64 compatiable, but it differs from bonito64. to avoid influencing the original bonito64 support and make the loongson support more maintainable, it's better to remove reference from bonito64.
And this patch is a very important preparation for the coming loongson2f family machines' support, all the coming patches depend on it.

Thanks, queued for 2.6.33.

Re: [PATCH -queue 5/7] [loongson] add serial port support

In reply to Wu Zhangjin

This patch add serial port support for all of the existing loongson family machines. most of the board specific part are put in serial.c, and the base address of the serial ports are defined as macros in machine.h for sharing it between serial.c and early_printk.c

Re: [PATCH -queue 4/7] [loongosn] add a new serial port debug function

In reply to Wu Zhangjin

Quoted 4 lines · Wu Zhangjin

There is an existing serial port debug function: prom_putchar(), but it can only print one char, herein add a new prom_printf(), which works like printk, but print to serial port, which is very important to kernel debugging.

Does this mean early_printk doesn't work for you? We rather get that to work for you than introducing something equivalent.

Re: [PATCH -queue 3/7] [loongson] early_printk: fix the variable type of uart_base

The uart_base variable here is not a physical address, so, we replace it by unsigned char *.

This patch registers the reserved pages for loongson family machines.

Hmm... After our recent discussion on your hibernation issues I am wondering if this patch is actually still required or useful?

This patch registers the reserved pages for loongson family machines.
Hmm... After our recent discussion on your hibernation issues I am wondering if this patch is actually still required or useful?

It does not help the hibernation issue, but helps to clear the memory layout to the users(cat /proc/iomem), is this a need?

Seems some of the other architectures, including some MIPS variants have registed the reserved space, so, could you please apply it?

Thanks & Regards,
