Hello,
what has isa_memcpy_fromio() changed to in kernel 2.6.17 from 2.6.16
It was always meant as a transition interface (although it survived
incredibly long). All code that uses the ioremap is unaffected: ie
foo = ioremap(isa_addr, len);
memcpy_fromio(foo + bar, buf, len2)
Stephen,
There were only 3 drivers in 2.6.16 that used isa_memcpy_fromio().
You can look at how they were changed for 2.6.17.
drivers/net/hp100.c and hp-plus.c
drivers/scsi/g_NCR5380.c

Thanks to everyone who replied - I am using a module from source forge,
on my hp laptop,
called omnibook. It allows me to turn off the back light on my n5430.
Below is the
function that uses isa_memcpy_fromio().
static int __init dmi_iterate(void (*decode)(struct dmi_header *))
{
u8 buf[15];
u32 fp=0xF0000;
#ifdef CONFIG_SIMNOW
/*
* Skip on x86/64 with simnow. Will eventually go away
* If you see this ifdef in 2.6pre mail me !
*/
return -1;
#endif
while( fp < 0xFFFFF)
{
isa_memcpy_fromio(buf, fp, 15);
if(memcmp(buf, "_DMI_", 5)==0 && dmi_checksum(buf))
{
u16 num=buf[13]<<8|buf[12];
u16 len=buf[7]<<8|buf[6];
u32 base=buf[11]<<24|buf[10]<<16|buf[9]<<8|buf[8];
if(dmi_table(base,len,num,decode)==0)
return 0;
}
fp+=16;
}
return -1;
}
Would someone recommend how this should be changed?
Thanks,
Steve
