I've been trying to compile this patch into the 2.6.37rc2 mainline
kernel but have run into a few issues. The reason for trying to get it
up and running with .37 to resolve the well documented lag/speed issues
on Maverick with the .35 kernel.
So I patched the .37 toshiba.acpi with the link above and tried to
compile:
dsm...@pez:/usr/src/linux-2.6.37-rc2/drivers/platform/x86$ sudo make -C
/usr/src/linux-headers-`uname -r` M=`pwd` modules
make: Entering directory `/usr/src/linux-headers-2.6.37-020637rc2-generic'
CC [M] /usr/src/linux-2.6.37-rc2/drivers/platform/x86/toshiba_acpi.o
/usr/src/linux-2.6.37-rc2/drivers/platform/x86/toshiba_acpi.c:819: error:

/usr/src/linux-2.6.37-rc2/drivers/platform/x86/toshiba_acpi.c:820: warning:

Seems that ioctl variable has been removed from 2.6.37rc1. Ioctl was
removed by the merging of the BKL (big kernel lock) tree.
So I hacked toshiba_acpi.c a little to get it compiling from:
(line 859)
static int
tosh_ioctl(struct inode* ip, struct file* fp, unsigned int cmd,
unsigned long arg)
to:
static long
tosh_ioctl(struct file* fp, unsigned int cmd,
unsigned long arg)
and also from:
(line 921)
.ioctl = tosh_ioctl
to:
.compat_ioctl = tosh_ioctl
Compiles clean, inserts and loads up but I cant get access to toshet. What is
interesting is I can cat /proc/toshiba
dsm...@pez:/usr/src/linux-2.6.37-rc2/drivers/platform/x86$ cat /proc/toshiba
1.1 0xfcff 0.0 0.45 0x418e 0x00
Well I'm no kernel hacker and am not really sure what Im doing past
here... any ideas?
