Toshiba Satellite L10-101 Smart Battery System works with patched DSDT

Toshiba Satellite L10-101 Smart Battery System works with patched DSDT

[Thomas Renninger]

Hi,

I just want to add this one to the list of working Smart Battery Systems with 
the DSDT patch from https://sourceforge.net/projects/sbs-linux/.

Are there still efforts for integrating something into the kernel to let those 
systems run out of box?

That would be really interesting. The problem is that the ec-nospinlock
patch in that project just works for kernels 2.6.10/11/12 but not for
the current 2.6.13 kernel. I already tried to adapt it but i need a lot
more knowledge of acpi/kernel hacking to achieve this.

To summarize it: The above patch lets you see your smart battery systems
but depending on what kernel you are using you will lose interrupts
which results in e.g. lost keypresses if the battery is read. If any of
the kernel hackers could drop a note what is planned to solve these
sbs-related issues it would make some people happy. The patch above is
written by Rich Townsend who seem not to continue his project.

have you tried to boot you machine with the kernel parameter ec_burst=1. This 
works on my machine. Up to kernel 2.6.11 I've used Rich Townsends spinlock 
patch. But afterwards i found a posting from Luming Yu in which he asked to 
try his patche which should solve this interrupt issue. And fortunately his 
patches found the way to the kernel-sources :-)
Perhaps you should have a look at /drivers/acpi/ec.c. If there is something 
like setup("ec_burst= ...  you may give this a try.

regards and good luck
	Olaf

Ahh great. This is my log output:

Oct 19 20:39:40 sleipnir Kernel command line: root=/dev/hda7
resume=/dev/hda5 acpi_os_name="Microsoft Windows XP" ec_burst=1 lapic
Oct 19 20:39:40 sleipnir ACPI: EC burst mode.

Can someone tell me what is the aim of the EC burst mode, what does it
do?

Hi,

I am attaching patch (kernel 2.6.14-rc3-git4) with SBS drivers based on
drivers which were written by Rich Townsend and Bruno Ducrot.

At least these updated drivers work on Acer TravelMate 2300.

Vladimir.
