Owner ID wraparound problem during _BST

Owner ID wraparound problem during _BST

[Manish Prasad]

Hi

I'm using 2.4.20 kernel with ACPI-patch 20021212. I found on sourceforge
that 20030523 has fixed the OwnerId wraparound problem. I'm currently
looking at the new sources and if I'm getting it right, the only change
related to this is in aclocal.h, where the values of ACPI_FIRST_METHOD_ID
and ACPI_FIRST_TABLE_ID have been changed to provide more room for
TYPE_METHOD owner_ids to grow before wrapping around (upto 0xF000 as
opposed to 0x8000 earlier). Would be great if some one could confirm if
this is indeed the only change related to fixing this problem. Also, what
exactly is the reason why this value *has* to be 16-bit and not bigger.

Thanks in advance !

Best,
--Manish

Battery status update resolution

[Manish Prasad]

Hi

I apologize upfront, if this is not totally relevant to this list.
Some questions about the update resolution of the battery remaining
capacity status:

What is the capacity status update resolution of a state-of-the-art
'smart' battery ? I'm currently using a Dell Inspiron 2600 with a Sanyo
LION control method battery, which updates its capacity status only for a
change of 30 - 40 mAh in the capacity (as observed through _BST control
method). What exactly is this limitation due to, is it the AML implementation
of the _BST method by the OEM or is it the battery hardware itself (say
number of bits in the A/D converter of the smart battery) ?

Any insights would be greatly appreciated.

Thanks,
--Manish
