Chronicler Zack Brown reports on the latest news, views, dilemmas, and developments within the Linux kernel community. He and Pali went back and forth a little on technical considerations, but there was no ultimate design resolution. Using two transfers was kind of racy and caused wrong results to be returned sometimes. IMO we don’t need to shutdown on battery cold we just may not charge the batterybut we need to shutdown on battery dead.

Article This patch series contains a few updates for the bq27x00 driver: Traffic volumes are immense, often reaching 10, messages in a week, and keeping up to date with the entire scope of development is a virtually impossible task for one person.

Maybe kernel should issue emergency shutdown e. He posted a patch to do this. Poll battery state bq27x He proposed making the exact voltage configurable, and he added, “Also, the shutdown voltage can depend on external devices connected.

Later, Pavel had second thoughts about whether or not to let this whole feature be configurable at all. KVM brings the kernel into the virualization game.

Reinvent your network with DevOps tools and techniques: One of the few brave souls to take on this task is Zack Brown. He said, “we probably need to create battery object in the device tree, then add properties there.

The other patch fixes the i2c read function to use a single i2c transfer to read a register instead of two transfers.

On the other hand it allows the property to be queried at a limux rate then the caching time. It looks like we should respect hardware telling us battery is dead, and only use low hardcoded voltages as a fallback.

Tue, 22 Feb Add new properties linuz It could be for example 3. Pavel groaned, in a friendly way, and agreed that, yes, making it configurable would probably be the way to go.
