Subject: I2C from interrupt context?
Date: Fri, 07 Nov 2008 00:44:48 +0100	[thread overview]
Message-ID: <m3bpws8ln3.fsf@maximus.localdomain> (raw)

Hi,

I'm updating my EEPROM console logger and have encountered a problem
- the logger (as any console) can be called with hardware interrupts
disabled and/or from interrupt context. It needs to write to I^2C
(using ARM (Xscale) GPIO) and possibly SMBUS-only EEPROM chip. Is it
at all supposed to be possible?
