Hello all, I am looking for a way, preferably with the acpi/ec driver, to execute multiple EC transactions atomically (with respect to other transactions). Unfortunately, I have failed to find any promising functions in that driver. Please let me know if I have missed anything. The reason I would like to do it is that I have a computer in which the EC appears to have paged memory, and a series of commands must be executed to read/write data in arbitrary pages, and I would like to guarantee that they are executed as one atomic block. If there is no facility that would allow it to be done, then am I right in assuming that making drivers/acpi/ec.c:acpi_ec_transaction accept multiple transactions, that it then executes sequentially while holding the mutex, should achieve the goal without much difficulty? I think that could work, however, I am not really familiar with ACPI or the EC driver. I would greatly appreciate any help, feedback. Thank your for your time. Barnabás Pőcze
