Hi folks As s390 is currently not in a good shape, I tried to produce a list of things which needs to be done for a possible etch release of this architecture. Please provide some feedback. Hardware configuration ====================== In linux 2.6, the complete hardware configuration on s390 is done via sysfs. This needs some program which reads the needed informations from a config and puts them into sysfs. There are two call modes: - via udev, - by an init script. Via udev -------- udev gets events when the channels got available and can call our program which sets up this one channel and the assigned driver. There is one possible problem with that: udev paralizes the events, which makes it impossible to predict the order of the devices. Another problem: we can't enable the devices in config order, only in channel number order. This can be fixed with a mix between both modes. Both problems needs some discussion with udev upstream. By an init script ----------------- The tool will just crawl through all available channels and configure those, which have a config entry or it will crawl through the config entries and configure any available channels. Hardware configuration utility for d-i ====================================== There needs to be some changed in s390-dasd and s390-netdevice to read the informations from sysfs and generate configs usable by the real configuration tools. One problem: We need to make sure that the order of the devices in the installer is the same than in the installed system. s390 support in partman ======================= There is some type of s390/dasd support available for parted, it just completely disables the check for the sector size, as parted hardcodes this in too many places and dasds don't follow this. Maybe this can be fixed in a proper way. partman needs to be fixed to use a correct block size for the devices (1024 byte blocks on a 4096 bytes sectors device just don't work).
