I've gotten a first Linux dmesg on SuperH board.


What do you expect? Maybe this one:

Starting from MBR
Jumping to second stage
START
input_len: 0x00 10 ba f6
Uncompressing Linux... 

ran out of input data

 -- System halted
Not that much as you might expect, but it is something.
Above dmesg says that gzipped image provided has size of 0x10baf6 bytes, which is a bit more than a size of a zImage, and it was failed to get all input data. Precise meaning of that error message is hidden in the magic of gzip decompressor lib/inflate.c, which is a next task to solve, likely because of my broken sector reading code (I seriously doubt it is correct) not everything is in the RAM, so validation logic in the compressor fails and above error happens, I will determine that tomorrow, and now I need to run quickly or I will miss the latest bus home.

What is Linux Kernel Summit in real.


As Jens Axboe (besides other things he is a KS committee member) said to me:

The kernel summit is around 70-80 people, core people is probably around 60-70. The kernel summit is not a conference as such, it's a place to sit and talk about various issues. People don't give slide presentation (the exception here being some corporate sponsors or invited corporate people), the intention is to have a 5 minute intro spark a conversation on the selected topic.
So it is a bit different from what I thought, and it looks it is different in a good direction.

My first SuperH patch has been applied.


It fixed most of the warnings/errors I found during custom config, and is pretty trivial. Patch includes spinlock fixes, read/write lock fixes, SMP build fixes and include mess. Well, word 'fixes' likely is not good enough, but it allows to compile the tree.
