Hi!
I been working on updating the VIA kernel driver to using KMS and TTM. So this weekend I started to implement a couple of buffer allocations internally to the driver from the video ram. So the first buffer I allocated was not the front buffer from the video vram but a virtual queue buffer of about 256K in size. The second allocation was the front buffer. The problem was the buffer offset for the second allocation was the same as the VQ buffer. I'm stump to what I'm doing wrong, so does anyone have a idea?
Without code to look at we all can start guessing :) my guess is either you are not using the proper offset field or you are allocating from different memory pool.
Second question I have is how are monochrome cursor images handled with KMS. Yes we need to support CLE266 which is used in a lot of POS devices. That chipset only supports monochrome cursors.
You can hide the cursor limitation from userspace and pretend supporting rgb cursor.
