It was committed to a TI internal tree 29 June/15 July, and sent to the list within a week of the second revision. The people who discovered this are on customer support - we spend a significant amount of time solving bugs like these, but have very little gap before the next big one strikes. We work tight production schedules, getting products out and only just have enough time to inform internal teams, but not enough to check if these fixes apply to internal trees (mainline is far far away) and get them there. (FWIW, Jon's been responsible for discovering and fixing more bugs on OMAP than almost anyone else I know.) For this specific patch, I'm not sure if other TI PM teams even knew about the existence of this patch until end-June. > About two months of it is my fault, since it was posted to l-o on July 21. > But all the time between 12 March and 21 July is up to TI to answer. > This really could have been a useful patch for certain vendors to have > that are using CORE DVFS on their currently-shipping OMAP3 devices. Sure, and I'm certain those other vendors have an equal number of critical bug fixes sitting in their own trees, which they steadfastly refuse to share with other competing vendors until their own products are out. (I have specific examples in mind, but don't want to start another flame war). Grow up - when a bug is discovered in the field, people are not likely to share with others in the interest of their own product timelines. While this may overall be less beneficial for everyone, that is indeed how many think and work. > >> This same bug has been patched in three different trees?

OMAP4 has been demonstrably different - almost every single patch reaches mainline almost as soon as it is discovered. We had new silicon woken up with near-mainline code, and new boards supported in mainline even before the number of boards were in the mid-double digits. We're working very hard to keep things this way - give us a break. Stop inciting flame wars. A little support and understanding on your part would go a long way. - Anand -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
