Hi, I posted these patches a few weeks ago. Is it possible to get a feedback for this submission? Thank you for your help. -- Jeremie Samuel Parrot S.A. Software Engineer 14, quai de Jemmapes R&D/OS Platform 75010 Paris, France http://www.parrot.com On 24/05/2013 18:00, Jérémie Samuel wrote:
Hi all, Currently the sdhci driver does everything in the atomic context. And what is worse, PIO transfers are made from the IRQ handler. Some patches were already submitted to solve this issue. But there were rejected because they involved new issues. This set of patches is an evolution of an old patch from Anton Vorontsov. I tried to fix all the problems involved by the patches. I tested it for several time now with SD cards and SDIO. So, this patch set reworks sdhci code to avoid atomic context, almost completely. Thanks, Jeremie Samuel Jeremie Samuel (8): sdhci: Turn timeout timer into delayed work sdhci: Turn tuning timeout timer into delayed work sdhci: Use work structs instead of tasklets sdhci: Use threaded IRQ handler sdhci: Delay led blinking sdhci: Turn host->lock into a mutex sdhci: Get rid of mdelay()s where it is safe and makes sense sdhci: Use jiffies instead of a timeout counter drivers/mmc/host/sdhci.c | 327 ++++++++++++++++++++++----------------------- include/linux/mmc/sdhci.h | 13 +- 2 files changed, 168 insertions(+), 172 deletions(-)
