* Merge branch 'for-4.4/io-poll' of git://git.kernel.dk/linux-blockLinus Torvalds2015-11-1033-90/+286
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pull block IO poll support from Jens Axboe: "Various groups have been doing experimentation around IO polling for (really) fast devices. The code has been reviewed and has been sitting on the side for a few releases, but this is now good enough for coordinated benchmarking and further experimentation. Currently O_DIRECT sync read/write are supported. A framework is in the works that allows scalable stats tracking so we can auto-tune this. And we'll add libaio support as well soon. Fow now, it's an opt-in feature for test purposes" * 'for-4.4/io-poll' of git://git.kernel.dk/linux-block: direct-io: be sure to assign dio->bio_bdev for both paths directio: add block polling support NVMe: add blk polling support block: add block polling support blk-mq: return tag/queue combo in the make_request_fn handlers block: change ->make_request_fn() and users to return a queue cookie

| | | | | | | | | | | | | | | | | | btrfs sets ->submit_io(), and we failed to set the block dev for that path.

| * block: add block polling supportJens Axboe2015-11-075-0/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add basic support for polling for specific IO to complete. This uses the cookie that blk-mq passes back, which enables the block layer to pass this cookie to the driver to spin for a specific request. This will be combined with request latency tracking, so we can make qualified decisions about when to poll and when not to. For now, for benchmark purposes, we add a sysfs file that controls whether polling is enabled or not.

| | | | | | | | | | | | | | | | | | | | | | | | Return a cookie, blk_qc_t, from the blk-mq make request functions, that allows a later caller to uniquely identify a specific IO. The cookie doesn't mean anything to the caller, but the caller can use it to later pass back to the block layer. The block layer can then identify the hardware queue and request from that cookie.

It also uses ITIMER_VIRTUAL for its timer which results in the timer being dependent on it running and the cpu load. This patch fixes this by moving to posix high resolution timers firing off CLOCK_MONOTONIC and relaying the timer correctly to the UML userspace. Fixes: - crashes when hosts suspends/resumes - broken userspace timers - effecive ~40Hz instead of what they should be. Note - this modifies skas behavior by no longer setting an itimer per clone(). Timer events are relayed instead. - kernel network packet scheduling disciplines - tcp behaviour especially under load - various timer related corner cases Finally, overall responsiveness of userspace is better.

However the SMP code added a year and a half later didn't set up the IRQ stack when bringing up secondary CPUs, resulting in a crash when SMP is configured with 4KiB stacks, as soon as the first interrupt arrived on a secondary CPU.

So if the driver is built-in and probed before a firmware is available, this is not loaded and the chip does not work. This happens for example if an initramfs isn't used since the driver is probed before the root filesystem is mounted. Change the default config since the driver isn't needed for machines to boot and is more convenient to have it enabled as a module to avoid requiring an initramfs or to have the firmware built into the kernel.

This option was enabled to have display working on the Exynos5250 Snow Chromebook by commit da9d0fbf5e9a ("ARM: exynos: defconfig update") since proper DRM/KMS support did not exist at that time. But now that the Exynos DRM driver has support for this hardware, there is no need to have simplefb enabled. In fact, if a user has a u-boot that injects the simplefb dev node to the FDT before pass it to the kernel, display won't be properly initialized and only a blank screen will be shown since there isn't a proper handoff from the simplefb driver to the Exynos DRM driver.
