staging: delete rtl8187se wireless driver

2014-04-16T18:35:54+00:00

There is a "real" driver for this hardware now in drivers/net/ so remove the staging version as it's not needed anymore. Reported-by: Xose Vazquez Perez Cc: Larry Finger Cc: John W. Linville" Signed-off-by: Greg Kroah-Hartman

staging: r8723au: Turn on build of new driver

2014-04-05T21:53:46+00:00

This commit also creates a TODO file. Signed-off-by: Larry Finger Cc: Jes Sorensen Signed-off-by: Greg Kroah-Hartman

staging: visorutil driver to provide common functionality to other s-Par drivers

2014-03-05T00:52:12+00:00

The visorutil module is a support library required by all other s-Par driver modules. Among its features it abstracts reading, writing, and manipulating a block of memory. Signed-off-by: Ken Cox Cc: Ben Romer Signed-off-by: Greg Kroah-Hartman

staging: sb105x: delete the driver

2014-02-28T22:21:58+00:00

It's been marked BROKEN for over a year, and no one has stepped up to do anything with the code, and no one has complained. So just delete it. If someone wants to fix it up and merge it "properly", they can revert this commit. Cc: Jiri Slaby Cc: Steven Rostedt Signed-off-by: Greg Kroah-Hartman

staging: echo: move to drivers/misc/

2014-02-28T22:08:42+00:00

The code is clean, there are users of it, so it doesn't belong in staging anymore, move it to drivers/misc/. Cc: Steve Underwood Cc: David Rowe Signed-off-by: Greg Kroah-Hartman

staging: sm7xxfb: remove driver

2014-02-28T22:04:28+00:00

It hasn't been worked on in a very long time, and the original author has moved on to a different product as this one is no longer being made. So remove the driver. If someone wants to resurect it, and clean it up and get it merged to the "proper" part of the kernel, this commit can be reverted. Cc: Teddy Wang Signed-off-by: Greg Kroah-Hartman

staging/bluetooth: Add hci_h4p driver

Pull rtl8812ae staging wireless driver from Greg KH: "Here's a single staging driver for a wireless chipset that has shown up in the SteamBox hardware. It is merged separately from the "main" staging pull request to sync up with the wireless api changes that came in from the networking tree. It's self-contained and works for me and others. Larry will be replacing it with a "real" driver for 3.15, but for now this one is needed" * tag 'staging-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: staging: r8821ae: Enable build by reverting BROKEN marking staging: r8821ae: Fix build problems Staging: rtl8812ae: disable due to build errors Staging: rtl8821ae: add TODO file Staging: rtl8821ae: removed unused functions and variables Staging: rtl8821ae: rc.c: fix up function prototypes Staging: rtl8812ae: Add Realtek 8821 PCI WIFI driver

zram: promote zram from staging

2014-01-31T00:56:55+00:00

Zram has lived in staging for a LONG LONG time and have been fixed/improved by many contributors so code is clean and stable now. Of course, there are lots of product using zram in real practice. The major TV companys have used zram as swap since two years ago and recently our production team released android smart phone with zram which is used as swap, too and recently Android Kitkat start to use zram for small memory smart phone. And there was a report Google released their ChromeOS with zram, too and cyanogenmod have been used zram long time ago. And I heard some disto have used zram block device for tmpfs. In addition, I saw many report from many other peoples. For example, Lubuntu start to use it. The benefit of zram is very clear. With my experience, one of the benefit was to remove jitter of video application with backgroud memory pressure. It would be effect of efficient memory usage by compression but more issue is whether swap is there or not in the system. Recent mobile platforms have used JAVA so there are many anonymous pages. But embedded system normally are reluctant to use eMMC or SDCard as swap because there is wear-leveling and latency issues so if we do not use swap, it means we can't reclaim anoymous pages and at last, we could encounter OOM kill. :( Although we have real storage as swap, it was a problem, too. Because it sometime ends up making system very unresponsible caused by slow swap storage performance. Quote from Luigi on Google "Since Chrome OS was mentioned: the main reason why we don't use swap to a disk (rotating or SSD) is because it doesn't degrade gracefully and leads to a bad interactive experience. Generally we prefer to manage RAM at a higher level, by transparently killing and restarting processes. But we noticed that zram is fast enough to be competitive with the latter, and it lets us make more efficient use of the available RAM. " and he announced. http://www.spinics.net/lists/linux-mm/msg57717.html Other uses case is to use zram for block device. Zram is block device so anyone can format the block device and mount on it so some guys on the internet start zram as /var/tmp. http://forums.gentoo.org/viewtopic-t-838198-start-0.html Let's promote zram and enhance/maintain it instead of removing.
