I think it has more potential but still needs work and definately conistency, especiall in its usage. The first thing I come up with is a low hanging fruit regarding devm_ioremap_resouce(). This function already checks if the passed resource is valid and gives an error message if not. So, we can remove similar checks from the drivers and get rid of a bit of code and a number of inconsistent error strings. This series only removes the unneeded check iff devm_ioremap_resource follows platform_get_resource directly. The previous version tried to shuffle code if needed, too, what lead to an embarrasing bug. It turned out to me that shuffling code for all cases found will make the automated script too complex, so I am unsure if an automated cleanup is the proper tool for this case. Removing the easy stuff seems worthwhile to me, though. Despite various architectures and platform dependencies, I managed to compile test 45 out of 57 modified files locally using heuristics and defconfigs."

However this works fine for update area where really multiple writes aren't the end of the world, however with create primary surface, you can't ever do multiple writes. So this stop internal kernel writes from doing interruptible waits, because otherwise we have no idea if this write is a new one or a continuation of a previous one. virtual hw sucks more than real hw.

But the user is not supposed to know that we are using CPU hotplug internally within suspend/resume (IOW, the kernel should not silently wreck the user-set file permissions across a suspend cycle). Therefore, we need to preserve the file permissions as they are across suspend/resume. The simplest way to achieve that is to just not touch the sysfs files at all - ie., just ignore the CPU hotplug notifications in the suspend/resume path (_FROZEN) in the cpufreq hotplug callback.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Thinkpad e530's BIOS notifies the AC device first and then sleeps for certain amount of time before doing real work in the EC event handler (_Qxx): Method (_Q27, 0, NotSerialized) { Notify (AC, 0x80) Sleep (0x03E8) Store (Zero, PWRS) PNOT () } This causes the AC driver to report an outdated AC state to user space, because it reads the state information from the device while the EC handler is sleeping. Introduce a quirk to cause the AC driver to wait in acpi_ac_notify() before calling acpi_ac_get_state() on systems known to have this problem and add Thinkpad e530 to the list of quirky machines (with a 1s delay which has been verified to be sufficient for that machine).

| | * | | | ACPI / EC: Restart transaction even when the IBF flag setLan Tianyu2013-05-121-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EC driver works abnormally with IBF flag always set. IBF means "The host has written a byte of data to the command or data port, but the embedded controller has not yet read it". If IBF is set in the EC status and not cleared, this will cause all subsequent EC requests to fail with a timeout error. Change the EC driver so that it doesn't refuse to restart a transaction if IBF is set in the status. Also increase the number of transaction restarts to 5, as it turns out that 2 is not sufficient in some cases. This bug happens on several different machines (Asus V1S, Dell Latitude E6530, Samsung R719, Acer Aspire 5930G, Sony Vaio SR19VN and others).
