* | Input: i8042 - i8042_flush fix for a full 8042 bufferAndrey Moiseev2013-09-181-9/+14
|/ | | | | | | | | | | | | | | | | When 8042 internal data buffer is full, the driver erroneously decides that the controller is not present. i8042_flush returns the number of flushed bytes, which is in 0 - I8042_BUFFER_SIZE range inclusive. Therefore, i8042_flush has no way to indicate an error. Moreover i8042_controller_check takes initially full buffer (i8042_flush returned I8042_BUFFER_SIZE) as a sign of absence of the controller. Let's change i8042 to return success/error instead and make sure we do not return error prematurely.

| | | | | | | | | | | | | | | In addition to some laptops needing i8042 reset after resuming from S2R to get their touchpads working there is another class of laptops - ones that need i8042 reset before going to S2R, otherwise they will simply reboot instead of resuming. See https://bugzilla.kernel.org/show_bug.cgi?id=15612 This change forces reset of i8042 before doing S2R.

* Input: i8042 - downgrade selftest error message to dbg()Paul Bolle2011-03-311-3/+4
| | | | | | | | | | | | | | | | | On a "really fragile" laptop I noticed a single i8042.c: i8042 controller selftest failed. (0x1 != 0x55) error in the log. But there's no reason to print this message at KERN_ERR level each time that loop fails, especially since the message telling about the overall selftest failure is printed at KERN_INFO level (on X86). Add an actual error message for non-X86 systems, where a selftest failure is (apparently) more serious. Remove a space in an another error message.

* panic: keep blinking in spite of long spin timer modeTAMUKI Shoichi2010-08-111-20/+5
| | | | | | | | | | | | | | | | | | | | | To keep panic_timeout accuracy when running under a hypervisor, the current implementation only spins on long time (1 second) calls to mdelay. That brings a good effect, but the problem is the keyboard LEDs don't blink at all on that situation. This patch changes to call to panic_blink_enter() between every mdelay and keeps blinking in spite of long spin timer mode. The time to call to mdelay is now 100ms. Even this change will keep panic_timeout accuracy enough when running under a hypervisor.

* | include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

| | | | | | | | | | | | | | | | | The serio ports on i8042 are not completely isolated; while we provide enough locking to ensure proper serialization when accessing control and data registers AUX and KBD ports can still have an effect on each other on PS/2 protocol level. The most prominent effect is that issuing a command for the device connected to one port may cause abort of the command currently executing by the device connected to another port. Since i8042 nor serio subsystem are not aware of the details of the PS/2 protocol (length of the commands and their replies and so on) the locking should be done on libps2 level by adding special handling when we see that we are dealing with serio port on i8042.

| | | | | | | | | | | | | | | | | | It seems that many laptops do not fully implement AUX LOOP command in their keyboard controllers, causing issues with touchpad detection. We know however that almost every laptop/portable uses a PS/2 pointing device and, even if user disables it in favor of an external mouse, the system will not use IRQ 12 for anything else. Therefore we may bypass AUX IRQ delivery test when running on a laptop and assume that it is routed properly. Just to be safe we require the box to have good PNP data in order to bypass the test.

* | Input: i8042 - restore control register when enabling port failsMarkus Armbruster2007-07-181-0/+4
|/ | | | | | | | | | When enabling interrupts for a port fails, the interrupt enable and port enable bits remain set in i8042_ctr. Later writes of i8042_ctr to the hardware could accidentally retry enabling interrupts. Clear the bits on failure.

* Input: i8042 - fix AUX port detection with some chipsRoland Scheidegger2007-05-081-6/+29
| | | | | | | | | | | | The i8042 driver fails detection of the AUX port with some chips, because they apparently do not change the I8042_CTR_AUXDIS bit immediately. This is known to affect at least HP500/HP510 notebooks, consequently the built-in touchpad will not work. The patch will simply reread the value until it gets the expected value or a retry limit is hit, without touching other workaround code in the same area.
