2008-04-22i2c-algo-pca: Extend for future driversWolfram Sang
The separation between algorithm and adapter was unsharp at places. This was partly hidden by the fact, that the ISA-driver allowed just one instance and had all private data in static variables. This patch makes neccessary preparations to add a platform driver on top of the algorithm, while still supporting ISA. Note: Due to lack of hardware, the ISA-driver could not be tested except that it builds. Concerning the core struct i2c_algo_pca_data: - A private data field was added, all hardware dependant data may go here. Similar to other algorithms, now a pointer to this data is passed to the adapter's functions. In order to make as less changes as possible to the ISA-driver, it leaves the private data empty and still only uses its static variables. - A "reset_chip" function pointer was added; such a functionality must come from the adapter, not the algorithm. - use a variable "i2c_clock" instead of a function pointer "get_clock", allowing for write access to a default in case a wrong value was supplied. In the algorithm-file: - move "i2c-pca-algo.h" into "linux/i2c-algo-pca.h" - now using per_instance timeout values (i2c_adap->timeout) - error messages specify the device, not only the driver name - restructure initialization to easily support "i2c_add_numbered_adapter" - drop "retries" and "own" (i2c address) as they were unused (The state-machine for I2C-communication was not touched.) In the ISA-driver: - adapt to new algorithm Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Jean Delvare <khali@linux-fr.org>

2008-04-22[IA64] disable interrupts on exit of ia64_trace_syscallHidetoshi Seto
While testing with CONFIG_VIRT_CPU_ACCOUNTING=y, I found that I occasionally get very huge system time in some threads. So I dug the issue and finally noticed that it was caused because of an interrupt which interrupt in the following window: > [arch/ia64/kernel/entry.S: (!CONFIG_PREEMPT && CONFIG_VIRT_CPU_ACCOUNTING)] > > ENTRY(ia64_leave_syscall) > : > (pUStk) rsm psr.i > cmp.eq pLvSys,p0=r0,r0 // pLvSys=1: leave from syscall > (pUStk) cmp.eq.unc p6,p0=r0,r0 // p6 <- pUStk > .work_processed_syscall: > adds r2=PT(LOADRS)+16,r12 > (pUStk) mov.m r22=ar.itc // fetch time at leave > adds r18=TI_FLAGS+IA64_TASK_SIZE,r13 > ;; > <<< window: from here >>> > (p6) ld4 r31=[r18] // load current_thread_info()->flags > ld8 r19=[r2],PT(B6)-PT(LOADRS) > adds r3=PT(AR_BSPSTORE)+16,r12 > ;; > mov r16=ar.bsp > ld8 r18=[r2],PT(R9)-PT(B6) > (p6) and r15=TIF_WORK_MASK,r31 // any work other than TIF_SYSCALL_TRACE? > ;; > ld8 r23=[r3],PT(R11)-PT(AR_BSPSTORE) > (p6) cmp4.ne.unc p6,p0=r15, r0 // any special work pending? > (p6) br.cond.spnt .work_pending_syscall > ;; > ld8 r9=[r2],PT(CR_IPSR)-PT(R9) > ld8 r11=[r3],PT(CR_IIP)-PT(R11) > (pNonSys) break 0 // bug check: we shouldn't be here if pNonSys is TRUE! > ;; > invala > <<< window: to here >>> > rsm psr.i | psr.ic // turn off interrupts and interruption collection If pUStk is true, it means we are going to return user mode, hence we fetch ar.itc to get time at leave from system. It seems that it is not possible to interrupt the window if pUStk is true, because interrupts are disabled early. And also disabling interrupt makes sense because it is safe for referring current_thread_info()->flags. However interrupting the window while pUStk is true was possible. The route was: ia64_trace_syscall -> .work_pending_syscall_end -> .work_processed_syscall Only in case entering the window from this route, interrupts are enabled during in the window even if pUStk is true. I suppose interrupts must be disabled here anyway if pUStk is true. I'm not sure but afraid that what kind of bad effect were there, other than crazy system time which I found. FYI, there was a commit 6f6d75825dc49b082906b84537b4df28293c2977 that points out a bug at same point(exit of ia64_trace_syscall) in 2006. It can be said that there was an another bug.

2008-04-22HID: Suppress hidinput for Samsung IR controlRobert Schedel
Samsung USB remotes (0419:0001) report six keys via standard HID usage pages (arrow keys, OK, Power). Kernel 2.6.25 maps those to input events (in addition to the hiddev report). The remaining 43 keys are reported via proprietary HID report page and therefore by hiddev only. Applications using hiddev and input device might process the 6 standard keys twice. To avoid this, the input device will be suppressed for the Samsung remote with a quirk entry, forcing to use the hiddev device only. LIRC already contains the proper support.

2008-04-22HID: quirk for MS Wireless Desktop Receiver (model 1028)Jim Duchek
Microsoft's wireless desktop receiver (Model 1028) has a bug in the report descriptor -- namely, in four seperate places it uses USAGE_MIN and _MAX when it quite obviously doesn't intend to. In other words, it reports that it has pretty much _everything_ in 'consumer' and 'generic desktop'. And then the X evdev driver believes I have a mouse with 36 absolute axes and a huge pile of keys and buttons, when I in fact, should have zero. 255/256 in three of the cases, and 0-1024 in another.

2008-04-22HID: fixup fullspeed interval on highspeed Afatech DVB-T IR kbdPekka Sarnila
Many vendors highspeed devices give erroneously fullspeed interval value in endpoint descriptor for interrupt endpoints. This quirk fixes up that by recalculating the right value for highspeed device. At the time of hid configuration this quirk calculates which highspeed interval value gives same interval delay as, or next smaller then, what it would be if the original value would be interpreted as fullspeed value. In subsequent urbs that new value is used instead. Forming the 'hid->name' in usb_hid_config() was moved up to accommodate more descriptive printk reporting the fixup. In this patch the quirk is set for one such device: Afatech DVB-T 2 infrared HID-keyboard. It reports value 16 which means 4,069s in highspeed while obviously 16ms was intended. In this case quirk calculates new value to be 8 which gives when interpreted as highspeed value 16ms as wanted. The behavior of the device was verified to be what expected both before and after the patch. Signed-off-by: Pekka Sarnila <sarnila@adit.fi> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
