77dc2db Mark Assad 05 October 2006, 02:25:05 UTC [PATCH] itmtouch: fix inverted flag to indicate touch location correctly, correct white space There is a bug in the current version of the itmtouch USB touchscreen driver. The if statment that checks if pressure is being applied to the touch screen is now missing a ! (not), so events are no longer being reported correctly. The original source code for this line was as follows: #define UCP(x) ((unsigned char*)(x)) #define UCOM(x,y,z) ((UCP((x)->transfer_buffer)[y]) & (z)) ... if (!UCOM(urb, 7, 0x20)) { And was cleaned to: unsigned char *data = urb->transfer_buffer; .... if (data[7] & 0x20) { (note the lack of '!') This has been tested on an LG L1510BF and an LG1510SF touch screen. Signed-off-by: Mark Assad <massad@gmail.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org> 05 October 2006, 02:44:36 UTC

8676727 Arnd Bergmann 04 October 2006, 15:26:21 UTC [POWERPC] spufs: add infrastructure for finding elf objects This adds an 'object-id' file that the spe library can use to store a pointer to its ELF object. This was originally meant for use by oprofile, but is now also used by the GNU debugger, if available. In order for oprofile to find the location in an spu-elf binary where an event counter triggered, we need a way to identify the binary in the first place. Unfortunately, that binary itself can be embedded in a powerpc ELF binary. Since we can assume it is mapped into the effective address space of the running process, have that one write the pointer value into a new spufs file. When a context switch occurs, pass the user value to the profiler so that can look at the mapped file (with some care).

7650f2f Arnd Bergmann 04 October 2006, 15:26:20 UTC [POWERPC] spufs: support new OF device tree format The properties we used traditionally in the device tree are somewhat nonstandard. This adds support for a more conventional format using 'interrupts' and 'reg' properties. The interrupts are specified in three cells (class 0, 1 and 2) and registered at the interrupt-parent. The reg property contains either three or four register areas in the order 'local-store', 'problem', 'priv2', and 'priv1', so the priv1 one can be left out in case of hypervisor driven systems that access these through hcalls.

cdcc89b Arnd Bergmann 04 October 2006, 15:26:17 UTC [POWERPC] spufs: make mailbox functions handle multiple elements Since libspe2 will provide a function that can read/write multiple mailbox elements at once, the kernel should handle that efficiently. read/write on the three mailbox files can now access the spe context multiple times to operate on any number of mailbox data elements. If the spu application keeps writing to its outbound mailbox, the read call will pick up all the data in a single system call. Unfortunately, if the user passes an invalid pointer, we may lose a mailbox element on read, since we can't put it back. This probably impossible to solve, if the user also accesses the mailbox through direct register access.

ac91cb8 Arnd Bergmann 04 October 2006, 15:26:16 UTC [POWERPC] spufs: use correct pg_prot for mapping SPU local store This hopefully fixes a long-standing bug in the spu file system. An spu context comes with local memory that can be either saved in kernel pages or point directly to a physical SPE. When mapping the physical SPE, that mapping needs to be cache-inhibited. For simplicity, we used to map the kernel backing memory that way too, but unfortunately that was not only inefficient, but also incorrect because the same page could then be accessed simultaneously through a cacheable and a cache-inhibited mapping, which is not allowed by the powerpc specification and in our case caused data inconsistency for which we did a really ugly workaround in user space.

6263203 Arnd Bergmann 04 October 2006, 15:26:15 UTC [POWERPC] spufs: Add infrastructure needed for gang scheduling Add the concept of a gang to spufs as a new type of object. So far, this has no impact whatsover on scheduling, but makes it possible to add that later. A new type of object in spufs is now a spu_gang. It is created with the spu_create system call with the flags argument set to SPU_CREATE_GANG (0x2). Inside of a spu_gang, it is then possible to create spu_context objects, which until now was only possible at the root of spufs. There is a new member in struct spu_context pointing to the spu_gang it belongs to, if any. The spu_gang maintains a list of spu_context structures that are its children. This information can then be used in the scheduler in the future. There is still a bug that needs to be resolved in this basic infrastructure regarding the order in which objects are removed. When the spu_gang file descriptor is closed before the spu_context descriptors, we leak the dentry and inode for the gang. Any ideas how to cleanly solve this are appreciated.

9add11d Arnd Bergmann 04 October 2006, 15:26:14 UTC [POWERPC] spufs: implement error event delivery to user space This tries to fix spufs so we have an interface closer to what is specified in the man page for events returned in the third argument of spu_run. Fortunately, libspe has never been using the returned contents of that register, as they were the same as the return code of spu_run (duh!). Unlike the specification that we never implemented correctly, we now require a SPU_CREATE_EVENTS_ENABLED flag passed to spu_create, in order to get the new behavior. When this flag is not passed, spu_run will simply ignore the third argument now.

28347bc HyeonSeung Jang 04 October 2006, 15:26:13 UTC [POWERPC] spufs: fix context switch during page fault For better explanation, I break down the page fault handling into steps: 1) There is a page fault caused by DMA operation initiated by SPU and DMA is suspended. 2) The interrupt handler 'spu_irq_class_1()/__spu_trap_data_map()' is called and it just wakes up the sleeping spe-manager thread. 3) by PPE scheduler, the corresponding bottom half, spu_irq_class_1_bottom() is called in process context and DMA is restarted. There can be a quite large time gap between 2) and 3) and I found the following problem: Between 2) and 3) If the context becomes unbound, 3) is not executed because when the spe-manager thread is awaken, the context is already saved. (This situation can happen, for example, when a high priority spe thread newly started in that time gap) But the actual problem is that the corresponding SPU context does not work even if it is bound again to a SPU. Besides I can see the following warning in mambo simulator when the context becomes unbound(in save_mfc_cmd()), i.e. when unbind() is called for the context after step 2) before 3) : 'WARNING: 61392752237: SPE2: MFC_CMD_QUEUE channel count of 15 is inconsistent with number of available DMA queue entries of 16' After I go through available documents, I found that the problem is because the suspended DMA is not restarted when it is bound again.

a68cf98 Mark Nutter 04 October 2006, 15:26:12 UTC [POWERPC] spufs: scheduler support for NUMA. This patch adds NUMA support to the the spufs scheduler. The new arch/powerpc/platforms/cell/spufs/sched.c is greatly simplified, in an attempt to reduce complexity while adding support for NUMA scheduler domains. SPUs are allocated starting from the calling thread's node, moving to others as supported by current->cpus_allowed. Preemption is gone as it was buggy, but should be re-enabled in another patch when stable. The new arch/powerpc/platforms/cell/spu_base.c maintains idle lists on a per-node basis, and allows caller to specify which node(s) an SPU should be allocated from, while passing -1 tells spu_alloc() that any node is allowed. Since the patch removes the currently implemented preemptive scheduling, it is technically a regression, but practically all users have since migrated to this version, as it is part of the IBM SDK and the yellowdog distribution, so there is not much point holding it back while the new preemptive scheduling patch gets delayed further.

27d5bf2 Benjamin Herrenschmidt 04 October 2006, 15:26:11 UTC [POWERPC] spufs: cell spu problem state mapping updates This patch adds a new "psmap" file to spufs that allows mmap of all of the problem state mapping of SPEs. It is compatible with 64k pages. In addition, it removes mmap ability of individual files when using 64k pages, with the exception of signal1 and signal2 which will both map the entire 64k page holding both registers. It also removes CONFIG_SPUFS_MMAP as there is no point in not building mmap support in spufs. It goes along a separate patch to libspe implementing usage of that new file to access problem state registers. Another patch will follow up to fix races opened up by accessing the 'runcntl' register directly, which is made possible with this patch.

4d5e392 Haavard Skinnemoen 04 October 2006, 14:02:11 UTC [PATCH] atmel_serial: Fix roundoff error in atmel_console_get_options The atmel_console_get_options() function initializes the baud, parity and bits settings from the actual hardware setup, in case it has been initialized by a e.g. boot loader. The baud rate, however, is not necessarily exactly equal to one of the standard baud rates (115200, etc.) This means that the baud rate calculated by this function may be slightly higher or slightly lower than one of the standard baud rates. If the baud rate is slightly lower than the target, this causes problems when uart_set_option() tries to match the detected baud rate against the standard baud rate, as it will always select a baud rate that is lower or equal to the target rate. For example if the detected baud rate is slightly lower than 115200, usart_set_options() will select 57600. This patch fixes the problem by subtracting 1 from the value in BRGR when calculating the baud rate. The detected baud rate will thus always be higher than the nearest standard baud rate, and uart_set_options() will end up doing the right thing. Tested on ATSTK1000 and AT91RM9200-EK boards. Both are broken without this patch.

c194588 Haavard Skinnemoen 04 October 2006, 14:02:10 UTC [PATCH] AVR32: Allow renumbering of serial devices Allow the board to remap actual USART peripheral devices to serial devices by calling at32_map_usart(hw_id, serial_line). This ensures that even though ATSTK1002 uses USART1 as the first serial port, it will still have a ttyS0 device. This also adds a board-specific early setup hook and moves the at32_setup_serial_console() call there from the platform code.

75d3521 Haavard Skinnemoen 04 October 2006, 14:02:08 UTC [PATCH] atmel_serial: Pass fixed register mappings through platform_data In order to initialize the serial console early, the atmel_serial driver had to do a hack where it compared the physical address of the port with an address known to be permanently mapped, and used it as a virtual address. This got around the limitation that ioremap() isn't always available when the console is being initalized. This patch removes that hack and replaces it with a new "regs" field in struct atmel_uart_data that the board-specific code can initialize to a fixed virtual mapping for platform devices where this is possible. It also initializes the DBGU's regs field with the address the driver used to check against. On AVR32, the "regs" field is initialized from the physical base address when this it can be accessed through a permanently 1:1 mapped segment, i.e. the P4 segment. If regs is NULL, the console initialization is delayed until the "real" driver is up and running and ioremap() can be used.

Instead, it adds adds a flag rcu_ctrlblk.signaled, which records the fact that one of CPUs has sent a resched IPI since the last rcu_start_batch(). Roughly speaking, we need two rcu_start_batch()s in order to move callbacks from ->nxtlist to ->donelist. This means that when ->qlen exceeds qhimark and continues to grow, we should send a resched IPI, and then do it again after we gone through a quiescent state. On the other hand, if it was already sent, we don't need to do it again when another CPU detects overflow of the queue. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Acked-by: Paul E.

75cfef3 Josh Triplett 04 October 2006, 09:17:12 UTC [PATCH] rcu: Fix sign bug making rcu_random always return the same sequence rcu_random uses a counter rrs_count to occasionally mix data from get_random_bytes into the state of its pseudorandom generator. However, the rrs_counter gets declared as an unsigned long, and rcu_random checks for --rrs_count < 0, so this code will never mix any real random data into the state, and will thus always return the same sequence of random numbers. Also, change the return value of rcu_random from long to unsigned long, to avoid potential issues caused by the use of the % operator, which can return negative values for negative left operands.

b4dfdbb Alan Stern 04 October 2006, 09:17:06 UTC [PATCH] cpufreq: make the transition_notifier chain use SRCU This patch (as762) changes the cpufreq_transition_notifier_list from a blocking_notifier_head to an srcu_notifier_head. This will prevent errors caused attempting to call down_read() to access the notifier chain at a time when interrupts must remain disabled, during system suspend. It's not clear to me whether this is really necessary; perhaps the chain could be made into an atomic_notifier. However a couple of the callout routines do use blocking operations, so this approach seems safer. The head of the notifier chain needs to be initialized before use; this is done by an __init routine at core_initcall time. If this turns out not to be a good choice, it can easily be changed.

e6a9201 Alan Stern 04 October 2006, 09:17:05 UTC [PATCH] SRCU: report out-of-memory errors Currently the init_srcu_struct() routine has no way to report out-of-memory errors. This patch (as761) makes it return -ENOMEM when the per-cpu data allocation fails. The patch also makes srcu_init_notifier_head() report a BUG if a notifier head can't be initialized. Perhaps it should return -ENOMEM instead, but in the most likely cases where this might occur I don't think any recovery is possible. Notifier chains generally are not created dynamically.

eabc069 Alan Stern 04 October 2006, 09:17:04 UTC [PATCH] Add SRCU-based notifier chains This patch (as751) adds a new type of notifier chain, based on the SRCU (Sleepable Read-Copy Update) primitives recently added to the kernel. An SRCU notifier chain is much like a blocking notifier chain, in that it must be called in process context and its callout routines are allowed to sleep. The difference is that the chain's links are protected by the SRCU mechanism rather than by an rw-semaphore, so calling the chain has extremely low overhead: no memory barriers and no cache-line bouncing. On the other hand, unregistering from the chain is expensive and the chain head requires special runtime initialization (plus cleanup if it is to be deallocated). SRCU notifiers are appropriate for notifiers that will be called very frequently and for which unregistration occurs very seldom. The proposed "task notifier" scheme qualifies, as may some of the network notifiers. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Paul E.

621934e Paul E. McKenney 04 October 2006, 09:17:02 UTC [PATCH] srcu-3: RCU variant permitting read-side blocking Updated patch adding a variant of RCU that permits sleeping in read-side critical sections. SRCU is as follows: o Each use of SRCU creates its own srcu_struct, and each srcu_struct has its own set of grace periods. This is critical, as it prevents one subsystem with a blocking reader from holding up SRCU grace periods for other subsystems. o The SRCU primitives (srcu_read_lock(), srcu_read_unlock(), and synchronize_srcu()) all take a pointer to a srcu_struct. o The SRCU primitives must be called from process context. o srcu_read_lock() returns an int that must be passed to the matching srcu_read_unlock(). Realtime RCU avoids the need for this by storing the state in the task struct, but SRCU needs to allow a given code path to pass through multiple SRCU domains -- storing state in the task struct would therefore require either arbitrary space in the task struct or arbitrary limits on SRCU nesting. So I kicked the state-storage problem up to the caller. Of course, it is not permitted to call synchronize_srcu() while in an SRCU read-side critical section. o There is no call_srcu(). It would not be hard to implement one, but it seems like too easy a way to OOM the system. (Hey, we have enough trouble with call_rcu(), which does -not- permit readers to sleep!!!) So, if you want it, please tell me why... [josht@us.ibm.com: sparse notation] Signed-off-by: Paul E.
