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).

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.

Writing to cntl can be used to stop execution on the spu and to restart it, reading from cntl gives the contents of the current status register. The access is always in ascii, as for most other files. This was always meant to be there, but we had a little problem with writing to runctl so it was left out so far.

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.

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.

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.

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. Signed-off-by: NArnd Bergmann <arnd.bergmann@de.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

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.

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.

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.

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.

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.

It turns out msi_ops was simply not enough to abstract the architecture specific details of msi. So I have moved the resposibility of constructing the struct irq_chip to the architectures, and have two architecture specific functions arch_setup_msi_irq, and arch_teardown_msi_irq. For simple architectures those functions can do all of the work. For architectures with platform dependencies they can call into the appropriate platform code. With this msi.c is finally free of assuming you have an apic, and this actually takes less code.

This patch implements two functions ht_create_irq and ht_destroy_irq for use by drivers. Several other functions are implemented as helpers for arch specific irq_chip handlers. The driver for the card I tested this on isn't yet ready to be merged. However this code is and hypertransport irqs are in use in a few other places in the kernel. Not that any of this will get merged before 2.6.19 Because the ipath-ht400 is slightly out of spec this code will need to be generalized to work there. I think all of the powerpc uses are for a plain interrupt controller in a chipset so support for native hypertransport devices is a little less interesting. However I think this is a half way decent model on how to separate arch specific and generic helper code, and I think this is a functional model of how to get the architecture dependencies out of the msi code.
