* powerpc/mpc5200: Bugfix on handling variable sized buffer descriptorsGrant Likely2008-12-211-19/+42
| | | | | | | | | | | | | | | | | | | | | | | The buffer descriptors for the ATA BestComm task are larger than the current definition for bcom_bd. This causes problems because the various bcom_... functions dereference the buffer descriptor pointer by using the array operator which doesn't work when the buffer descriptors are a different size. This patch adds the bcom_get_bd() function which uses the value in bcom_task.bd_size to calculate the offset into the BD table. This patch also changes the definition of bcom_bd to specify a data size of 0 instead of 1 so that it will never work if anyone attempts to dereference the bd list as an array (as opposed to something that might work even though it is wrong). Finally, this patch moves the definition of bcom_bd up in the file to eliminate a forward declaration. Based on patch originally written by Tim Yamin.

* powerpc/mpc5200: Make internal 5200 PIC the default interrupt controllerGrant Likely2008-12-211-0/+2
| | | | | | | | | | The MPC5200 internal interrupt controller setup function needs to set the default interrupt controller when it is called.

| | | | | | | | | | | | This patch adds documentation to the mpc5200 interrupt controller driver and cleans up some minor coding conventions. It also moves the contents of mpc52xx_pic.h into the driver proper (except for a small common bit that is moved to the common mpc52xx.h) because the information encoded there is not required by any other part of kernel code. Finally for code readability sake, the L2_OFFSET shift value is removed because the code using it resolves to a noop. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

* powerpc/44x: 44x TLB doesn't need "Guarded" set for all pagesBenjamin Herrenschmidt2008-12-211-1/+11
| | | | | | | | | | | | | | | | | | | | After discussing with chip designers, it appears that it's not necessary to set G everywhere on 440 cores. The various core errata related to prefetch should be sorted out by firmware by disabling icache prefetching in CCR0. We add the workaround to the kernel however just in case oooold firmwares don't do it. This is valid for -all- 4xx core variants. Later ones hard wire the absence of prefetch but it doesn't harm to clear the bits in CCR0 (they should already be cleared anyway). We still leave G=1 on the linear mapping for now, we need to stop over-mapping RAM to be able to remove it.

* powerpc/mm: Rework usage of _PAGE_COHERENT/NO_CACHE/GUARDEDBenjamin Herrenschmidt2008-12-219-77/+68Star
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we never set _PAGE_COHERENT in the PTEs, we just OR it in in the hash code based on some CPU feature bit. We also manipulate _PAGE_NO_CACHE and _PAGE_GUARDED by hand in all sorts of places. This changes the logic so that instead, the PTE now contains _PAGE_COHERENT for all normal RAM pages thay have I = 0 on platforms that need it. The hash code clears it if the feature bit is not set. It also adds some clean accessors to setup various valid combinations of access flags and change various bits of code to use them instead. This should help having the PTE actually containing the bit combinations that we really want. I also removed _PAGE_GUARDED from _PAGE_BASE on 44x and instead set it explicitely from the TLB miss. I will ultimately remove it completely as it appears that it might not be needed after all but in the meantime, having it in the TLB miss makes things a lot easier.

* powerpc/mm: Runtime allocation of mmu context maps for nohash CPUsBenjamin Herrenschmidt2008-12-213-54/+116
| | | | | | | | | | | | | | | | | | This makes the MMU context code used for CPUs with no hash table (except 603) dynamically allocate the various maps used to track the state of contexts. Only the main free map and CPU 0 stale map are allocated at boot time. Other CPU maps are allocated when those CPUs are brought up and freed if they are unplugged. This also moves the initialization of the MMU context management slightly later during the boot process, which should be fine as it's really only needed when userland if first started anyways.

* powerpc/mm: Split low level tlb invalidate for nohash processorsBenjamin Herrenschmidt2008-12-217-249/+292
| | | | | | | | | | | | | | | | | | | | | | | Currently, the various forms of low level TLB invalidations are all implemented in misc_32.S for 32-bit processors, in a fairly scary mess of #ifdef's and with interesting duplication such as a whole bunch of code for FSL _tlbie and _tlbia which are no longer used. This moves things around such that _tlbie is now defined in hash_low_32.S and is only used by the 32-bit hash code, and all nohash CPUs use the various _tlbil_* forms that are now moved to a new file, tlb_nohash_low.S. I moved all the definitions for that stuff out of include/asm/tlbflush.h as they are really internal mm stuff, into mm/mmu_decl.h The code should have no functional changes. I kept some variants inline for trivial forms on things like 40x and 8xx.

* powerpc/mm: Add SMP support to no-hash TLB handlingBenjamin Herrenschmidt2008-12-2110-57/+281
| | | | | | | | | | | | | | | | This commit moves the whole no-hash TLB handling out of line into a new tlb_nohash.c file, and implements some basic SMP support using IPIs and/or broadcast tlbivax instructions. Note that I'm using local invalidations for D->I cache coherency. At worst, if another processor is trying to execute the same and has the old entry in its TLB, it will just take a fault and re-do the TLB flush locally (it won't re-do the cache flush in any case).

* powerpc/mm: Rework context management for CPUs with no hash tableBenjamin Herrenschmidt2008-12-216-54/+234
| | | | | | | | | | | | | | | | | | | | | | | | This reworks the context management code used by 4xx,8xx and freescale BookE. It adds support for SMP by implementing a concept of stale context map to lazily flush the TLB on processors where a context may have been invalidated. This also contains the ground work for generalizing such lazy TLB flushing by just picking up a new PID and marking the old one stale. This will be implemented later. This is a first implementation that uses a global spinlock. Ideally, we should try to get at least the fast path (context ID already assigned) lockless or limited to a per context lock, but for now this will do. I tried to keep the UP case reasonably simple to avoid adding too much overhead to 8xx which does a lot of context stealing since it effectively has only 16 PIDs available.

* powerpc: Add reboot notifier to Collaborative Memory ManagerBrian King2008-12-211-1/+28
| | | | | | | | | | | | | | When running Active Memory Sharing, pages can get marked as "loaned" with the hypervisor by the CMM driver. This state gets cleared by the system firmware when rebooting the partition. When using kexec to boot a new kernel, this state never gets cleared and the hypervisor and CMM driver can get out of sync with respect to the number of pages currently marked "loaned". Fix this by adding a reboot notifier to the CMM driver to deflate the balloon and mark all pages as active.

* powerpc: Disable Collaborative Memory Manager for kdumpBrian King2008-12-211-1/+1
| | | | | | | | | | | | | | | | | | When running Active Memory Sharing, the Collaborative Memory Manager (CMM) may mark some pages as "loaned" with the hypervisor. Periodically, the CMM will query the hypervisor for a loan request, which is a single signed value. When kexec'ing into a kdump kernel, the CMM driver in the kdump kernel is not aware of the pages the previous kernel had marked as "loaned", so the hypervisor and the CMM driver are out of sync. This results in the CMM driver getting a negative loan request, which can then get treated as a large unsigned value and can cause kdump to hang due to the CMM driver inflating too large. Since there really is no clean way for the CMM driver in the kdump kernel to clean this up, simply disable CMM in the kdump kernel. This fixes hangs we were seeing doing kdump with AMS.

| | | | | | | | | | | | | | | | The ctrl-o (^O) is a common control key used by several applications, such as vim, but hvc_console uses ^O as the magic-sysrq key. This commit allows users to send ^O to applications by pressing ^O twice in succession. To implement this, this commit introduces a check if ^O is pressed again if the sysrq_pressed variable is already set. In this case, clear sysrq_pressed state and flip the ^O character to the tty.

It's feasible that the PowerPC version may wish to use my global one instead. The NOMMU vm_region struct defines areas of the physical memory map that are under mmap. This may include chunks of RAM or regions of memory mapped devices, such as flash. It is also used to retain copies of file content so that shareable private memory mappings of files can be made.

| | * | USB: add 5372:2303 to pl2303Matthew Arnold2008-12-172-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the "Superial" USB-Serial converter to pl2303 so that it is detected, by the correct driver. Adds the relevant vendor:product (5372:2303) to the device tables in pl2303.c & pl2303.h. The patch has been tested against 2.6.24-22-generic.

| | * | USB: skip Set-Interface(0) if already in altsetting 0Alan Stern2008-12-171-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a driver unbinds from an interface, usbcore always sends a Set-Interface request to reinstall altsetting 0. Unforunately, quite a few devices have buggy firmware that crashes when it receives this request. To avoid such problems, this patch (as1180) arranges to send the Set-Interface request only when the interface is not already in altsetting 0.

| | * | USB: fix comment about endianness of descriptorsPhil Endecott2008-12-172-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a comment and clarifies the documentation about the endianness of descriptors. The current policy is that descriptors will be little-endian at the API even on big-endian systems; however the /proc/bus/usb API predates this policy and presents descriptors with some multibyte fields byte-swapped.
