I made it switchable with a module parameter, with default "enable" - in case somebody gets problems with it. Unfortunately, I was not able to check if this alone lets you use any bigger blocks with a tape, as my tape seems to only support 1 block size - only "mt setblk 1" is successful, any other value fails. OTOH, testing on a P-133 showed that enabling clustering alone improves throughput by 10% and reduces CPU load by another 10%, so, seems a worthy thing to do. As for setting max_sectors, that might become a separate patch... Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> | 03 October 2006, 14:16:48 UTC |

Some of these prevent oopses when the SG_SCATTER_SZ or scatter_elem_sz are set to inappropriate values. The scatter_elem_sz has been tested up to 4 MB which should make the largest data transfer with one SCSI command, 32 MB less one block, achievable with a relatively small number of elements in the scatter gather list. ChangeLog: - add scatter_elem_sz boot time parameter and sysfs module parameter that is initialized to SG_SCATTER_SZ - the driver will then adjust scatter_elem_sz to be the max(given(scatter_elem_sz), PAGE_SIZE) It will also round it up, if necessary, to be a power of two - clean up sg.h header, correct bad urls and some statements that are no longer valid - make the def_reserved_size sysfs module attribute writable Signed-off-by: Douglas Gilbert <dougg@torque.net> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> | 26 September 2006, 16:23:15 UTC |

| 70e0eb8 | Jeff Dike | 26 September 2006, 06:33:09 UTC | [PATCH] Split i386 and x86_64 ptrace.h The use of SEGMENT_RPL_MASK in the i386 ptrace.h introduced by x86-allow-a-kernel-to-not-be-in-ring-0.patch broke the UML build, as UML includes the underlying architecture's ptrace.h, but has no easy access to the x86 segment definitions. Rather than kludging around this, as in the past, this patch splits the userspace-usable parts, which are the bits that UML needs, of ptrace.h into ptrace-abi.h, which is included back into ptrace.h. Thus, there is no net effect on i386. As a side-effect, this creates a ptrace header which is close to being usable in /usr/include. x86_64 is also treated in this way for consistency. There was some trailing whitespace there, which is cleaned up.

| 75e29b1 | Jeff Dike | 26 September 2006, 06:33:08 UTC | [PATCH] uml: stack usage reduction The KSTK_* macros used an inordinate amount of stack. In order to overcome an impedance mismatch between their interface, which just returns a single register value, and the interface of get_thread_regs, which took a full pt_regs, the implementation created an on-stack pt_regs, filled it in, and returned one field. do_task_stat calls KSTK_* twice, resulting in two local pt_regs, blowing out the stack. This patch changes the interface (and name) of get_thread_regs to just return a single register from a jmp_buf. The include of archsetjmp.h" in registers.h to get the definition of jmp_buf exposed a bogus include of <setjmp.h> in start_up.c. <setjmp.h> shouldn't be used anywhere any more since UML uses the klibc setjmp/longjmp.

| 4b84c69 | Jeff Dike | 26 September 2006, 06:33:04 UTC | [PATCH] uml: Move signal handlers to arch code Have most signals go through an arch-provided handler which recovers the sigcontext and then calls a generic handler. This replaces the ARCH_GET_SIGCONTEXT macro, which was somewhat fragile. On x86_64, recovering %rdx (which holds the sigcontext pointer) must be the first thing that happens. sig_handler duly invokes that first, but there is no guarantee that I can see that instructions won't be reordered such that %rdx is used before that. Having the arch provide the handler seems much more robust. Some signals in some parts of UML require their own handlers - these places don't call set_handler any more. They call sigaction or signal themselves.

This is changed so that only activate_fd calls maybe_sigio_broken, when the descriptor is first seen. reactivate_fd now calls add_sigio_fd, which is symmetric with ignore_sigio_fd. This removes a recursion which makes a critical section look more critical than it really was, obsoleting a big comment to that effect. This requires keeping track of all descriptors which are getting the SIGIO treatment, not just the ones being polled at any given moment, so that reactivate_fd, through add_sigio_fd, doesn't try to tell the SIGIO thread about descriptors it doesn't care about.

Wysocki | 26 September 2006, 06:32:55 UTC | [PATCH] swsusp: Use memory bitmaps during resume Make swsusp use memory bitmaps to store its internal information during the resume phase of the suspend-resume cycle. If the pfns of saveable pages are saved during the suspend phase instead of the kernel virtual addresses of these pages, we can use them during the resume phase directly to set the corresponding bits in a memory bitmap. Then, this bitmap is used to mark the page frames corresponding to the pages that were saveable before the suspend (aka "unsafe" page frames). Next, we allocate as many page frames as needed to store the entire suspend image and make sure that there will be some extra free "safe" page frames for the list of PBEs constructed later. Subsequently, the image is loaded and, if possible, the data loaded from it are written into their "original" page frames (ie. the ones they had occupied before the suspend). The image data that cannot be written into their "original" page frames are loaded into "safe" page frames and their "original" kernel virtual addresses, as well as the addresses of the "safe" pages containing their copies, are stored in a list of PBEs. Finally, the list of PBEs is used to copy the remaining image data into their "original" page frames (this is done atomically, by the architecture-dependent parts of swsusp). Signed-off-by: Rafael J.

| b788db7 | Rafael J. Wysocki | 26 September 2006, 06:32:54 UTC | [PATCH] swsusp: Introduce memory bitmaps Introduce the memory bitmap data structure and make swsusp use in the suspend phase. The current swsusp's internal data structure is not very efficient from the memory usage point of view, so it seems reasonable to replace it with a data structure that will require less memory, such as a pair of bitmaps. The idea is to use bitmaps that may be allocated as sets of individual pages, so that we can avoid making allocations of order greater than 0. For this reason the memory bitmap structure consists of several linked lists of objects that contain pointers to memory pages with the actual bitmap data. Still, for a typical system all of these lists fit in a single page, so it's reasonable to introduce an additional mechanism allowing us to allocate all of them efficiently without sacrificing the generality of the design. This is done with the help of the chain_allocator structure and associated functions. We need to use two memory bitmaps during the suspend phase of the suspend-resume cycle. One of them is necessary for marking the saveable pages, and the second is used to mark the pages in which to store the copies of them (aka image pages). First, the bitmaps are created and we allocate as many image pages as needed (the corresponding bits in the second bitmap are set as soon as the pages are allocated). Second, the bits corresponding to the saveable pages are set in the first bitmap and the saveable pages are copied to the image pages. Finally, the first bitmap is used to save the kernel virtual addresses of the saveable pages and the second one is used to save the contents of the image pages. Signed-off-by: Rafael J.

Add lock annotations to these two functions so that sparse can check callers for lock pairing, and so that sparse will not complain about these functions since they intentionally use locks in this manner.

| 0f0f1b4 | Alan Cox | 26 September 2006, 06:32:34 UTC | [PATCH] Voyager: tty locking Voyager fiddles with current->signal.tty without locking. It turns out that the code in question has already cleared current->signal.tty correctly because daemonize() does the right thing already. The signal handling also appears to be incorrect as it does an unprotected sigfillset that also appears unneccessary.

| 753b9f8 | Dave Hansen | 26 September 2006, 06:32:29 UTC | [PATCH] x86: enable VMSPLIT for highmem kernels The current VMSPLIT Kconfig option is disabled whenever highmem is on. This is a bit screwy because the people who need to change VMSPLIT the most tend to be the ones with highmem and constrained lowmem. So, remove the highmem dependency. But, re-include the dependency for the "full 1GB of lowmem" option. You can't have the full 1GB of lowmem and highmem because of the need for the vmalloc(), kmap(), etc... areas. I thought there would be at least a bit of tweaking to do to get it to work, but everything seems OK.

| 5091e74 | Ian Campbell | 26 September 2006, 06:32:28 UTC | [PATCH] Translate asm version of ELFNOTE macro into preprocessor macro I've come across some problems with the assembly version of the ELFNOTE macro currently in -mm. (in x86-put-note-sections-into-a-pt_note-segment-in-vmlinux.patch) The first is that older gas does not support :varargs in .macro definitions (in my testing 2.17 does while 2.15 does not, I don't know when it became supported). The Changes file says binutils >= 2.12 so I think we need to avoid using it. There are no other uses in mainline or -mm. Old gas appears to just ignore it so you get "too many arguments" type errors. Secondly it seems that passing strings as arguments to assembler macros is broken without varargs. It looks like they get unquoted or each character is treated as a separate argument or something and this causes all manner of grief. I think this is because of the use of -traditional when compiling assembly files. Therefore I have translated the assembler macro into a pre-processor macro. I added the desctype as a separate argument instead of including it with the descdata as the previous version did since -traditional means the ELFNOTE definition after the #else needs to have the same number of arguments (I think so anyway, the -traditional CPP semantics are pretty fscking strange!). With this patch I am able to define elfnotes in assembly like this with both old and new assemblers. ELFNOTE(Xen, XEN_ELFNOTE_GUEST_OS, .asciz, "linux") ELFNOTE(Xen, XEN_ELFNOTE_GUEST_VERSION, .asciz, "2.6") ELFNOTE(Xen, XEN_ELFNOTE_XEN_VERSION, .asciz, "xen-3.0") ELFNOTE(Xen, XEN_ELFNOTE_VIRT_BASE, .long, __PAGE_OFFSET) Which seems reasonable enough.

| 9c9b8b3 | Jeremy Fitzhardinge | 26 September 2006, 06:32:26 UTC | [PATCH] x86: put .note.* sections into a PT_NOTE segment in vmlinux This patch will pack any .note.* section into a PT_NOTE segment in the output file. To do this, we tell ld that we need a PT_NOTE segment. This requires us to start explicitly mapping sections to segments, so we also need to explicitly create PT_LOAD segments for text and data, and map the sections to them appropriately. Fortunately, each section will default to its previous section's segment, so it doesn't take many changes to vmlinux.lds.S. This only changes i386 for now, but I presume the corresponding changes for other architectures will be as simple. This change also adds <linux/elfnote.h>, which defines C and Assembler macros for actually creating ELF notes. Signed-off-by: Jeremy Fitzhardinge <jeremy@xensource.com> Cc: Eric W.
