* [PATCH] x86: convert bigsmp to use flat physical modeAshok Raj2006-01-062-45/+38
| | | | | | | | | | | | | | | | | | | | | | | | When we bring up a new CPU via INIT/startup IPI messages, the CPU that's coming up sends a xTPR message to the chipset. Intel chipsets (at least) don't provide any architectural guarantee on what the chipset will do with this message. For example, the E850x chipsets uses this xTPR message to interpret the interrupt operating mode of the platform. When the CPU coming online sends this message, it always indicates that it is in logical flat mode. For the CPU hotplug case, the platform may already be functioning in cluster APIC mode at this time, the chipset can get confused and mishandle I/O device and IPI interrupt routing. The situation eventually gets corrected when the new CPU sends another xTPR update when we switch it to cluster mode, but there's a window during which the chipset may be in an inconsistent state. This patch avoids this problem by using the flat physical interrupt delivery mode instead of cluster mode for bigsmp (>8 cpu) support.

* [PATCH] i386 sparsemem for single node systemsAndy Whitcroft2006-01-062-2/+14
| | | | | | | | | | | | | | Allow SPARSEMEM to be enabled on non-numa x86 systems. This is made dependant on EXPERIMENTAL also being set. When an in-tree user (such as simulated numa) exists it should be made dependant on that. The plan is to have no options and no selector as normal when !EXPERIMENTAL. When EXPERIMENTAL we enable the FLATMEM and SPARSEMEM options for X86_PC whilst maintaining DISCONTIGMEM and SPARSEMEM for NUMA.

| | | | | | | | | | | | | | | | | Bug fix required for the .rodata work on x86-64: when change_page_attr() and friends need to break up a 2Mb page into 4Kb pages, it always set the NX bit on the PMD, which causes the cpu to consider the entire 2Mb region to be NX regardless of the actual PTE perms. This is fine in general, with one big exception: the 2Mb page that covers the last part of the kernel .text! The fix is to not invent a new permission for the new PMD entry, but to just inherit the existing one minus the PSE bit.

| | | | | | | | | | | | | | | | PnP BIOS data, code, and 32-bit entry segments all have fixed limits as well; set them in the GDT rather than adding more code. It would be nice to add these fixups to the boot GDT rather than setting the GDT for each CPU; perhaps I can wiggle this in later, but getting it in before the subsys init looks tricky. Also, make some progress on deprecating the ugly Q_SET_SEL macros.

* [PATCH] x86: Pnp byte granularityZachary Amsden2006-01-063-8/+11
| | | | | | | | | | | | | | | | | | | | | | | The one remaining caller of set_limit, the PnP BIOS code, calls into the PnP BIOS, passing kernel parameters in and out. These parameteres may be passed from arbitrary kernel virtual memory, so they deserve strict protection to stop a bad BIOS from smashing beyond the object size. Unfortunately, the use of set_limit was badly botching this by setting the limit in terms of pages, when it really should have byte granularity. When doing this, I discovered my BIOS had the buggy code during the "get system device node" call: mov ax, es:[bx] Which is harmless, but has a trivial workaround.

* [PATCH] x86: Always relax segmentsZachary Amsden2006-01-061-38/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | APM BIOSes have many bugs regarding proper representation of the appropriate segment limits for calling the BIOS. By default, APM_RELAX_SEGMENTS is always turned on to support running the APM BIOS on these buggy machines. Keeping 64k limits poses very little danger to the kernel, because the pages where the APM BIOS is located will always be in low physical memory BIOS areas, which should already be marked reserved, and only buggy BIOSes would possibly overstep the segment bounds with writes to data anyway. Since forcing stricter limits breaks many machines and is not default behavior, it seems reasonable to deprecate the older code which may cause APM BIOS to fault. If you really have a badly enough broken APM BIOS that you have to turn off APM_RELAX_SEGMENTS, seems like the best recourse here would be to disable the APM BIOS and / or not compile it into your kernel to begin with, and / or add your system to the known bad list. The reason I want to deprecate this code is there is underlying brokenness with the set_limit macros, and getting rid of many of the call sites rather than rewriting them seems to be the simplest and most correct course of action.

| | | | | | | | | | | | | | | | | | | | | The attached patch makes FRV signal handling work properly: (1) After do_notify_resume() has been called, the work flags must be checked again (there may be another signal to deliver or the process might require rescheduling for instance). (2) After the signal frame is set up on the userspace stack, ptrace() should be given an opportunity to single-step into the signal handler. (3) The error state from setting up a signal frame should be passed back up the call chain. (4) The segfault handler shouldn't be preemptively reset in the arch if we fail to deliver a SEGV signal: force_sig() will take care of that.

| | | | | | | | | | | | | | | | | | | | | The attached patch makes the SYSV IPC shared memory facilities use the new ramfs facilities on a no-MMU kernel. The following changes are made: (1) There are now shmem_mmap() and shmem_get_unmapped_area() functions to allow the IPC SHM facilities to commune with the tiny-shmem and shmem code. (2) ramfs files now need resizing using do_truncate() rather than by modifying the inode size directly (see shmem_file_setup()). This causes ramfs to attempt to bind a block of pages of sufficient size to the inode. (3) CONFIG_SYSVIPC is no longer contingent on CONFIG_MMU.

* [PATCH] NOMMU: Provide shared-writable mmap support on ramfsDavid Howells2006-01-066-22/+378
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch makes ramfs support shared-writable mmaps by: (1) Attempting to perform a contiguous block allocation to the requested size when truncate attempts to increase the file from zero size, such as happens when: fd = shm_open("/file/on/ramfs", ...): ftruncate(fd, size_requested); addr = mmap(NULL, subsize, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_SHARED, fd, offset); (2) Permitting any shared-writable mapping over any contiguous set of extant pages. get_unmapped_area() will return the address into the actual ramfs pages. The mapping may start anywhere and be of any size, but may not go over the end of file. Multiple mappings may overlap in any way. (3) Not permitting a file to be shrunk if it would truncate any shared mappings (private mappings are copied). Thus this patch provides support for POSIX shared memory on NOMMU kernels, with certain limitations such as there being a large enough block of pages available to support the allocation and it only working on directly mappable filesystems.
