* An addendum to r195649, "Add support to the virtual memory system forAlan Cox2009-07-183-21/+18
| | | | | | | | | | | | | | | | | | | configuring machine-dependent memory attributes...": Don't set the memory attribute for a "real" page that is allocated to a device object in vm_page_alloc(). It is a pointless act, because the device pager replaces this "real" page with a "fake" page and sets the memory attribute on that "fake" page. Eliminate pointless code from pmap_cache_bits() on amd64. Employ the "Self Snoop" feature supported by some x86 processors to avoid cache flushes in the pmap.

* | dtrace_gethrtime: improve scaling of TSC ticks to nanosecondsAndriy Gapon2009-07-152-4/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently dtrace_gethrtime uses formula similar to the following for converting TSC ticks to nanoseconds: rdtsc() * 10^9 / tsc_freq The dividend overflows 64-bit type and wraps-around every 2^64/10^9 = 18446744073 ticks which is just a few seconds on modern machines. Now we instead use precalculated scaling factor of 10^9*2^N/tsc_freq < 2^32 and perform TSC value multiplication separately for each 32-bit half. This allows to avoid overflow of the dividend described above. The idea is taken from OpenSolaris. This has an added feature of always scaling TSC with invariant value regardless of TSC frequency changes. Thus the timestamps will not be accurate if TSC actually changes, but they are always proportional to TSC ticks and thus monotonic. This should be much better than current formula which produces wildly different non-monotonic results on when tsc_freq changes. Also drop write-only 'cp' variable from amd64 dtrace_gethrtime_init() to make it identical to the i386 twin.

* | Build on Jeff Roberson's linker-set based dynamic per-CPU allocatorRobert Watson2009-07-14166-4307/+2491
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (DPCPU), as suggested by Peter Wemm, and implement a new per-virtual network stack memory allocator. Modify vnet to use the allocator instead of monolithic global container structures (vinet, ...). This change solves many binary compatibility problems associated with VIMAGE, and restores ELF symbols for virtualized global variables. Each virtualized global variable exists as a "reference copy", and also once per virtual network stack. Virtualized global variables are tagged at compile-time, placing the in a special linker set, which is loaded into a contiguous region of kernel memory. Virtualized global variables in the base kernel are linked as normal, but those in modules are copied and relocated to a reserved portion of the kernel's vnet region with the help of a the kernel linker. Virtualized global variables exist in per-vnet memory set up when the network stack instance is created, and are initialized statically from the reference copy. Run-time access occurs via an accessor macro, which converts from the current vnet and requested symbol to a per-vnet address. When "options VIMAGE" is not compiled into the kernel, normal global ELF symbols will be used instead and indirection is avoided. This change restores static initialization for network stack global variables, restores support for non-global symbols and types, eliminates the need for many subsystem constructors, eliminates large per-subsystem structures that caused many binary compatibility issues both for monitoring applications (netstat) and kernel modules, removes the per-function INIT_VNET_*() macros throughout the stack, eliminates the need for vnet_symmap ksym(2) munging, and eliminates duplicate definitions of virtualized globals under VIMAGE_GLOBALS.

When triggered, the bug would sometimes cause a panic when the TCP activity to an affected machine eventually slowed during a lull. The panic only occurs if INVARIANTS is compiled into the kernel, and has laid dormant for some time as a result of INVARIANTS being off by default except in FreeBSD-CURRENT. Switch to atomic operations in the locations where the variable is changed. Reads have not been updated to be protected by atomics, so there is a possibility of accounting errors in any given calculation where the variable is read. This is considered unlikely to occur in the wild, and will not cause serious harm on rare occasions where it does. Thanks to Robert Watson for debugging help.

The new name reflects the fact that there are machine-dependent memory attributes that have nothing to do with controlling the cache's behavior. Introduce vm_object_set_memattr() for setting the default memory attributes that will be given to an object's pages. Introduce and use pmap_page_{get,set}_memattr() for getting and setting a page's machine-dependent memory attributes. Add full support for these functions on amd64 and i386 and stubs for them on the other architectures. The function pmap_page_set_memattr() is also responsible for any other machine-dependent aspects of changing a page's memory attributes, such as flushing the cache or updating the direct map. The uses include kmem_alloc_contig(), vm_page_alloc(), and the device pager: kmem_alloc_contig() can now be used to allocate kernel memory with non-default memory attributes on amd64 and i386. vm_page_alloc() and the device pager will set the memory attributes for the real or fictitious page according to the object's default memory attributes. Update the various pmap functions on amd64 and i386 that map pages to incorporate each page's memory attributes in the mapping. Notes: (1) Inherent to this design are safety features that prevent the specification of inconsistent memory attributes by different mappings on amd64 and i386. In addition, the device pager provides a warning when a device driver creates a fictitious page with memory attributes that are inconsistent with the real page that the fictitious page is an alias for. (2) Storing the machine-dependent memory attributes for amd64 and i386 as a dedicated "int" in "struct md_page" represents a compromise between space efficiency and the ease of MFCing these changes to RELENG_7.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The D-cache flushing added here was to deal with I-cache incoherency observed on ia64. However, the problem was in the implementation of pmap_enter_object() for ia64: it was missing I-cache coherency logic for prefaulted pages. After this got added in rev 195625, testing showed that no D-cache flushing was required. The SIGILL that was observed on Book-E (see commit log for rev 192323) ended up not being related to I-cache incoherency, but was found to be caused by bad memory. This discovery further undermined the need for D-cache flushing in the NFS I/O code, triggering the reversal. Approved by: re (kensmith) Notes: svn path=/head/; revision=195631
* | In nvpair_native_embedded_array(), meaningless pointers are zeroed.Marcel Moolenaar2009-07-111-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The programmer was aware that alignment was not guaranteed in the packed structure and used bzero() to NULL out the pointers. However, on ia64, the compiler is quite agressive in finding ILP and calls to bzero() are often replaced by simple assignments (i.e. stores). Especially when the width or size in question corresponds with a store instruction (i.e. st1, st2, st4 or st8). The problem here is not a compiler bug. The address of the memory to zero-out was given by '&packed->nvl_priv' and given the type of the 'packed' pointer the compiler could assume proper alignment for the replacement of bzero() with an 8-byte wide store to be valid. The problem is with the programmer. The programmer knew that the address did not have the alignment guarantees needed for a regular assignment, but failed to inform the compiler of that fact. In fact, the programmer told the compiler the opposite: alignment is guaranteed. The fix is to avoid using a pointer of type "nvlist_t *" and instead use a "char *" pointer as the basis for calculating the address. This tells the compiler that only 1-byte alignment can be assumed and the compiler will either keep the bzero() call or instead replace it with a sequence of byte-wise stores. Both are valid.
