* MFC 288371:John Baldwin2015-11-051-1/+0
| | | | | | | | | | | | | | | | | | | When XSAVE support was added on amd64, the FPU save area was moved out of 'struct pcb' and into a variable-sized region after the structure. The kgdb code currently only reads the pcb. It does not read in the FPU save area but instead passes stack garbage as the FPU's saved context. Fixing this would mean determining the proper size of the area and fetching it. However, this state is not saved for running CPUs in stoppcbs[], so the callback would also have to know to ignore those pcbs. Instead, just remove the call since it is of limited usefulness. It results in kgdb reporting the state of the FPU/SIMD registers in userland, not their current values in the kernel. In particular, it does not report the correct state for any code in the kernel which does use the FPU and would report incorrect values in that case. Notes: svn path=/stable/9/; revision=290413

| | | | | | | | | | | | | | | | Add a new knob WITH_DEBUG_FILES to control the building of standalone debug files for userland programs and libraries. The "-g" debug flag is automatically applied when WITH_DEBUG_FILES is set. The debug files are named ${prog}.debug and ${shlib}.debug for consistency with other systems and documentation. In addition they are installed under /usr/lib/debug, to simplify the process of installing them if needed after a crash. Users of bsd.{prog,lib}.mk outside of the base system place the standalone debug files in a .debug subdirectory. GDB automatically searches both of these directories for standalone debug files.

* Commit the support for removing cpumask_t and replacing it directly withAttilio Rao2011-05-051-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cpuset_t objects. That is going to offer the underlying support for a simple bump of MAXCPU and then support for number of cpus > 32 (as it is today). Right now, cpumask_t is an int, 32 bits on all our supported architecture. cpumask_t on the other side is implemented as an array of longs, and easilly extendible by definition. The architectures touched by this commit are the following: - amd64 - i386 - pc98 - arm - ia64 - XEN while the others are still missing. Userland is believed to be fully converted with the changes contained here. Some technical notes: - This commit may be considered an ABI nop for all the architectures different from amd64 and ia64 (and sparc64 in the future) - per-cpu members, which are now converted to cpuset_t, needs to be accessed avoiding migration, because the size of cpuset_t should be considered unknown - size of cpuset_t objects is different from kernel and userland (this is primirally done in order to leave some more space in userland to cope with KBI extensions). If you need to access kernel cpuset_t from the userland please refer to example in this patch on how to do that correctly (kgdb may be a good source, for example). - Support for other architectures is going to be added soon - Only MAXCPU for amd64 is bumped now The patch has been tested by sbruno and Nicholas Esborn on opteron 4 x 12 pack CPUs. More testing on big SMP is expected to came soon. pluknet tested the patch with his 8-ways on both amd64 and i386.

This replaces MACHINE_ARCH=mipse[lb] TARGET_ABI=n64. MACHINE_ARCH=mipsn32e[lb] has been added, but currently requires WITHOUT_CDDL due to atomic issues in libzfs. I've not investigated this much, but implemented this to preserve as much of the TARGET_ABI functionality that I could. Since its presence doesn't affect the working cases, I've kept it in for now. Added mips64e[lb] to make universe, so more kernels build. And I think this (finally) closes the curtain on the tbemd tree. Notes: svn path=/head/; revision=217123

In order to do that, and in order to avoid KBI breakage with existing infrastructure the following semantic is implemented: - For live programs, a new member to the PT_LWPINFO is added (pl_tdname) - For cores, a new ELF note is added (NT_THRMISC) that can be used for storing thread specific, miscellaneous, informations. Right now it is just popluated with a thread name. GDB, then, retrieves the correct informations from the corefile via the BFD interface, as it groks the ELF notes and create appropriate pseudo-sections.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TARGET_BIG_ENDIAN is now completely dead, except where it was originally supposed to be used (internally in the toolchain building). TARGET_ARCH has changed in three cases: (1) Little endian mips has changed to mipsel. (2) Big endian mips has changed to mipseb. (3) Big endian arm has changed to armeb. Some additional changes are needed to make 'make universe' work on arm and mips after this change, so those are commented out for now. UPDATING information will be forthcoming. Any remaining rough edges will be hammered out in -current. Notes: svn path=/head/; revision=215082

| | | | | | | | | | | | | | | | Unlike for modules with dso type, in elf object modules all the sections have virtual address of zero. So, it is insufficient to add module base address to section virtual address (as recorded in section header) to get section address in kernel memory. Instead, we should apply the same calculations that are performed by kernel loaders (in boot code and in kernel) when they lay out sections in memory.
