* Assume EGA/VGA cardSamuel Thibault2014-03-281-0/+3
| | | | | | | | CGA and MONO cards are more than hard to find nowadays, and some buggy BIOSes claim running them nowadays... * i386/i386at/kd.c (kd_xga_init): Do not handle CGA and MONO cases any more, which thus default to EGA/VGA.
* Really default to EGA/VGA on unknown CMOS valuesSamuel Thibault2014-03-281-2/+3
| | | | | * i386/i386at/kd.c (kd_xga_init): Use CM_EGA_VGA behavior as default case for unknown values of CMOS data.
* kern: fix formatting of multiboot modulesJustus Winter2014-03-261-7/+3
| | | | | | | | | | | | | Previously, bootstrap_create would print the multiboot modules with padding applied to the end of the line. As multiboot modules as used by the Hurd span more than one line. This makes the list of modules hard to read and it looks unclean, more like an accident. Furthermore, it is not clear what the intend of this was, as the padding is applied at the end of the line, with no further information printed thereafter. * kern/bootstrap.c (bootstrap_create): Remove variable maxlen and len, update printfs.
* include: make the memory_object_t types translation functions mutableJustus Winter2014-03-253-4/+38
| | | | | | | | | | | | | Make the intran, outtran and destructor functions mutable using preprocessor macros. Make it possible to inject imports using the MEMORY_OBJECT_IMPORTS macro. This way, userspace servers can provide their own translation functions. * include/mach/mach_types.defs (memory_object_t): Make the translation mutable using preprocessor macros. * include/mach/memory_object.defs: Likewise for the inlined type declarations. Honor MEMORY_OBJECT_IMPORTS. * include/mach/memory_object_default.defs: Likewise.

| | | | | | | | | | | | | | | | | | | | Previously, the error KERN_RESOURCE_SHORTAGE was not properly propagated. Found using the Clang Static Analyzer. * xen/block.c (device_open): Fix error handling, remove unused label. * xen/net.c (device_open): Likewise.
* | Fix overflowSamuel Thibault2014-03-221-1/+1
|/ | | | | | | | We were filling much more than the mapwindows array, thus overwriting in at least debugger variables. * i386/intel/pmap.c (pmap_bootstrap): Make sure to limit mapwindows initialization within PMAP_NMAPWINDOWS.
* Only complain once per boot about Xen console smashSamuel Thibault2014-03-201-1/+1

| * kern: fix mig_strncpyJustus Winter2014-02-261-16/+20
| | | | | | | | | | | | | | | | | | | | | | Previously, the function mig_strncpy would always zero-terminate the destination string. Make mig_strncpy behave like mig_strncpy and strncpy in the glibc. Also fix the implementation of mig_strncpy to return the length of the written string to align the implementation with the declaration in include/mach/mig_support.h. * kern/ipc_mig.c (mig_strncpy): Do not zero-terminate the destination string. Return length of destination string.
* | Keep two virtual pages as mapping windows to access physical memorySamuel Thibault2014-03-033-5/+127
|/ | | | | | | | | | | | | | | | | | PCI devices expose their memory etc. way beyond last_phys_addr. Userland drivers opening /dev/mem need to open those too, even if phystokv() will not work for them. * i386/intel/pmap.h (pmap_mapwindow_t): New type. (pmap_get_mapwindow, pmap_put_mapwindow): New prototypes. (PMAP_NMAPWINDOWS): New macro. * i386/intel/pmap.c (mapwindows): New array. (pmap_get_mapwindow, pmap_put_mapwindow): New functions. (pmap_bootstrap, pmap_virtual_space): Reserve virtual pages for the mapping windows. * i386/i386/phys.c: Include <i386/model_dep.h> (INTEL_PTE_W, INTEL_PTE_R): New macros (pmap_zero_page, pmap_copy_page, copy_to_phys, copy_from_phys): Use `pmap_get_mapwindow' to temporarily map physical pages beyond last_phys_addr.

| * vm: trigger garbage collection on kernel memory pressureRichard Braun2014-02-061-3/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | In addition to physical pages, the slab allocator also consumes kernel virtual memory, so reclaim pages on failure to allocate from a kernel map. This method isn't foolproof but helps alleviate fragmentation. * vm/vm_kern.c (kmem_alloc): Call slab_collect and retry allocation once on failure. (kmem_realloc): Likewise. (kmem_alloc_wired): Likewise. (kmem_alloc_wired): Likewise. (kmem_alloc_aligned): Likewise.
