2012-04-08Prevent repeated freeing of pager's mapMaksym Planeta
* mach-defpager/default_pager.c (pager_truncate): Do not set old_size to PAGEMAP_ENTRIES, to avoid freeing again just below.
2012-04-08Add appropriate checks to take into account that pager's memory map could be ↵Maksym Planeta
sparse. * mach-defpager/default_pager.c (pager_truncate, pager_read_offset, pager_release_offset, pager_dealloc, pager_realloc): Add checks for map field being NULL. (pager_dealloc): Set map pointer to zero.
2012-04-08Set size of object, when it is created.Maksym Planeta
* mach-defpager/default_pager.c (S_default_pager_object_create): Set pager limit to the given size.
2012-04-08Add support for objects that are not bounded to page size.Maksym Planeta
* mach-defpager/default_pager.c (struct dpager): Add new field. (seqnos_memory_object_data_write): If pager is not bounded to page size, than round it up. (seqnos_memory_object_lock_completed): Function is not in use anymore. (S_default_pager_object_set_size): Proceed object with any size correctly.
2012-04-08Add support for empty memory objects.Maksym Planeta
* mach-defpager/default_pager.c (pager_extend): When old_size is 0, use 1 to compute power of two above it. (pager_truncate): Do not avoid new_size being 0.
2012-04-08Add support for new pageout interface for defpager.Maksym Planeta
* mach-defpager/default_pager.c: (seqnos_memory_object_init, seqnos_memory_object_data_request): Use new interface. (seqnos_memory_object_data_return): Proceed request correctly.
2012-04-08Update debugging macros definitions and remove debugging macros when it becomesMaksym Planeta
hard to read the code. * mach-defpager/default_pager.c (dprintf, ddprintf): Change macros to make them more easy to use. (pager_port_lock, pager_port_unlock, seqnos_memory_object_data_write, pager_write_offset): Remove debugging messages (that are not shown at the moment) when it becomes hard to read the code.

* mach-defpager/default_pager.c (seqnos_memory_object_data_return): Add comment.
2012-03-26Correct function calling.Maksym Planeta

2011-11-20Just destroy port rights in default_pagerSergio Lopez
* mach-defpager/default_pager.c (seqnos_memory_object_terminate): Simply call `mach_port_destroy' instead of managing rights through `mach_port_mod_refs'.
2011-11-20Fix defpager into using the correct control portMaksym Planeta
The reply_port is only the correct control port when RPCs are from the kernel, not from e.g. tmpfs, such as default_pager_object_set_size calls. * mach-defpager/default_pager.c (seqnos_memory_object_terminate, S_default_pager_object_set_size): Make default pager use its own memory object control ports for external objects, remove reply_to parameter. * trans/proxy-defpager.c (S_default_pager_object_set_size): Remove reply_to parameter. * hurd/default_pager.defs (default_pager_object_set_size): Remove unused parameter.

2001-06-05* setup.c (page_read_file_direct): Fix logic to find the run thatMark Kettenis
contains the data to be read. Use size in bytes instead of blocks when calling device_read. (page_write_file_direct): Fix logic to find the run that contains the data to be written. Pass SIZE_WRITTEN to device_write call instead of &WROTE when writing a whole page. Correctly calculate SEGSIZE.

2001-02-282000-12-28 Roland McGrath <roland@frob.com>Roland McGrath
Override the shared code from serverboot for device access with a new, simpler implementation with no filesystem format support. The new code implements the new default_pager_paging_storage RPC to set up paging areas that can be subsets of whole Mach devices, with no Linux signature checking. The compatibility setup entry point works as before on whole devices. * setup.c, file_io.h: New files. * Makefile (SRCS): Remove def_pager_setup.c, file_io.c, strfcns.c, ext2_file_io.c, ffs_file_io.c, ffs_compat.c, minix_file_io.c, minix_ffs_compat.c; add setup.c to replace them all.

* Makefile: Move include ../Makeconf earlier, since it sets srcdir.

* Makefile, main.c: New files for new this directory `mach-defpager'. This is a standalone Hurd program version of the Mach default pager, with the bulk of the source code coming from ../serverboot. This program /hurd/mach-defpager is started like a normal daemon, i.e. from rc or whatever, rather than being the first task. * ChangeLog: New file, mentioning itself in this sentence.
