| 2003-10-28 | Split pmap_remove_range() into its main loop and a new function, | Miod Vallat | |
| pmap_remove_pte(), which takes the va and a pte. Use pmap_remove_pte() instead of pmap_remove_range() in strategic places, in order to save some cycles by avoiding unnecessary pte address recomputations. pmap_remove_range() is still preferred for large amounts of memory, as it will skip empty segments. | |||
| 2003-10-28 | In pmap_remove_range(), be sure to propagate pvlist flags when removing | Miod Vallat | |
| the head entry. While there, invalidate the affected pte earlier for safety, and store its PG_U bit in the pvlist flags as well. And also get rid of a pdt table group leftover in pmap_collect(). | |||
| 2003-10-27 | Be sure to always have a valid faulting address when we send a signal | Miod Vallat | |
| to a process. | |||
| 2003-10-27 | Be sure to flush the entire va space in cpu_switch(). | Miod Vallat | |
| This used to work because the cmmu code is suboptimal at the moment. | |||
| 2003-10-27 | Remove dead code and polish comments | Miod Vallat | |
| 2003-10-24 | Remove dead code. | Miod Vallat | |
| 2003-10-24 | No \n in panic() messages... | Miod Vallat | |
| 2003-10-23 | Correctly recover from bus error during guarded_access() on 88110. | Miod Vallat | |
| 2003-10-23 | No dependency on NDART needed here. | Miod Vallat | |
| 2003-10-19 | Simplify pmap DEBUG test constructs. | Miod Vallat | |
| 2003-10-16 | Better DEBUG output. | Miod Vallat | |
| 2003-10-15 | Better reset code, even. | Miod Vallat | |
| 2003-10-15 | Do not assert SYSRST on 1x7 boards, if we are not a SYSCON, or unexpected | Miod Vallat | |
| collateral damage will happen. | |||
| 2003-10-13 | Get rid of the "page table group" stuff. "groups" used to be one logical page | Miod Vallat | |
| big anyways. However, getting rid of the various constants (expanding to 0 for logs and shifts, and 1 for size) allows us to do further simplifications in some pmap loops, as there is no risk anymore of address wrapround. While there, fix some typos and comments. | |||
| 2003-10-13 | Do not define LEDEBUG by default. | Miod Vallat | |
| 2003-10-11 | Better sync comment with reality after last commit. | Miod Vallat | |
| 2003-10-11 | Get rid of "union cpupid"; makes <machine/cpus.h> disappear as well. | Miod Vallat | |
| 2003-10-11 | Nuke trailing whitespace. | Miod Vallat | |
| 2003-10-11 | Page tables can be cached again on 187 and 188, as long as they are cached | Miod Vallat | |
| write through and global (for 188). | |||
| 2003-10-11 | Simplify DAE debug display. | Miod Vallat | |
| 2003-10-11 | Merge sclock and clock pseudo-devices. | Miod Vallat | |
| 2003-10-10 | In pmap_expand_kmap(), be sure to initialize new page tables. | Miod Vallat | |
| 2003-10-09 | Minor cpp changes to let all kernels in conf/ compile. | Miod Vallat | |
| 2003-10-08 | Sync VMEChip2 timer usage with mvme68k (i.e. make it slightly more sane). | Miod Vallat | |
| Also, use it even when the 1x7 is not a system controller - this does not matter. | |||
| 2003-10-08 | delay() is actually a void function. | Miod Vallat | |
| 2003-10-08 | Nivas had identified an 88200 specific bug, where flushes of a page or a | Miod Vallat | |
| segment would sometimes not work correctly, and he added a brutal workaround leading to non-optimal, but safe, cache handling. The problem affects 88200 rev 7 and 9, and is believed to affect all 88200 revisions (although 88204 seems to be unaffected). Unfortunately, this problem not only affects cache flushes, but also tlb invalidations. So add a similar workaround in cmmu_flush_remote_tlb(). | |||
| 2003-10-06 | Correctly handle sparse mappings in pmap_changebit() and pmap_testbit(). | Miod Vallat | |
| 2003-10-06 | More vm_offset_t removal I forgot to check in; spotted by deraadt@ | Miod Vallat | |
| 2003-10-05 | Bang head against wall, unbreak ddb, do not collect $2000, and go to sleep. | Miod Vallat | |
| 2003-10-05 | Oops, commited from the wrong tree | Miod Vallat | |
| 2003-10-05 | More cmmu routines cleanup: | Miod Vallat | |
| - remove unused routines (which were mostly here for debugging anyway) - do not include <machine/m88*.h> from <machine/cmmu.h> but rather only from the modules which need them - try to simplify the MVME187 codepath in the 8820x code, whenever possible | |||
| 2003-10-05 | Do not use empty No_SSBR and No_Precheck macros, but rather pass empty | Miod Vallat | |
| arguments to PREP*() macros. Slightly reorganize code in badaddr() - also do not make some internal labels unnecessarily visible from outside code. | |||
| 2003-10-05 | Kill vm_offset_t and vm_size_t, in favor of the [pv]addr_t and [pv]size_t | Miod Vallat | |
| typedefs. | |||
| 2003-10-05 | De-register | Miod Vallat | |
| 2003-10-05 | typos | Miod Vallat | |
| 2003-10-05 | Correct db_{read,write}_bytes prototypes and use the official ones. | Miod Vallat | |
| 2003-10-05 | Despite what the comments say, the instruction cache has never been turned on, | Miod Vallat | |
| since day one. It's never too late to fix it... | |||
| 2003-10-03 | Use the commen DMT constants, and try to provide at least as many information | Miod Vallat | |
| in "machine frame" than regdump() does. XXX this whole ddb/ directory needs a huge KNF spanking, badly | |||
| 2003-10-03 | Merge tty_attach() in ttymalloc() and tty_detach() in ttyfree(). The need for | Miod Vallat | |
| separate tty registering is gone now that sparc has switched to wscons, and this makes the code less error-prone. Also, remove tests for ttymalloc() failure, since it uses M_WAITOK. ok millert@ deraadt@, tested by various people as well besides me... | |||
| 2003-10-02 | Upon invoking the freshly loaded binary, populate registers via embedded asm | Miod Vallat | |
| statements, and be sure of what we get, rather than use "hinted" register local variables; bugcrt can now be compiled with compiler optimization enabled. | |||
| 2003-10-02 | Fix some DAE processing logic - the kernel would incorrectly end up retrying | Miod Vallat | |
| already processed, or unwanted, DAE in certain circumstances by mistake. | |||
| 2003-10-02 | Ack external interrupts before reenabling them on 187. | Miod Vallat | |
| 2003-10-02 | Round VM_MAX_KERNEL_ADDRESS to a page boundary. | Miod Vallat | |
| 2003-10-01 | Unused bits. | Miod Vallat | |
| 2003-10-01 | There is no point in chown/chmod outside the install target. | Miod Vallat | |
| 2003-10-01 | Compile kernel and bootblocks with -mmemcpy, to get rid of libgcc dependancy. | Miod Vallat | |
| Also, honor default compilation options in stand/ whenever possible. This requires an up-to-date compiler, but it's not exactly like many people are going to be affected by this change... | |||
| 2003-09-29 | Disable cache on page tables unconditionnaly, not only for MVME188: magically | Miod Vallat | |
| solves the last 187 issues... Although the slowdown is surprisingly small, this is only a temporary measure, there is room for improvement... | |||
| 2003-09-29 | Better use of phys_map_vaddr* (does not matter until we start using more than | Miod Vallat | |
| one cpu). | |||
| 2003-09-29 | avaliable -> available | Miod Vallat | |
| 2003-09-28 | Clean various MVME188 related routines, fixing typos and removing unnecessary | Miod Vallat | |
| diagnostic code in the process. | |||
