* ps3disk.c: Rewrite ps3disk_transferChattrapat Sangmanee2025-01-241-41/+55
| | | | | | | | | | | | | | | | | | | | | This function is bugged since the beginning, but it never hit because its variable doesn't allow. However, since commit a77e1f0f81df5fa3b4a6a38728ebace599cb18a4 it happen now. First, it assume that ds_len will always equal to real user requested size. So it being used for sector count calculation. This is no longer true, and will fail if attempt to read last few sectors. Use bp->bio_length instead. Second, this being a loop is pointless because nsegs will never be > 1 as specified at bus_dma_tag_create() call. And all it doing is to repeat very same command again but with different ds_addr. Since bio_driver2 tag ident pointer are being reused, the result will be discarded at ps3disk_intr().

Since moea64 uses a second tier kobj as well, for its own private methods, this adds a second pmap install function (pmap_mmu_init()) to perform pmap 'post-install pre-bootstrap' initialization, before the IFUNCs get initialized.

* Extract eventfilter declarations to sys/_eventfilter.hConrad Meyer2019-05-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h" in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header pollution substantially. EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c files into appropriate headers (e.g., sys/proc.h, powernv/opal.h). As a side effect of reduced header pollution, many .c files and headers no longer contain needed definitions. The remainder of the patch addresses adding appropriate includes to fix those files. LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by sys/mutex.h since r326106 (but silently protected by header pollution prior to this change). No functional change (intended). Of course, any out of tree modules that relied on header pollution for sys/eventhandler.h, sys/lock.h, or sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

* powerpc: Fix regression introduced in r342771Conrad Meyer2019-01-071-2/+9
| | | | | | | | | | | | | | | | | | | | | In r342771, I introduced a regression in Power by abusing the platform smp_topo() method as a shortcut for providing the MI information needed for the stated sysctls. The smp_topo() method was already called later by sched_ule (under the name cpu_topo()), and initializes a static array of scheduler topology information. I had skimmed the smp_topo_foo() functions and assumed they were idempotent; empirically, they are not (or at least, detect re-initialization and panic). Do the cleaner thing I should have done in the first place and add a platform method specifically for core- and thread-count probing.

* Move the powerpc64 direct map base address from zero to high memory. ThisNathan Whitehorn2018-03-071-4/+2
| | | | | | | | | | | | | | | | | | | | | | accomplishes a few things: - Makes NULL an invalid address in the kernel, which is useful for catching bugs. - Lays groundwork for radix-tree translation on POWER9, which requires the direct map be at high memory. - Similarly lays groundwork for a direct map on 64-bit Book-E. The new base address is chosen as the base of the fourth radix quadrant (the minimum kernel address in this translation mode) and because all supported CPUs ignore at least the first two bits of addresses in real mode, allowing direct-map addresses to be used in real-mode handlers. This is required by Linux and is part of the architecture standard starting in POWER ISA 3, so can be relied upon.

* Always null-terminate ccb_pathinq.(sim_vid|hba_vid|dev_name)Alan Somers2017-01-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sim_vid, hba_vid, and dev_name fields of struct ccb_pathinq are fixed-length strings. AFAICT the only place they're read is in sbin/camcontrol/camcontrol.c, which assumes they'll be null-terminated. However, the kernel doesn't null-terminate them. A bunch of copy-pasted code uses strncpy to write them, and doesn't guarantee null-termination. For at least 4 drivers (mpr, mps, ciss, and hyperv), the hba_vid field actually overflows. You can see the result by doing "camcontrol negotiate da0 -v". This change null-terminates those fields everywhere they're set in the kernel. It also shortens a few strings to ensure they'll fit within the 16-character field.
