aarch64/pmap(9): Teach pmap_protect about pmap_kenter_pa mappings. Pages mapped with pmap_kenter_pa are necessarily unmanaged, so there are no P->V records, and pmap_kenter_pa leaves pp->pp_pv.pv_va zero with no modified/referenced state. However, pmap_protect erroneously examined pp->pp_pv.pv_va to ascertain the modified/referenced state -- and if the page was not marked referenced, pmap_protect would clear the LX_BLKPAG_AF bit (Access Flag), with the effect that subsequent uses of the page fault and require a detour through pmap_fault_fixup. This caused problems for the kernel module loader: - When loading the text section, kobj_load first allocates kva with uvm_km_alloc(UVM_KMF_WIRED|UVM_KMF_EXEC), which creates ptes with pmap_kenter_pa. These ptes are writable, so we can copy the text section into them, and have LX_BLKPAG_AF set so there will be no fault when they are used by the kernel. - But then kobj_affix makes the text section read/execute-only (and nonwritable) with uvm_km_protect(VM_PROT_READ|VM_PROT_EXECUTE), which updates the ptes with pmap_protect. This _should_ leave LX_BLKPAG_AF set, but by inadvertently treating the page as managed when it should be unmanaged, pmap_protect cleared it instead. - Most of the time, clearing LX_BLKPAG_AF caused no problem, because pmap_fault_fixup would silently resolve it. But if a hard interrupt handler tried to use any page in the module's text (or rodata, I suspect) that was not yet fixed up, the CPU would fault and enter pmap_fault_fixup -- which would promptly crash (or hang) by trying to take the pmap lock in interrupt context, which is forbidden. I observed this by loading dtrace.kmod early at boot and trying to dtrace hard interrupt handlers. With this change, pmap_protect now recognizes wired mappings (as created by pmap_kenter_pa) before consulting pp->pp_pv.pv_va, and preserves then LX_BLKPAG_AF bit in that case. ok skrll

sys: Use membar_release/acquire around reference drop. This just goes through my recent reference count membar audit and changes membar_exit to membar_release and membar_enter to membar_acquire -- this should make everything cheaper on most CPUs without hurting correctness, because membar_acquire is generally cheaper than membar_enter.

Update to support EFI runtime outside the kernel virtual address space by creating an EFI RT pmap that can be activated / deactivated when required. Adds support for EFI RT to ARM_MMU_EXTENDED (ASID) 32-bit Arm machines. On Arm64 the usage of pmapboot_enter is reduced and the mappings are created much later in the boot process -- now in cpu_startup_hook. Backward compatiblity for KVA mapped RT from old bootaa64.efi is maintained. Adding support to other platforms should be easier as a result.

sys: Membar audit around reference count releases. If two threads are using an object that is freed when the reference count goes to zero, we need to ensure that all memory operations related to the object happen before freeing the object. Using an atomic_dec_uint_nv(&refcnt) == 0 ensures that only one thread takes responsibility for freeing, but it's not enough to ensure that the other thread's memory operations happen before the freeing. Consider: Thread A Thread B obj->foo = 42; obj->baz = 73; mumble(&obj->bar); grumble(&obj->quux); /* membar_exit(); */ /* membar_exit(); */ atomic_dec -- not last atomic_dec -- last /* membar_enter(); */ KASSERT(invariant(obj->foo, obj->bar)); free_stuff(obj); The memory barriers ensure that obj->foo = 42; mumble(&obj->bar); in thread A happens before KASSERT(invariant(obj->foo, obj->bar)); free_stuff(obj); in thread B. Without them, this ordering is not guaranteed. So in general it is necessary to do membar_exit(); if (atomic_dec_uint_nv(&obj->refcnt) != 0) return; membar_enter(); to release a reference, for the `last one out hit the lights' style of reference counting. (This is in contrast to the style where one thread blocks new references and then waits under a lock for existing ones to drain with a condvar -- no membar needed thanks to mutex(9).) I searched for atomic_dec to find all these. Obviously we ought to have a better abstraction for this because there's so much copypasta. This is a stop-gap measure to fix actual bugs until we have that. It would be nice if an abstraction could gracefully handle the different styles of reference counting in use -- some years ago I drafted an API for this, but making it cover everything got a little out of hand (particularly with struct vnode::v_usecount) and I ended up setting it aside to work on psref/localcount instead for better scalability. I got bored of adding #ifdef __HAVE_ATOMIC_AS_MEMBAR everywhere, so I only put it on things that look performance-critical on 5sec review. We should really adopt membar_enter_preatomic/membar_exit_postatomic or something (except they are applicable only to atomic r/m/w, not to atomic_load/store_*, making the naming annoying) and get rid of all the ifdefs.

remove KERNHIST_INIT_STATIC(). it stradles the line between usable early in boot and broken early in boot by requiring a partly static structure with another structure that must be present by the time any uses are performed. theoretically platform code could allocate a chunk while seting up memory and assign it here, giving a dynamic sizing for the entry list, but the reality is that all users have a statically allocated entry list as well. the existing KERNHIST_LINK_STATIC() is used in conjunction with KERNHIST_INITIALIZER() instead. this stops a NULL pointer deref when the _LOG() macro is called before the storage is linked in, which happens with GCC 10 on OCTEON with UVMHIST enabled, crashing in very early kernel init.

Otherwise, alias in virtual address results in inconsistent results, at least for applications that rewrite text of other process, e.g., GDB for arm32. Also, this hopefully fixes other unexpected failures due to alias. Confirmed that there's no observable regression in performance; difference in ``time make -j8'' for GENERIC64 kernel on BCM2837 with and without setting uvmexp.ncolors is within 0.1%. Thanks to ryo@ for discussion. Fix uvmexp.ncolors for some big.LITTLE configuration; it is uncertain which CPU is used as primary, and as a result, secondary CPUs can require larger number of colors. In order to solve this problem, update uvmexp.ncolors via uvm_page_recolor(9) when secondary CPUs are attached, as done for other ports like x86. Pointed out by jmcneill@, and discussed on port-arm@: http://mail-index.netbsd.org/port-arm/2020/07/03/msg006837.html Tested and OK'd by ryo@. Fix previous; add missing <uvm/uvm.h> include.

Part IV of ad's performance improvements for aarch64 - Implement pmap_growkernel(), and update kernel pmap's stats with atomics. - Then, pmap_kenter_pa() and pmap_kremove() no longer need to allocate memory nor take pm_lock, because they only modify L3 PTEs. - Then, pm_lock and pp_lock can be adaptive mutexes at IPL_NONE which are cheaper than spin mutexes. - Take the pmap's lock in pmap_extract() if not the kernel's pmap, otherwise pmap_extract() might see inconsistent state.

Add support for Branch Target Identification (BTI). On the executable pages that have the GP (Guarded Page) bit, the semantic of the "br" and "blr" instructions is changed: the CPU expects the first instruction of the jump/call target to be "bti", and faults if it isn't. We add the GP bit on the kernel .text pages (and incidentally the .rodata pages, but we don't care). The compiler adds a "bti c" instruction at the beginning of each C function. We modify the ENTRY() macros to manually add "bti c" in the asm functions. cpuswitch.S needs a specific change: with "br x27" the CPU expects "bti j", which is bad because the functions begin with "bti c"; switch to "br x16", for the CPU to accept "bti c". BTI helps defend against JOP/COP. Tested on Qemu.

use PMAP_PAGE_INIT() to initialize mutex in pmap_page. VM_MDPAGE_INIT() in pmap_free_pdp() had initialized pp_flags, so it unintentionally cleared PMAP_PAGE_FLAGS_PV_TRACKED. use PMAP_PAGE_INIT to avoid using PMAP_PAGE_FLAGS_PV_TRACKED. pointed out by tnn@, thanks

pmap_remove_all(): Return a boolean value to indicate the behaviour. If true, all mappings have been removed, the pmap is totally cleared out, and UVM can then avoid doing the work to call pmap_remove() for each map entry. If false, either nothing has been done, or some helpful arch-specific voodoo has taken place.

Provide generic start code that assumes the MMU is off and caches are disabled as per the linux booting protocol for ARMv6 and ARMv7 boards. u-boot image type should be changed to 'linux' for correct behaviour. The new start code builds a minimal "bootstrap" L1PT with cached access disabled and uses the same table for all processors. AP startup is performed in less steps and more code is written in C. The bootstrap tables and stack are placed into an (orphaned) section "_init_memory" which is given to uvm when it is no longer used. Various kernels have been converted to use this code and tested. Some boards were provided by TNF. Thanks! The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS kernels. The GENERIC kernel will also work on RPI2 using u-boot. Thanks to martin@ and aymeric@ for testing on parallella and nanosoc respectively

cleanup locore, and changed the way to map memories during boot. - add functions bootpage_enter() and bootpage_alloc() to adapt various layout of physical memory map. especially for 64bit physical memory layout. pmapboot_alloc() allocates pagetable pages from _end[]. - changed to map only the required amount for PA=VA identity mapping (kernel image, UART device, and FDT blob) with L2_BLOCK(2Mbyte). - changing page permission for kernel image, and making KSEG mapping are done at cpu_kernel_vm_init() instead of at locore. - optimize PTE entries with PTE Contiguous bit. it is enabled on devmap only for now. reviewed by skrll@, thanks.
