This is not a problem other than it's contrary to what alpha_softint_dispatch() expect, so make alpha_softint_return() go to IPL_HIGH before it does anything else.

qemu_find_rootdev(): Zero the buffer that we use to fetch the Qemu
"prom" root device variable; junk past the trailing NUL would cause
the way we parse the string to fail. Also parse rootdev= and root=
the same way ("be liberal in what you accept" approach).

Module Name:src Committed By: thorpej Date: Sun May 23 19:13:27 UTC 2021 Modified Files: src/sys/arch/alpha/alpha: pmap.c Log Message: Fix a bug in pmap_tlb_shootdown_all_user(), where it was not stashing away the pointer to the pmap in the TLB context structure like pmap_tlb_shootdown() was doing. This would result in the following failure scenario: - Page fault handler calls pmap_enter() to map a page. Mapping is the first one for that L2 PT L3 PT, meaning that an L2 PT and an L3 PT must be allocated. - L2 PT allocation succeeds. - L3 PT allocation fails under memory pressure. - pmap_enter() goes to drop the reference on the L2 PT, which, because it was the first of its mappings, frees the L2 PT. Becuse PALcode may have already tried to service a TLB miss though that L2 PT, we must issue an all-user-VA shootdown, and call pmap_tlb_shootdown_all_user() to do so. - pmap_tlb_shootnow() is called and an assert fires because the TLB context structure does not point to a pmap. This did not fail in the pmap_remove() scenario because the TLB context would have already had at least one call to pmap_tlb_shootdown(), which was initializing the pmap pointer properly.

Module Name:src Committed By: thorpej Date: Mon Jul 5 10:00:22 UTC 2021 Modified Files: src/sys/arch/alpha/alpha: pmap.c Log Message: Fix a bug introduced in pmap.c,v 1.287 where, when creating the PTE in pmap_enter(), we would erroneously disregard MOD/REF attributes already present on the page, thus causing FOW/FOR to be set incorrectly. Normally this is not a big problem (an extra page fault will be taken to resolve it), but if you access the mapping in interrupt context (such as during IDE PIO, for example), a KASSERT can fire due to acquiring an rwlock in interrupt context while servicing that fault.

Log Message:
- In unaligned_fixup(), use defined constants for opcodes, not magic numbers.
- In handle_opdec(), use ufetch_int() to fetch the instruction and
_u{fetch,store}_{8,16}() when emulating BWX instructions rather
than copyin() / copyout() (they're faster).
- Add event counters for BWX instruction emulation.

Module Name:src Committed By: thorpej Date: Sun Aug 16 18:05:52 UTC 2020 Modified Files: src/sys/arch/alpha/alpha: vm_machdep.c Log Message: In cpu_lwp_fork(), make sure that the PTBR field in l2's HWPCB references the lev1map associated with l2's pmap. Otherwise, the first time we SWPCTX to l2, we'll be on l1's page tables until the first pmap_activate() call for l2.

Module Name:src Committed By: thorpej Date: Sun Aug 16 20:04:36 UTC 2020 Modified Files: src/sys/arch/alpha/alpha: pmap.c Log Message: - Undo part of rev 1.264; go back to not acquiring the pmap lock in pmap_activate(). As of rev 1.211, the pmap::pm_lev1map field is stable across the life of the pmap, and so the conditino that the change in 1.264 was intended to avoid would not have happened anyway. - Explicitly use __cacheline_aligned / COHERENCY_UNIT rather than 64 in a couple of places. - Update comments around the lev1map lifecycle, and add some assertions to enforce the assumptions being described. - Remove some dubious DEBUG tests that are not MP-safe. - Chage some long-form #ifdef DIAGNOSTIC checks / panics to KASSERTs. - Remove the PMAP_ACTIVATE() macro because it's no longer used anywhere except for pmap_activate(). Just open-code the equivalent there. - In pmap_activate(), only perform the SWPCTX if either the PTBR or the ASN are different than what the PCB already has. Also assert that preemption is disabled and that the specified lwp is curlwp. - In pmap_deactivate(), add similar assertions, and add a comment explaining why a SWPCTX to get off of the deactivated lev1map is not necessaray. - Refactor some duplicated code in pmap_growkernel() into a new pmap_kptpage_alloc() function. - In pmap_growkernel(), assert that any user pmap published on the all-pmaps list does not reference the kernel_lev1map. - In pmap_asn_alloc(), get out early if we're called with the kernel pmap, since all kernel mappings are ASM. Remove bogus assertions around the value of pmap::pm_lev1map and the current ASN, and simply assert that pmap::pm_lev1map is never kernel_lev1map. Also assert that preemption is disabled, since we're manipulating per-cpu data structures. - Convert the "too much uptime" panic to a simple KASSERT, and update the comment to reflect that we're only subject to the longer 75 billion year ASN generation overflow (because CPUs that don't implement ASNs never go through this code path).

Module Name:src Committed By: thorpej Date: Sat Aug 29 15:16:12 UTC 2020 Modified Files: src/sys/arch/alpha/alpha: prom.c Log Message: Make sure init_prom_interface() only runs once, otherwise we initialize a mutex twice, and that upsets LOCKDEBUG. But instead of seeing a proper message about it, the output happens before the PROM console interfcace is initialized, we would end up with a translation fault back into SRM.

Module Name:src Committed By: thorpej Date: Sun Aug 30 16:26:56 UTC 2020 Modified Files: src/sys/arch/alpha/alpha: prom.c Log Message: When initializing the PROM interface, check to see if we're running inside Qemu by consulting the system serial number, and quickly abort calls into the PROM if we are. This is a temporary measure until I can figure out why calling into the Qemu PROM interface blows up.
