- include <bsd.init.mk> now that we can do it, because we need Makefile.rump
to be included first, so that NOLINT gets defined, so that we don't end up
building lint modules just for this.
inspire the GCC_NO_* series of variables, and explain some
about what the issues may be for each, hopefully providing some
direction on how to fix new warnings in this space.
christos asked me for this last year, and it's finally complete
enough to commit. :-)
so that when this code accesses mem_clustes[0] and mem_clusters[1]
it does't reach out of bounds.
XXX: should be in a header, but it's ugly to fix and i stopped
when bus_dma.c wouldn't build.
returns ENOMEM in addition to EAGAIN.
Device-dependent start() routine may allocate buffer directly, or via
bus_dma(9) API (some implementations for bus_dma(9) like alpha allocate
memory internally).
If these attempts fail with ENOMEM, this is not a disk error, therefore
we must retry later, as already done for EAGAIN.
called with cpu_intr_p() is turning on, if used from the interrupt context.
Otherwise, entropy_enter() is used instead of entropy_enter_intr(), which
results in KASSERT() failure.
Therefore, bump ci_intrdepth for clock interrupt. Remove stale comment also.
sleep in pmap_enter(9) and pmap_kenter_pa(9), which can result in dead lock.
In most cases, pmap_enter(9) is used with PMAP_CANFAIL flag. In this case,
if pte_enter() fails due to uvm_km_alloc(9), we can safely return ENOMEM.
UVM layer will take care of it.
uvm_km_alloc(9) fails for pmap_enter(9) without PMAP_CANFAIL or for
pmap_kenter_pa(9), we have no choice but to panic there.
However, my testbeds for 403 and 405 survive more than a week at least
without hitting this panic.
- Add "static inline" to pte_enter(), to match with its declaration.
- Remove parentheses from return.
- Use NULL instead of 0 for pointer initialization.
No binary changes.
The list of available letters for the command line options gets shorter
and shorter. Most of the interesting letters are already used for some
warning categories. Curiously, -A, -W and -E were all still available.
The option -A nicely matches the intention of the option, which is to
allow a certain set of language features. To keep the option available
for further extensions, define -Ac11 as the currently only valid option
of that kind. This allows straight-forward extension for C17 and future
language standards, as well as independent feature-sets. The options -W
and -E may someday complement the -A option, using the allow/warn/error
categories.
No special handling is necessary for C90 since none of the struct
members is a const_member.
The prefix 'Var' is not necessary since this type does not apply to a
variable but only to a modifier.
No functional change.
