bus_space_tag_t's in pckbc_is_console() and vga_is_console(), and MI
code should never do such a thing, so don't do it.
tcic2.c: #if 0 some diagnostic code that compares two bus_space_tag_t's.
for "comparing" two bus_space_tag_t's. It is always true.
Everywhere that com(4) compares two tags, it compares to I/O base
addresses, too; comparing the base addresses should suffice.
TBD Clean this up more thoroughly.
Register if the PCI BAR is the memory-mapped type. The driver used to
decide whether to activate memory-mapped access by testing the truth of
pci_attach_args.pa_memt; that isn't MI, and it doesn't make sense.
pcdisplay.c: #if 0 some code that compares two bus_space_tag_t's
in order to see if pcdisplay0 is console. It does not seem to
be helpful to compare the tags; maybe the author intended to
compare some other bus property?
MI code should not compare an opaque type such as bus_space_tag_t!
handler! Stops a crash on the HP Pavilion N3270.
Cosmetic: sc->ih is a pointer, so set to NULL instead of 0. Compare
with NULL instead of testing truth.
respect the alignment in the ELF phdr.
Also, for correctness, use the maximum alignment of the PT_LOAD
sections rather than just the first one found.
Also, use more meaningful types.
it's perfectly valid for bus_dmamap_create() to do so (a contigous
transfers will then split in multiple segment).
Fix _xen_bus_dmamem_alloc_range() and _bus_dmamem_alloc_range() to
allow a boundary limit smaller than size:
- compute appropriate boundary for uvm_pglistalloc(), wich doesn't
accept boundary < size
- also take care of boundary when deciding to start a new segment.
While there, remove useless boundary argument to _xen_alloc_contig().
Fix the boundary-related issue of PR port-amd64/42980
- Do not use headers as example for .Aq, they should be marked up with
.In
- Drop the use of .Xo/.Xc
- Make sure to quote .Sh as argument to .Bl. groff warns about the list
otherwise and the size computation was off anyway as the string is
used as literal later.
(and silently) check for presence of media. While this would be easy
to implement via SCIOCCOMMAND, our kernel has quirks for this
command, which otherwise would not be readily available to userland
applications.
psc_pwrmgmt_csr_reg was never initialized to the actual offset of the
PCI PMCSR! Just delete psc_pwrmgmt_csr_reg and all uses of it. In
this way, fxp_pci_disable() becomes a no-op, so delete it, too.
initialization of sysmon_envsys(9), otherwise, if _STA does not return true
during the attachment of the driver, it is possible that a flag is never
set. This flaw has always been present, but it only got exposed after the
conversion to use the sysmon-limits.
