fixes PR#26246.
- if crc/len are wrong, be sure to noticed it failed
- in check_suffixes(), be sure not to underrun an array (from yamt)
- don't fail so badly on short header, from and fixes R#26242 (also
from yamt)
- more underrun avoidance in file_uncompress(). fixes PR#26241.
- check each gzip-part's length against the original and warn if it's
wrong. fixes part of PR#26233.
- check the input crc32. fixes the rest of PR#26233.
Note:
- I don't have any hardware docments for this device, so this driver might
have some odd descriptions guessed by results of try-and-errors.
(the only info I have is the Linux driver, but I think it doesn't describe
the hardware specifications very well anyway)
- All RX packets and most TX packets are copied from/to buffers in the driver
due to hardware restriction, so performance is not so good for now.
Maybe RX packets can be directly DMA'ed to mbufs by the same method used
of fxp(4), but the hardware seems to require 4kbyte aligned RX buffers.
- Multicast filter setup function is not tested yet (no info).
- Currently only tested on R5000 O2 with disabled L2 cache, so needs
more tests on other CPU (i.e. RM5200/R10000/R12000) models.
- Currently BUS_DMA_COHERENT is not used for the device control data DMA
to avoid performance issue on memcpy() against RX buffers, but it might be
problematic when L2 cache is enabled or on R10000 models.
i386/identcpu.c renders it counterproductive.
(this was the only use and the reason for the invention of the
SKIP_FUNCn quirk; it should probably be removed entirely).
across the "coma bug" workaround to avoid clearing the MAPEN bit if it
was originally set by firmware. This appears necessary for proper
functioning of SMM on Geode CPUs, and thus for proper emulation (ugh)
of access to certain PCI configuration registers or VGA register
spaces. With this change, VGA and soundblaster emulation work on Geode
NX1 systems.
This was also the underlying problem that led to the introduction of
the PCI_QUIRK_SKIP_FUNCn quirks in pci_quirks.c, which are no longer
necessary (and counterproductive if you want to use VGA or a
Geode-specific audio driver). See the thread "pci probe" on port-i386
in August 2003 (The Soekris 4801, apparantly the most popular
Geode-based NetBSD box, has neither VGA nor audio, which may explain
why this wasn't noticed at the time).
which is very handy on a laptop to control EST through another program that
you don't necessarily want to run as root (in my case, gkrellm).
The option's name is EST_FREQ_USERWRITE, and is disabled by default.
ioctl names. This makes sure that each program is built with its own
copy even if object directories are not used. This avoids build
failures when two or more make jobs are used in parallel.
