parameter. The new name better reflects what the function does and
how it is used. The last parameter was always FALSE.
Note: In theory, gcc would perform constant propagation and dead code
elimination to achieve the same effect as removing the last parameter,
which is always FALSE. In practice, recent versions do not. So, there
is little point in letting unused code pessimize execution.
to configure this correctly yields many watchdog timeouts even on lightly
loaded machines. This is a common complaint from users with Dell 1750
servers with built-in dual 5704 NICs.
magic from exec_setregs(). In set_mcontext() we now also don't have
to worry that we entered the kernel with more that 512 bytes of
dirty registers on the kernel stack. Note that we cannot make any
assumptions anymore WRT to NaT collection points in exec_setregs(),
so we have to deal with them now.
word between the 8139C+ and the 8169. The 8139C+ has a 'frame alignment
error bit' (bit 27) but the 8169 does not. Rather than simply mark this
bit as reserved, RealTek removed it completely and shifted the remaining
status bits one space to the left. This was causing rl_rxeofcplus()
to misparse the error and checksum bits.
To workaround this, rl_rxeofcplus() now shifts the rxstat word one
bit to the right before testing any of the status bits (but after
the frame length has been extracted).
the time the card is inserted and the time that the card is
configured. This can lead to interrupt storms. The O2Micro suggested
workaround is to route the card function interrupt to IRQ1. It
appears from my testing that this is an acceptable workaround for most
chipsets (there's still some issue with the ricoh chipset).
Also, only look at the NOT_A_CARD bit when the bridge tells us there's
a card present. At least one test caused this to be true after the
card was removed, but the author couldn't recreate it with the
workaround in place. The change is more conservative than the
previous code, but still has the work around that wasn't present in
the older code.
note the existence of the 8169S and 8110S components. (The 8169
is just a MAC, the 8169S and 8110S contain both a MAC and PHY.)
- Properly handle list and buffer addresses as 64-bit. The RX and
TX DMA list addresses should be bus_addr_t's. Added RL_ADDR_HI()
and RL_ADDR_LO() macros to obtain values for writing into chip
registers.
- Set a slightly different TIMERINT value for 8169 NICs for improved
performance.
- Change left out of previous commit log: added some additional
hardware rev codes for other 10/100 chips and for the 8169S/8110S
'rev C' gigE MACs.
BGE_MACSTAT_MI_COMPLETE bit in the MAC status register as a link
change indicator. We turn this bit on now because some of the newer
chips need it, but it usually just means that reading/writing
an MII/GMII register has completed, not that a link change has
occured.
the standard.
1) When the bridge tells us that we have a card that isn't recognized, we
use the force register to force the CV_TEST to run. This test causes the
bridge to re-evaluate the card. Once this re-evaluation process happens,
we get a new interrupt that may say it is ready to process. We try this up
to 20 times. Tests have shown that this appears to correctly reset the
'Unknown card type' problem that I saw on my Sony PCG-505TS.
2) Take a page from OLDCARD and always read the CSC register in the ISR.
Some TI (and it seems maybe Ricoh) chipsets require this to behave
properly. This work around appears to work due to some power management
protocols that were improperly implemented. Maybe it can be removed when
this driver supports the full PME# protocol described in the standards.
3) Minor additional debug printf when debugging is enabled.
4) Minor additional commentary for things that are obvious only after study.
# I'm committing this from my Sony PCG-505TS using shared PCI interrupts
# and NEWCARD, but there are some issues with the Ricoh bridge still, but
# at least now I can boot with the card inserted and have it work.
to acpidb. The same problem exists in iasl. Add JIT patching there
too.
Add a comment to both makefiles to increase the chance that both
kludges are removed when a real solution is committed.
a reference to the containing object. The purpose of the reference
being to prevent the destruction of the object and an attempt to free
the wired page. (Wired pages can't be freed.) Unfortunately, this
approach does not work. Some operations, like fork(2) that call
vm_object_split(), can move the wired page to a difference object,
thereby making the reference pointless and opening the possibility
of the wired page being freed.
A solution is to use vm_page_hold() in place of vm_page_wire(). Held
pages can be freed. They are moved to a special hold queue until the
hold is released.

This fixes the illegal instruction fault encountered when building

osunixxf.c on the fly. This avoids having to pull it from the vendor

This should hold until the real fix arrives.
this involves the sign-extension of the high and low "word". Both
of which are 32-bit. The bug is especially harmful on ia64, where
0x9fffffffe0000000 is a common address (base of register stack).
This was invariably displayed as 0xffffffffe0000000.
The sign-extension is fixed by using {b|l}e{16|32|64}dec() where
applicable. Since elfdump(1) is not a bootstrap tool, dependency
on these functions is not a problem.
