The RX overflow is reported in bit 2 on real hardware and Linux driver
for the same device already has this defined correctly.
This fixes frequent interrupt storms seen on RouterStation Pro boards.
Discussed with: gonzo
symbols resolving in DDB
- When zeroing .bss/.sbss do not round end address to page boundary,
it's not neccessary and might destroy data pased by trampoline or
boot loader
and deactivate_device
- Save state before attaching driver and restore it when
detaching
- Clear CLK bit after last bit of byte has been sent over
the bus providing falling edge for last byte in transfer
- Fix several places where CS0 was always assumed
- Add $FreeBSD$ to ar71xxreg.h
fixed-state media with parameters set via hints
and configure MAC accordingly to these parameters.
All the underlying PHY magic is done by boot manager
on startup. At the moment there is no proper way
to make active and control all PHYs simultaneously
from one MII bus and there is no way to associate
incoming/outgoing packet with specific PHY.
1) Adds future RMI directories
2) Places intr_machdep.c in specfic files.arch pointing to the generic
intr_machdep.c. This allows us to have an architecture dependant intr_machdep.c
(which we will need for RMI) in the machine specific directory
3) removes intr_machdep.c from files.mips
4) Adds some TARGET_XLR_XLS ifdef's for the machine specific intra_machdep.h. We
may need to look at finding a better place to put this. But first I want to
get this thing compiling.
- Get rid of arge_fix_chain, use m_defrag like if_vr
- Rework interrupt handling routine to avoid race that lead
to disabling RX interrupts
- Enable full duplex if requested
- Properly set station MAC address
- Slightly optimize RX loop
- Initialize FILTERMATCH and FILTERMASK registers as linux driver does
* In arge_attach(), hard reset the MAC blocks before configuring the MAC.
* In arge_reset_dma(), clear pending packet interrupts based off
the hardware counter instead of acking every packet in the ring,
as the hardware counter can exceed the ring size. If the reset
was successful the counters will be zero anyway.
* In arge_encap(), remove an unused variable.
* In arge_tx_locked(), remove redundant setting of the EMPTY flag as
the TX DMA engine sets it for us.
* In arge_intr(), remember to clear the interrupt status bits
relayed from arge_intr_filter().
* Handle RX overflow and TX underflow.
* In arge_tx_intr(), remember to unmask the TX interrupt bits
after processing them.
