i82546 chip has 2 Gig-E interfaces in a single chip.
The main difference is these chips have a special handshaking protocol
for accessing the EEPROM (due to the shared nature on the i82546).
kern/16373.
- SiS 7012 support from kern/17716 submitted by Quentin Garnier.
- ICH4 support
- Experimental support for nForce MCP, AMD768 and AMD8111.
- Rename the short name for ICH3: "i830M" -> "ICH3"
Always init chip via I/O space.
Map only I/O registers we actually need.
Automatically detect if we need to do bswapping
Add (untested) code to use automagic bswap on CyberPro.
Report video memory amount.
Report if/how bswapping is done.
When initializing a TCP/IP context descriptor, even if a checksum
offload feature is not going to be used, the IPCSS and TUCSS fields
must be initialized.
the brgphy driver; all users of the BCM5400 and BCM5401 need
the DSP patch and the sledgehammer-reset-at-media-set-time.
Also add a DSP patch for the BCM5411 gleaned from Apple's
GMAC driver for Darwin.
Tested with a 3Com 3c996-T (BCM5700 + BCM5401).
* Fix outbound IPv4 header checksums (missing add of an offset).
* When enabling Rx TCP/UDP checksum offload, make sure that IPv4
header checksum Rx offload is enabled on the chip, as well.
* Bump the number of Rx descriptors from 128 to 256.
* Don't use a sliding Tx interrupt window. Instead, just do reap-behind
when we have <= 1/8 of our available descriptors in wm_start().
* Don't use Tx Queue Empty interrupts, and always set the Tx Interrupt
Delay bit in the Tx descriptor.
* In wm_intr(), always call wm_rxintr() and wm_txintr(), regardless of
their respective ISR bits being set. We're here, might as well do some
work.
* Adjust the Tx and Rx interrupt delay timer values. New values from
Intel's driver for FreeBSD via Allen Briggs.
With these changes, NetBSD can sustain > 900Mb/s userland to userland
*without* using TCP checksum offload using Intel PRO/1000 XT cards.
to enable 64-bit data transfers on 64-bit cards when plugged into
a 64-bit slot. Right know the Asante GigaNIX is listed in that
table.
Sigh, there is an EEPROM bit that can be used to detect 64-bit vs
32-bit cards. Unfortunately, at least 2 vendors of 32-bit cards
fail to clear the "DATA64_EN" bit in the EEPROM, which causes the
card to lose badly, because it still manages to detect that it's
plugged into a 64-bit PCI slot. Yay, stupid hardware vendors.
path: Instead of waiting for the if_snd queue to be drained before
giving ownership of the frist descriptor to the chip, do it after
sync'ing all the descriptors for a single packet.
* Get CFG_M64ADDR, CFG_T64ADDR, and CFG_DATA64_EN from the EEPROM.
Note, we still disable CFG_M64ADDR and CFG_T64ADDR later (XXX need
PCI bus capability flags for these).
* Print a message if we're in a 64-bit slot and 64-bit data is
disabled in the EEPROM. Make sure CFG_DATA64_EN is disabled if
we're not in a 64-bit slot.
-treat the builtin font like any other font at runtime
-for that, copy it to malloc()'d memory during attach()
-in early console initialization, if we have to consider a broken card
(VGA_CONSOLE_ATI_BROKEN_FONTSEL), copy the builtin font to another
location in font ram; the attach() code will do the rest
put the "quirk" code into effect again
bit and then read it back in a loop (with appropriate delays) waiting
for it to read back clear.
This fixes a problem where the bus would hang when bringing down
the interface or changing interface flags on a system with a
sufficiently fast CPU (e.g. 2GHz P4 Xeon).
found on many (all?) of PCI-based ATI graphics cards. It is fully optional
and can be enabled by adding `options VGA_CONSOLE_ATI_BROKEN_FONTSEL'
to config file.
- Temporarily remove `quirk' mechanism. Similar code already exists
in pci_quirks.c.
make the number of available font slots variable,
set up a "quirk" mechanism to tell the generic vga code about crippled
VGA adapters which ignore the "fontsel" TS register,
initiate the quirk table with an ATI chip which happened to be on a board
I tested with.
Afaik quite a number of ATI chips suffers from the "loaded fonts don't
work" problem - these should be added.
Bad side effect of my change: The builtin font will be kicked out
always if a VGA_CONSOLE_SCREENTYPE is specified which needs a loaded
font. In early console initialization, we don't know much about the
graphics card, so we have to assume the worst (ie ATI:-).
Written by Bill Paul for FreeBSD. This port started out with the
port done to OpenBSD by nate@openbsd.org, but ended up looking much
more like the port of the ti driver done by drochner@netbsd.org
(they are similar in structure).
int pci_set_powerstate(pci_chipset_tag_t pc, pcitag_t tag, int newstate)
set power state of the device to newstate.
int pci_get_powerstate(pci_chipset_tag_t pc, pcitag_t tag)
get current power state of the device.
In the future, these functions will be used for ACPI support.
to run ABOUT FIRMWARE at the first isp_reset call. We *do* check for
the registers being set with values which would tell us if there's
firmware running or not- but this seems to not always work. It's not
essential, so move on.
Using pdc202xx_setup_channel() for PDC20268 and newer is wrong, and will
cause trap trying to read from a non-existent register on some arches
(e.g. macppc).
pointed out by Makoto Fujiwara on port-macppc.
Reenable statistics interrupts, reading it as 16bit caused it to not be cleared,and thus the eventual interrupt to not be cleared (and this caused an
infinite loop in interrupt routine).
While I'm there count STE_CarrierSenseErrors as oerror (this is incremented
each time we try to send a packet and the link is down).
- when a transmit underrun occurs, only reset the transmit logic. This prevents
the link from going down at the MII level (the same logic can probably
be used for other transmit errors)
- set the urgent threshold to half the start threshold. From experiments
this helps a bit decreasing the number of underruns
Now that underruns don't cause the interface to stop for several seconds,
make back out the default transmit threshold to 128.
