2008-01-28Fix e100 on systems that have cache incoherent DMADavid Acker
On the systems that have cache incoherent DMA, including ARM, there is a race condition between software allocating a new receive buffer and hardware writing into a buffer. The two race on touching the last Receive Frame Descriptor (RFD). It has its el-bit set and its next link equal to 0. When hardware encounters this buffer it attempts to write data to it and then update Status Word bits and Actual Count in the RFD. At the same time software may try to clear the el-bit and set the link address to a new buffer. Since the entire RFD is once cache-line, the two write operations can collide. This can lead to the receive unit stalling or interpreting random memory as its receive area. The fix is to set the el-bit on and the size to 0 on the next to last buffer in the chain. When the hardware encounters this buffer it stops and does not write to it at all. The hardware issues an RNR interrupt with the receive unit in the No Resources state. Software can write to the tail of the list because it knows hardware will stop on the previous descriptor that was marked as the end of list. Once it has a new next to last buffer prepared, it can clear the el-bit and set the size on the previous one. The race on this buffer is safe since the link already points to a valid next buffer and the software can handle the race setting the size (assuming aligned 16 bit writes are atomic with respect to the DMA read). If the hardware sees the el-bit cleared without the size set, it will move on to the next buffer and skip this one. If it sees the size set but the el-bit still set, it will complete that buffer and then RNR interrupt and wait.

2008-01-28sundance: SIOCDEVPRIVATE pollutionFrancois Romieu
To quote one of my favorite contemporary author: [include/linux/sockios.h] * THESE IOCTLS ARE _DEPRECATED_ AND WILL DISAPPEAR IN 2.5.X -DaveM */ #define SIOCDEVPRIVATE 0x89F0 /* to 89FF */ [...] Gentoo's snmpd trips up over this code when trying to figure if the driver supports the non-SIOCDEVPRIVATE API or not. One can argue over its choice of heuristic but there no reason to make ioctl more ugly than needed.

2008-01-28ixgbe: Fix copper PHY initialization codeAuke Kok
While cleaning up the internal API focussing on Fiber and CX4 code we found that I had broken the copper PHY initialization code. This patch restores the PHY-specific code. This is mostly uninteresting since no copper PHY boards are yet available. The changes have been tested against Fiber only as I do not even have copper PHY versions of 82598 macs. This change actually cleans up the API code a bit more and we lose some initialization code. A few PHY link detection helper lines of code have been snuck into this patch, as well as a read flush where it was suspected that this might cause issues.

2008-01-28e1000/e1000e: Move PCI-Express device IDs over to e1000eAuke Kok
e1000e will from now on support the PCI-Express adapters that previously were supported by e1000. This support means better performance and easier debugging from now on for both the old PCI-X/PCI hardware and PCI-Express adapters. This patch also moves 3 recently merged device IDs over to e1000e that are identical to quad-port versions of already existing dual port versions. With this last bit every former e1000 pci-e device should work now with e1000e. Here is a brief list of which gigabit driver to use with which adapter: e1000: 82540 -> 82547 e1000e: 82571 -> 82573 ich8, ich9 (82562 or 82566) es2lan (80003eslan) igb: (not yet merged, only available from e1000.sf.net) 82575 Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-01-28e1000e: Disable L1 ASPM power savings for 82573 mobile variantsAuke Kok
L1 ASPM link (pci-e link power savings) has significant benefits (~1W savings when link is active) but unfortunately does not work correctly on any of the chipsets that have 82573 on mobile platforms which causes various nuisances: - eeprom reads return garbage information leading to bad eeprom checksums - long ping times (up to 2 seconds) - complete system hangs (freeze/lockup) A lot of T60 owners have been plagued by this, but other mobile solutions also suffer from these symptoms. Disabling L1 ASPM before we activate the PCI-E link fixes all of these issues at the cost of some power consumption. Remove a workaround RDTR adjustment that is no longer needed with this new one.

2008-01-28sk98lin: kill bogus check and convert to use ARRAY_SIZE()Alejandro Martinez Ruiz
This converts uses of ARRAY_SIZE(), and while at it also kills unreachable code as far as I can say. I can't tell what was the author trying to do with the following check. First we have: PNMI_STATIC const SK_PNMI_STATADDR StatAddr[SK_PNMI_MAX_IDX][SK_PNMI_MAC_TYPES]; and then a check goes like this: if (SK_PNMI_MAX_IDX != (sizeof(StatAddr) / (sizeof(SK_PNMI_STATADDR) * SK_PNMI_MAC_TYPES))) with the second line being just ARRAY_SIZE(StatAddr), which will always return SK_PNMI_MAX_IDX, rendering the check useless.
