Hello everyone, I'm resurrecting this thread because it appears we'll need to support these motherboards for several months to come, yet Adrian Bunk has scheduled the removal of eepro100 in January 2007. To recap, we have to support ~30 EBC-2000T motherboards. http://www.adlinktech.com/PD/web/PD_detail.php?pid=213 These motherboards come with three on-board Intel 82559 NICs. Last time I checked, i.e. two months ago, e100 did not correctly initialize all three NICs on these motherboards. Therefore, we've been using eepro100. I will be testing the latest 2.6.20 kernel to see if the situation has changed, but I wanted to let you all know that there are still some eepro100 users out there, out of necessity.

John, I've made this patch against 2.6.20 to enable IO access for e100, in the hope it might change something with the timings. I smoke tested it against one e100 in one of my machines, and I disabled the Mem bit in the COMMAND register after loading the driver to make sure that it wasn't using memory access to the registers. Please test with insmod e100.ko use_io=1 The patch is actually short, considering the magnitude of the change, its inline and attached in case my mailer corrupts it. Please let me know if it changes something, I still believe this is something very specific to your systems (or more likely the eeprom on your systems) == begin patch == e100: try using io only Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> --- drivers/net/e100.c | 74 ++++++++++++++++++++++++++++------------------------ 1 files changed, 40 insertions(+), 34 deletions(-) diff --git a/drivers/net/e100.c b/drivers/net/e100.c index 0cefef5..df3d2e7 100644 --- a/drivers/net/e100.c +++ b/drivers/net/e100.c @@ -159,7 +159,7 @@ #include <asm/unaligned.h> #define DRV_NAME "e100" #define DRV_EXT "-NAPI" -#define DRV_VERSION "3.5.17-k2"DRV_EXT +#define DRV_VERSION "3.5.17-k2_iodebug"DRV_EXT #define DRV_DESCRIPTION "Intel(R) PRO/100 Network Driver" #define DRV_COPYRIGHT "Copyright(c) 1999-2006 Intel Corporation" #define PFX DRV_NAME ": " @@ -174,10 +174,13 @@ MODULE_VERSION(DRV_VERSION); static int debug = 3; static int eeprom_bad_csum_allow = 0; +static int use_io = 0; module_param(debug, int, 0); module_param(eeprom_bad_csum_allow, int, 0); +module_param(use_io, int, 0); MODULE_PARM_DESC(debug, "Debug level (0=none,...,16=all)"); MODULE_PARM_DESC(eeprom_bad_csum_allow, "Allow bad eeprom checksums"); +MODULE_PARM_DESC(use_io, "Force use of i/o access mode"); #define DPRINTK(nlevel, klevel, fmt, args...) \ (void)((NETIF_MSG_##nlevel & nic->msg_enable) && \ printk(KERN_##klevel PFX "%s: %s: " fmt, nic->netdev->name, \ @@ -591,7 +594,7 @@ static inline void e100_write_flush(stru { /* Flush previous PCI writes through intermediate bridges * by doing a benign read */ - (void)readb(&nic->csr->scb.status); + (void)ioread8(&nic->csr->scb.status); } static void e100_enable_irq(struct nic *nic) @@ -599,7 +602,7 @@ static void e100_enable_irq(struct nic * unsigned long flags; spin_lock_irqsave(&nic->cmd_lock, flags); - writeb(irq_mask_none, &nic->csr->scb.cmd_hi); + iowrite8(irq_mask_none, &nic->csr->scb.cmd_hi); e100_write_flush(nic); spin_unlock_irqrestore(&nic->cmd_lock, flags); } @@ -609,7 +612,7 @@ static void e100_disable_irq(struct nic unsigned long flags; spin_lock_irqsave(&nic->cmd_lock, flags); - writeb(irq_mask_all, &nic->csr->scb.cmd_hi); + iowrite8(irq_mask_all, &nic->csr->scb.cmd_hi); e100_write_flush(nic); spin_unlock_irqrestore(&nic->cmd_lock, flags); } @@ -618,11 +621,11 @@ static void e100_hw_reset(struct nic *ni { /* Put CU and RU into idle with a selective reset to get * device off of PCI bus */ - writel(selective_reset, &nic->csr->port); + iowrite32(selective_reset, &nic->csr->port); e100_write_flush(nic); udelay(20); /* Now fully reset device */ - writel(software_reset, &nic->csr->port); + iowrite32(software_reset, &nic->csr->port); e100_write_flush(nic); udelay(20); /* Mask off our interrupt line - it's unmasked after reset */ @@ -639,7 +642,7 @@ static int e100_self_test(struct nic *ni nic->mem->selftest.signature = 0; nic->mem->selftest.result = 0xFFFFFFFF; - writel(selftest | dma_addr, &nic->csr->port); + iowrite32(selftest | dma_addr, &nic->csr->port); e100_write_flush(nic); /* Wait 10 msec for self-test to complete */ msleep(10); @@ -677,23 +680,23 @@ static void e100_eeprom_write(struct nic for(j = 0; j < 3; j++) { /* Chip select */ - writeb(eecs | eesk, &nic->csr->eeprom_ctrl_lo); + iowrite8(eecs | eesk, &nic->csr->eeprom_ctrl_lo); e100_write_flush(nic); udelay(4); for(i = 31; i >= 0; i--) { ctrl = (cmd_addr_data[j] & (1 << i)) ? eecs | eedi : eecs; - writeb(ctrl, &nic->csr->eeprom_ctrl_lo); + iowrite8(ctrl, &nic->csr->eeprom_ctrl_lo); e100_write_flush(nic); udelay(4); - writeb(ctrl | eesk, &nic->csr->eeprom_ctrl_lo); + iowrite8(ctrl | eesk, &nic->csr->eeprom_ctrl_lo); e100_write_flush(nic); udelay(4); } /* Wait 10 msec for cmd to complete */ msleep(10); /* Chip deselect */ - writeb(0, &nic->csr->eeprom_ctrl_lo); + iowrite8(0, &nic->csr->eeprom_ctrl_lo); e100_write_flush(nic); udelay(4); } }; @@ -709,21 +712,21 @@ static u16 e100_eeprom_read(struct nic * cmd_addr_data = ((op_read << *addr_len) | addr) << 16; /* Chip select */ - writeb(eecs | eesk, &nic->csr->eeprom_ctrl_lo); + iowrite8(eecs | eesk, &nic->csr->eeprom_ctrl_lo); e100_write_flush(nic); udelay(4); /* Bit-bang to read word from eeprom */ for(i = 31; i >= 0; i--) { ctrl = (cmd_addr_data & (1 << i)) ? eecs | eedi : eecs; - writeb(ctrl, &nic->csr->eeprom_ctrl_lo); + iowrite8(ctrl, &nic->csr->eeprom_ctrl_lo); e100_write_flush(nic); udelay(4); - writeb(ctrl | eesk, &nic->csr->eeprom_ctrl_lo); + iowrite8(ctrl | eesk, &nic->csr->eeprom_ctrl_lo); e100_write_flush(nic); udelay(4); /* Eeprom drives a dummy zero to EEDO after receiving * complete address.

I *do* monitor the mailing lists. ] I will try and summarize the problem as I understand it at this point. I've written two messages so far: http://groups.google.com/group/linux.kernel/msg/3a05d819c66474db http://groups.google.com/group/linux.kernel/msg/391aebbb3dfd6039 And here is a link to the complete thread: http://lkml.org/lkml/fancy/2006/11/3/124 I have a motherboard with three on-board 82559 NICs. o eepro100.ko properly initializes all three NICs o e100.ko fails to initialize one of them NOTE: With kernel 2.6.14, e100.ko fails to initialize the NIC with MAC address 00:30:64:04:E6:E4. With kernel 2.6.18 e100.ko fails to initialize the NIC with MAC address 00:30:64:04:E6:E5. The problem is not an incorrect checksum. (Donald Becker's dump utility reports a correct checksum for all three NICs.) The problem seems to be that e100.ko fails to read the contents of one of the EEPROMs. Auke wrote: > How did you do the first `ethtool` eeprom dump? did you have the > `e100` module loaded at that time? Did you use the new `override` > mechanism graciously donated by David M? These tests were performed on a 2.6.14 kernel. I hacked e100_eeprom_load() to return 0 even when the checksum fails. Thus the driver did not refuse to load, and I was able to use ethtool to dump the contents of the 3 EEPROMs. Here are additional examples running a 2.6.18.1-hrt kernel.

Intel 82559 EEPROM Map and Programming Information (AP-394) states: http://www.intel.com/design/network/applnots/ap394.htm The Standby Enable bit enables the 82559 to enter standby mode. When this bit equals 1b, the 82559 is able to recognize an idle state and can enter standby mode (some internal clocks are stopped for power saving purposes). The 82559 does not require a PCI clock signal in standby mode. If this bit equals 0b, the idle recognition circuit is disabled and the 82559 always remains in an active state. Thus, the 82559 always requests PCI CLK using the Clockrun mechanism. Auke, do you agree with Donald Becker's warning? If I disable STB, the NICs will waste a bit more power when idle, is that correct? Are there other implications? Thanks for reading this far!

Since something with this NIC specifically made the EEPROM return all 0xff's, the MAC address is automatically invalid, and thus probe fails. It seems that the driver has more problems with this NIC than just the eeprom checksum being bad. Needless to say this might need fixing. Can you load the eepro driver and send me the full eeprom dump? Perhaps I can duplicate things over here. [snip] > On a related note, I am concerned by this message: > > Sleep mode is enabled.

If you are using the e100 in a performance situation, I would certainly switch it off :) > If I disable STB, the NICs will waste a bit more power when idle, > is that correct? Are there other implications? hm, I don't know the power specs of e100 that well, so I can't say that it saves significant amounts of power, but I suspect it would. Power management on nics is hairy business. As suggested, it can take time before the nic powers back up, performance can be impacted, and some commands might return an invalid or unknown value. OTOH our labs here test these things pretty well before they get send out to customers and resales agents, so Beckers cautious wording catches the severity pretty well (recommended). I would say that under most circumstances, it's safe to enable STB, but you might want to disable it for use in routing and other server applications, where most of the time the NIC is active anyway. hth Auke > > Thanks for reading this far! > > John ^ permalink raw reply [flat|nested] 16+ messages in thread

Something is wrong in the driver, but I don't understand yet why it only affects one of the 3 nics in your system. > In 2.6.14.7, e100.ko fails to read the EEPROM on 0000:00:08.0 (eth0) > In 2.6.18.1, e100.ko fails to read the EEPROM on 0000:00:09.0 (eth1) almost sounds like a bug got fixed and it introduced a regression. this wouldn't be the right time to pull out git-bisect would it? even loading 2.6.15, 2.6.16, 2.6.17 on it would give us some good information.

I suspect that one reason beckers code works is that it uses IO based access (slower, and different method) to the adapter rather than memory mapped access. The second thought is that the adapter is in D3, and something about your kernel or the driver doesn't successfully wake it up to D0. An indication of this would be looking at lspci -vv before/after loading the driver. Also, after loading/unloading eepro100 does the e100 driver work? A third idea is look for a master abort in lspci after e100 fails to load. And a last idea is for us to instrument the reads /writes from/to the device during init and see if everything is returning 0xffffffff, as that indicates the I/O and/or memory bar is not enabled, or the address returned from ioremap is invalid.

On my NICs, the EEPROM ID (Word 0Ah) is set to 0x40a2. Thus DDPD (bit 6) is set to 0. DDPD is the "Disable Deep Power Down while PME is disabled" bit. 0 - Deep Power Down is enabled in D3 state while PME-disabled. 1 - Deep Power Down disabled in D3 state while PME-disabled. This bit should be set to 1b if a TCO controller is being used via the SMB because it requires receive functionality at all power states. Are you suggesting I try and set DDPD to 1?

This may be related but I doubt it. Something is strange about how memory is being mapped in your system. whatever is creating the problem moved when you changed the kernel version. I'm wondering if there is a device collision at e5302000.

There isn't one, MAbort+ would be showing in the above lspci output. The all 0xffffffff returns when you read registers is a sure sign the hardware either isn't at the address specified or is in a power down state.

I think you may have a piece of eeprom hardware that is either "slow" or slightly out of spec. I wonder if the hrt kernel makes udelay(4) much more like 4us than the regular kernels. can you try adding mdelay(100); in e100_eeprom_load before the for loop, and then change the multiple udelay(4) to mdelay(1) in e100_eeprom_read > On an unrelated note, insmod_100.txt is truncated at the beginning, and > insmod_110.txt is truncated in the middle (!!) cf. line 14.

That is very strange, I would think that maybe you have something else on the bus with the e100 that may be hogging bus cycles you have failing hardware (maybe a bad eeprom, or possibly a bad mac chip) > $ grep -c 0xFFFF insmod* > insmod_300.txt:0 > insmod_301.txt:0 > insmod_302.txt:0 > insmod_303.txt:0 > insmod_304.txt:0 > insmod_305.txt:0 > insmod_306.txt:0 > insmod_307.txt:0 > insmod_308.txt:0 > insmod_309.txt:0 > insmod_310.txt:0 > insmod_311.txt:0 > insmod_312.txt:1 > insmod_313.txt:5 > insmod_314.txt:24 > insmod_315.txt:45 > insmod_316.txt:243 > insmod_317.txt:256 > insmod_318.txt:256 > insmod_319.txt:256 > insmod_320.txt:256 > insmod_321.txt:256 > insmod_322.txt:256 > insmod_323.txt:253 > insmod_324.txt:240 this is even stranger, does it cycle back down (sine wave) to zero again? The delays did seem to work, at least sometimes. This indicates that something needs that extra delay to successfully read the eeprom. I might try changing all the udelay(4) to udelay(40) (x10 increase) and see if that gives you a happy medium of "most times driver loads without error" John, this problem seems to be very specific to your hardware. I know that you have put in a lot of time debugging this, but I'm not sure what we can do from here. If this were a generic code problem more people would be reporting the issue. What would you like to do? At this stage I would like e100 to work better than it is, but I'm not sure what to do next.
