By changing the value of +* the literal in the instruction before the code is loaded, the +* driver can change the algorithm. +* +* INTDELAY - This loads the dead-man timer with its inital value. +* When this timer expires the interrupt is asserted, and the +* timer is reset each time a new packet is received. (see +* BUNDLEMAX below to set the limit on number of chained packets) +* The current default is 0x600 or 1536. Experiments show that +* the value should probably stay within the 0x200 - 0x1000. +* +* BUNDLEMAX - +* This sets the maximum number of frames that will be bundled. In +* some situations, such as the TCP windowing algorithm, it may be +* better to limit the growth of the bundle size than let it go as +* high as it can, because that could cause too much added latency. +* The default is six, because this is the number of packets in the +* default TCP window size. A value of 1 would make CPUSaver indicate +* an interrupt for every frame received. If you do not want to put +* a limit on the bundle size, set this value to xFFFF. +* +* BUNDLESMALL - +* This contains a bit-mask describing the minimum size frame that +* will be bundled. The default masks the lower 7 bits, which means +* that any frame less than 128 bytes in length will not be bundled, +* but will instead immediately generate an interrupt. This does +* not affect the current bundle in any way. Any frame that is 128 +* bytes or large will be bundled normally. This feature is meant +* to provide immediate indication of ACK frames in a TCP environment. +* Customers were seeing poor performance when a machine with CPUSaver +* enabled was sending but not receiving. The delay introduced when +* the ACKs were received was enough to reduce total throughput, because +* the sender would sit idle until the ACK was finally seen. +* +* The current default is 0xFF80, which masks out the lower 7 bits. +* This means that any frame which is x7F (127) bytes or smaller +* will cause an immediate interrupt. Because this value must be a +* bit mask, there are only a few valid values that can be used. To +* turn this feature off, the driver can write the value xFFFF to the +* lower word of this instruction (in the same way that the other +* parameters are used). Likewise, a value of 0xF800 (2047) would +* cause an interrupt to be generated for every frame, because all +* standard Ethernet frames are <= 2047 bytes in length. +*************************************************************************/ + +/* if you wish to disable the ucode functionality, while maintaining the + * workarounds it provides, set the following defines to: + * BUNDLESMALL 0 + * BUNDLEMAX 1 + * INTDELAY 1 + */ +#define BUNDLESMALL 1 +#define BUNDLEMAX (u16)6 +#define INTDELAY (u16)1536 /* 0x600 */ + + /* do not load u-code for ICH devices */ + if (nic->flags & ich) + goto noloaducode; + + /* Search for ucode match against h/w rev_id */ + for (opts = ucode_opts; opts->mac; opts++) { + int i; + u32 *ucode = opts->ucode; + if (nic->mac != opts->mac) + continue; + + /* Insert user-tunable settings */ + ucode[opts->timer_dword] &= 0xFFFF0000; + ucode[opts->timer_dword] |= INTDELAY; + ucode[opts->bundle_dword] &= 0xFFFF0000; + ucode[opts->bundle_dword] |= BUNDLEMAX; + ucode[opts->min_size_dword] &= 0xFFFF0000; + ucode[opts->min_size_dword] |= (BUNDLESMALL) ? 0xFFFF : 0xFF80; + + for (i = 0; i < UCODE_SIZE; i++) cb->u.ucode[i] = cpu_to_le32(ucode[i]); cb->command = cpu_to_le16(cb_ucode); - } else - cb->command = cpu_to_le16(cb_nop); + return; + } + +noloaducode: + cb->command = cpu_to_le16(cb_nop); } static void e100_setup_iaaddr(struct nic *nic, struct cb *cb, |
