2005-08-11[PATCH] S2io: Errors found during reviewraghavendra.koushik@neterion.com
Hi, This is a patch to incorporate comments from earlier 12 patches. It also fixes a few issues we found during this time. Following is a list of changes in this patch. Item 1 incorporates earlier comments. Issues addressed in items 2 to 4 were discovered recently. 1. wmb() call in s2io_xmit() replaced with mmiowb(). 2. The dtx_control register was earlier programmed incorrectly for Xframe II adapter. 3. As suggested by hardware team, after a reset, in case of Xframe II adapter, we clear certain spurious errors by clearing PCI-X ECC status register, "detected parity error" bit in PCI_STATUS register and PCI_STATUS bit in txpic_int register. 4. On IBM PPC platforms, we found that in the Rx buffer replenish function, two memory writes(one to the the descriptor length and another to the ownership) were getting reordered. This was causing the adapter to see the ownership transfered to it before the length was updated. One solution was to add a wmb() but since this would turnout expensive on some platforms if called for every descriptor, we set the ownership bit and other fields of '2' to 'N' Rx descriptors followed by a wmb() and then set the ownership of first descriptor ('1'). Here the value 'N' is configurable by making it a module loadable parameter (rxsync_frequency). (NOTE: This parameter is a power of 2). 5.

2005-08-11[PATCH] S2io: Miscellaneous fixesraghavendra.koushik@neterion.com
Hi, The last patch in this series fixes the following issues found during testing. 1. Ensure we don't pass zero sized buffers to the card(which can lockup) 2. Restore the PCI-X parameters(in case of Xframe I adapter) after a reset. 3. Make sure total size of all FIFOs does not exceed 8192.

2005-08-11[PATCH] S2io: Support for Xframe II NICraghavendra.koushik@neterion.com
Hi, This patch provides basic support for the Xframe II adapter. Includes the following changes: 1. New values to program XAUI interface. 2. Print the PCI/PCI-X mode(bus frequency, width). 3. Remove EOI from reset during intialization. 4. Enable all 8 PCCs if Xframe II adapter. 5. Programs the RLDRAM size depending on the device. (Note: RLDRAM size on XFARME-I is 64Mb whereas on XFRAME-II it's 32 Mb). 6. Enable extended(64-bit) statistics counters. 7. Program timer interrupt duration based on PCI/PCI-X clock speed. 8.

2005-08-11[PATCH] S2io: Performance improvementsraghavendra.koushik@neterion.com
Hi, This patch relates to mostly performance related changes. 1. Fixed incorrect computation of PANIC level in rx_buffer_level(). 2. Removed unnecessary PIOs(read/write of tx_traffic_int and rx_traffic_int) from interrupt handler and removed read of general_int_status register from xmit routine. 3. Enable two-buffer mode(for Rx path) automatically for SGI systems. This improves Rx performance dramatically on SGI systems.

Hi, Below patch addresses few h/w specific issues. 1. Check for additional ownership bit on Rx path before starting Rx processing. 2.

Tx continous interrupts is now a loadable parameter. 5. Reset the card if we get double-bit ECC errors. 6. A soft reset of XGXS being done to force a link state change has been eliminated. 7. After a reset, clear "parity error detected" bit, PCI-X ECC status register, and PCI_STATUS bit in tx_pic_int register. 8. The error in the disabling allmulticast implementation has been rectified. 9. Leave the PCI-X parameters MMRBC, OST etc. at their BIOS/system defaults.

It is removed because it creates a new binary sysfs-attribute, which doesn't have the limitiation of 4k. Expect for the Adaptec controllers, which has a limitation in the hardware this attribute doesn't make sense anywhere else. Until the sysfs API provides an attribute which doesn't buffer (like firmware) and let access to at least 64k blocks i provide a separate patch...

2005-08-08[SCSI] fix target scanning oops with fc transport classJames.Smart@Emulex.Com
We have some nasty issues with 2.6.12-rc6. Any request to scan on the lpfc or qla2xxx FC adapters will oops. What is happening is the system is defaulting to non-transport registered targets, which inherit the parent of the scan. On this second scan, performed by the attribute, the parent becomes the shost instead of the rport. The slave functions in the 2 FC adapters use starget_to_rport() routines, which incorrectly map the shost as an rport pointer. Additionally, this pointed out other weaknesses: - If the target structure is torn down outside of the transport, we have no method for it to be regenerated at the proper parent. - We have race conditions on the target being allocated by both the midlayer scan (parent=shost) and by the fc transport (parent=rport).

None of the entries in the global mode database is correct for this particular display, and it particularly has difficulty scaling up 640x480 (the default startup mode of nvidiafb) to 1920x1200 which causes the above described problem. 1, Add 1920x1200 to the global mode database. 2.
