2007-10-12[SCSI] qla2xxx: Add flash burst-read/write support.Andrew Vasquez
Newer ISPs support a mechanism to read and write flash-memory via the firmware LOAD/DUMP memory mailbox command routines. When supported, utilizing these mechanisms significantly reduces overall access times.

2007-01-31[SCSI] qla2xxx: Remove unnecessary spinlock primitive - mbx_reg_lock.Seokmann Ju

2006-10-03[SCSI] qla2xxx: Add iIDMA support.Andrew Vasquez
iIDMA (Intelligent Interleaved Direct Memory Access) allows for the HBA hardware to send FC frames at the rate at which they can be received by a target device. By taking advantage of the higher link rate, the HBA can maximize bandwidth utilization in a heterogeneous multi-speed SAN. Within a fabric topology, port speed detection is done via a Name Server command (GFPN_ID) followed by a Fabric Management command (GPSC). In an FCAL/N2N topology, port speed is based on the HBA link-rate. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-02-07[PATCH] qla2xxx: Pass input-buffer length to Get-ID-List mailbox command.andrew.vasquez@qlogic.com
Recent ISP24xx firmwares require that mailbox register 8 be set to the maximum number of bytes to transfer during DMA copying of the list. We safely set this value to zero (infinite), since the call is *only* made in FCAL topologies.

2006-01-14[SCSI] qla2xxx: Correct excessive delay during LOAD-RISC-RAM mailbox command.andrew.vasquez@qlogic.com
Problem report (against 2.4.x driver) from Jeff Layton <jlayton@redhat.com>: An OEM noticed that the U6 qla2200 driver would hang for around 2 minutes at boot time and then proceed normally. I found that the delay was occurring when loading the new firmware into the card, and was due to a schedule_timeout(10) added to the bottom of the polling loop. Some testing showed that the load ram operation on the card was very quick (on the order of a couple of jiffies), but the sleep in the polling loop was making each operation take around 25-30. The attached patch corrects this by making it skip sleeping during the load ram operation, since I believe we only do that when the module is plugged in. It also skips sleeping if the mbox_int flag got set during the current loop. This corrected the hang on my test setup, and OEM also confirmed that it corrected the problem for them.

2006-01-14[SCSI] qla2xxx: Use msleep() as delay during ISP polling.andrew.vasquez@qlogic.com
Mailbox commands are polled for completion during ISP initialization. During potentially 'long' mailbox commands (i.e. fabric login), we really don't want a busy-wait delay to potentially trigger a (benign) soft-lockup BUG().

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
