[PATCH 0/2] scsi: fixes and improvements to bus scan
by Paolo Bonzini 27 Sep '17

27 Sep '17

The first patch fixes a regression where many disks on a single SCSI target could prevent LUN0 from booting on another target. The second patch then exploits the new scanning algorithm to speed up the bus scan on virtio-scsi, which has a higher limit for the target than the other adaptors and therefore was slowed down the most. Paolo Bonzini (2): scsi: ensure LUN0 is added first virtio-scsi: speed up SCSI bus scan src/hw/blockcmd.c | 6 ++++-- src/hw/esp-scsi.c | 10 ++++++++-- … [View More]

[PATCH 0/3] SeaVGABIOS serial console test
by Kevin O'Connor 05 Sep '17

05 Sep '17

Hi Gerd, I was curious to see what the "sercon" stuff would look like in SeaVGABIOS instead of in SeaBIOS. So, I put together a quick prototype. The code is also at: https://github.com/KevinOConnor/seabios/tree/testing This is just a proof-of-concept thing - I didn't implement any of the useful features you have in your series. Specifically, it doesn't unclutter the serial output, doesn't implement cp437 translations, and doesn't handle multi-byte input. It does does have basic input, … [View More]

[PATCH] ahci: Disable Native Command Queueing
by Zeh, Werner 23 Jun '17

23 Jun '17

The AHCI driver currently sets the NCQ bit for every command that is issued to the SATA drive. This is not needed as there is always only one command active at a time and in turn can lead to a hanging AHCI controller (true for Marvel 88SE9170). The following patch disables the usage of NCQ completely. With this patch the Marvel AHCI controller works just fine without any issues.

Re: [SeaBIOS] Seabios can only detect one disk when two disks are attached to one scsi controller
by Gerd Hoffmann 16 Jun '17

16 Jun '17

Hi, > <address type='drive' controller='0' bus='0' target='0' unit='0'/> > <address type='drive' controller='0' bus='0' target='0' unit='1'/> Fixed in master branch (added lun support), no release yet with that. For released versions you can use "target='1' unit='0'" as address, so the disk is attached as separate target not as lun. cheers, Gerd

How to run AHCI option rom in Seabios?
by Аладышев Константин 15 Jun '17

15 Jun '17

I'm trying to enable SATA hotplug (in OS) feature on my board. And one of my attempts is to run AHCI option rom from original BIOS. I use coreboot/seabios bundle with seabios responsible for option ROM execution. And I stuck with a problem, that seabios doesn't want to run ROM on SATA controllers cause of pci->have_driver check: optionroms.c : // Find and deploy PCI roms. struct pci_device *pci; foreachpci(pci) { if (pci->class == … [View More]
