[PATCH v3 0/5] Make seabios linkable with lld
by Fangrui Song Aug. 12, 2021

Aug. 12, 2021

This patch series make seabios linkable with lld. This is beneficial for FreeBSD ports as well https://svnweb.freebsd.org/ports/head/misc/seabios/Makefile as they can drop an LLD_UNSAFE As a maintainer of lld ELF, I have triaged numerous pieces of software. seabios is the only one making use of This drops the only instance https://sourceware.org/bugzilla/show_bug.cgi?id=12726 1, 2, 3 and 4 are really independent and can be applied in arbitrary order. 5 depends on 4. I originally combined 4 and 5 and that was why I don't think a patch series made sense. Fangrui Song (5): romlayout.S: Add missing SHF_ALLOC flag to .fixedaddr.\addr Make rom16.o linkable with lld Makefile: Change ET_EXEC to ET_REL so that lld can link bios.bin.elf romlayout32flag.lds: Use `. +=` instead of `. =` test-build.sh: Delete unneeded LD capability test Makefile | 4 ++++ scripts/layoutrom.py | 13 ++++++++++--- scripts/test-build.sh | 42 +----------------------------------------- src/romlayout.S | 2 +- 4 files changed, 16 insertions(+), 45 deletions(-) -- 2.26.0.292.g33ef6b2f38-goog

[PATCH] AHCI: The attached ATA device cannot be detected when binding AHCI controller to Virtual Machine
by RunaGuo-oc＠zhaoxin.com March 29, 2021

March 29, 2021

When binding AHCI controller to virtual machine, the attached ATA device cannot be recognized for the following reason: The first Identify PACKET CMD will be failed without dobut which will lead PORT_IRQ_TF_ERR be set in PxIS due to ERR bit set to 1 in D2H Register FIS(PxTFD.STS.ERR=1). In this case, the first CMD will be timeout for seabios only polling PORT_IRQ_D2H_REG_FIS & PORT_IRQ_PIOS_FIS before triggering error handling which leads AHCI controller is an error state, then the second IDENTIFY CMD cannot be issued by AHCI controller, no ATA device will be detected. In AHCI spec HBA Port State Machine section(5.3.8.1 and 5.3.16.5), we can see this sequence: RegFIS:Entry --> ERR:FatalTaskfile (PxTFD.STS.ERR=1) --> ERR:WaitForClear, no entry for PORT_IRQ_D2H_REG_FIS/PORT_IRQ_PIOS_FIS to be set at this time. May be we can also add PORT_IRQ_TF_ERR bit check when polling command completion status? fail log: 02.386: |bffa6000| AHCI/1: link up 02.387: |bffa6000| AHCI/1: send cmd ... 02.387: |bffa7000| phys_free bffa9c00 (detail=0xbffaa320) 02.396: |bffa7000| phys_free bffaa200 (detail=0xbffaa1d0) 02.396: |bffa7000| phys_free bffaa000 (detail=0xbffaa1a0) 02.396: |bffa7000| phys_free bffaa380 (detail=0xbffaa350) 02.400: \bffa7000/ End thread 02.401: phys_free bffa7000 (detail=0xbffaa170) 34.391: |bffa6000| WARNING - Timeout at ahci_command:153! 34.392: |bffa6000| AHCI/1: send cmd ... 66.397: |bffa6000| WARNING - Timeout at ahci_command:153!

[SeaBIOS][PATCH] USB:Fix xHCI initail fail by using longer reset and CNR clear timeout value
by weitaowang-oc＠zhaoxin.com Sept. 30, 2020

Sept. 30, 2020

Some xHCI controller's reset time than 100ms,such as 120ms. On the on hand, xHCI spec has not specified a timeout value. Maybe setting xHCI HCRST and CNR bit clear timeout value larger is a nice thing.As a compromise between compatibility and latency,we can take 1000ms as a timeout value.
