git tag 24.12 (would clobber existing tag)
by Paul Menzel 31 Mar '25

31 Mar '25

Dear coreboot folks, Just a quick question, if there the 24.12 tag was renewed back in December(?). $ LANG= git fetch --tags From ssh://review.coreboot.org:29418/coreboot ! [rejected] 24.12 -> 24.12 (would clobber existing tag) I don’t think, I manually added a tag, but I can’t say for certain, what I did several months ago. Kind regards, Paul [1]: https://doc.coreboot.org/releases/coreboot-24.12-relnotes.html

[coreboot - Support #588] (New) Deguard AssertionError using ./generatedelta.py on Dell Optiplex 5040 SFF (0T7D40) full rom dump
by Walter Sonius 31 Mar '25

Issue #588 has been reported by Walter Sonius. ---------------------------------------- Support #588: Deguard AssertionError using ./generatedelta.py on Dell Optiplex 5040 SFF (0T7D40) full rom dump https://ticket.coreboot.org/issues/588 * Author: Walter Sonius * Status: New * Priority: Normal * Category: userspace utilities * Target version: none * Start date: 2025-03-31 ---------------------------------------- Running the deguard `./generatedelta.py` on the flashrom dumped rom from a Dell Optiplex 5040 SFF (0T7D40 A00, Q170 chipset, ME 11.8.92.4222) 1.22 BIOS results in the following AssertionError: ``` ./generatedelta.py --input dell_optiplex_5040_sff_bios122.rom --output data/delta/dell5040sff Traceback (most recent call last): File "/home/neon/deguard/./generatedelta.py", line 55, in <module> mfs = MFS(me.entry_data("MFS")) ^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/neon/deguard/lib/mfs.py", line 43, in __init__ page = MFSPage(self.data[page * self.PAGE_SIZE:(page + 1) * self.PAGE_SIZE], page) # Load page ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/neon/deguard/lib/mfs.py", line 164, in __init__ self.chunks[chunk] = MFSChunk(data, chunk_id) ^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/neon/deguard/lib/mfs.py", line 273, in __init__ assert self.crc == MFS.Crc16(self.data + struct.pack("<H", self.chunk_id)) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ AssertionError ``` This "AssertionError" can be skipped by using "Filip Lewiński" [filipleple patch](https://codeberg.org/libreboot/deguard/issues/1) on `lib/mfs.py`: ``` - assert self.crc == MFS.Crc16(self.data + struct.pack("<H", self.chunk_id)) + print(f"Chunk ID: {self.chunk_id}, Data: {self.data.hex()[:100]}, Expected CRC: {self.crc}, Calculated CRC: {MFS.Crc16(self.data + struct.pack('<H', self.chunk_id))}") + # assert self.crc == MFS.Crc16(self.data + struct.pack("<H", self.chunk_id)) + if (self.crc != MFS.Crc16(self.data + struct.pack("<H", self.chunk_id))): + print ("Invalid CRC!!!\n") ``` It now lists the following 52 CRC invalid errors, but will create a delta folder structure like the example optiplex 3050 although it misses the `ptt` folder and some other files differ: ``` ./generatedelta.py --input dell_optiplex_5040_sff_bios122.rom

[coreboot - Feature #583] (New) Allow reconfiguring PCIe slots on Asus P8Z77-V
by Keith Hui 31 Mar '25

31 Mar '25

Issue #583 has been reported by Keith Hui. ---------------------------------------- Feature #583: Allow reconfiguring PCIe slots on Asus P8Z77-V https://ticket.coreboot.org/issues/583 * Author: Keith Hui * Status: New * Priority: Normal * Assignee: Keith Hui * Category: board support * Target version: none * Start date: 2024-11-30 * Related links: https://review.coreboot.org/c/coreboot/+/85413 * Affected hardware: mb/asus/p8z77-v ---------------------------------------- Vendor firmware allows configuring the PCIe slots in three different ways, by reallocating 4 of the PCIe lanes between PCIEX16_3, PCIEX1_1, PCIEX1_2, and the onboard ASM1061 serial ATA controller providing 2 additional SATA ports. The options are (devices not shown are disabled): * X4: PCIEX16_3 as x4 * X1: PCIEX16_3 as x1, PCIEX1_1, PCIEX1_2 * Auto: PCIEX16_3 as x1, PCIEX1_1, ASM1061 The technical details have been worked out and implemented as patch CB:85413. However, two issues remain: 1. Despite our best efforts, PCIEX1_2 still doesn't work. 2. Configuring PCIEX16_3 for 4x requires changing a PCH soft strap from firmware, and coreboot lacks infrastructure for doing so. It has been established that the descriptor itself, which contains the soft straps, needs to be reflashed to make this change. This issue tracks our progress implementing this feature. -- You have received this notification because you have either subscribed to it, or are involved in it.

Q on flashing IFD from within coreboot (IVB boards)
by Keith Hui 31 Mar '25

31 Mar '25

I have narrowed the IFD update logic to one UEFI module within vendor BIOS: PcieLaneDxe, and after running Ghidra on it, I have learned enough to start implementing it on coreboot. All is in pursuit of this: https://review.coreboot.org/c/coreboot/+/85413 It will also help with the recently upstream p8z77-v_le_plus, and Sabertooth Z77. Turns out vendor is also just reflashing the IFD after configuring some GPIOs on the board. They don't seem concerned about SPI controller freezing. My code is going to look like this: 8<------ static enum cb_err reprogram_ifd(u8 new_pciepcs1) { const unsigned int PCHSTRP9 = 0x124; u16 lvscc = RCBA16(0x38c4); const unsigned int lbes_map[] = { 256, 4 * KiB, 8 * KiB, 64 * KiB }; u8 * ifdbuf; u8 erase_opcode = (lvscc >> 8) & 0xff; unsigned int erase_size = lbes_map[lvscc & 0b11]; unsigned int i; ifdbuf = malloc(erase_size); /* Read */ memcpy(ifdbuf, (void *) 0xff800000, erase_size); /* Patch */ ifdbuf[PCHSTRP9] &= 0b11111100; ifdbuf[PCHSTRP9] |= (pciepcs1 & 0b11); /* Erase */ /* Write */ for (i = 0; i < erase_size; i+=64) { if (is_write_needed (ifdbuf+i, 64) { /* Write all 64 bytes if anything within isn't 0xff */ } } free(ifdbuf); return CB_SUCCESS; } 8<------ Q1: So far all boards in the Asus p8x7x-series family that need this use 8MiB SPI flash, so they're mapped to 0xff800000 when run as 32-bit. What is the right address to use when coreboot is compiled as 64-bit? Would I have to do "max int - 8 MiB"? Q2: I may have asked this before. Can I use SPI_FLASH Kconfig and the SPI flash driver? Can I use this without a FMD file? Or am I better off rolling my own again? Thanks Keith

These two HP Compaq devices are extremely similar, they use the same OEM proprietary BIOS upgrade files. Hardware wise the only 3 noticeable differences are that the "compaq_8300_elite_sff" comes with a Q77 chipset, SuperIO NPCD378 and J32 labeled 16x length "white" PCI-E slot versus a Q75 chipset, SuperIO NPCD379HAKFX with the J32 labeled slot populated with a limited physical 1x length "black" PCI-E slot on the "compaq_pro_6300_sff". Flashing from OEM proprietary BIOS 3.08revA enabling the FDO jumper on the motherboard as described for the compaq_8300_elite_sff works by booting with "iomem=relaxed" kernel parameter and specifying the specific 16MB chip 25Q128A: flashrom -p internal -w cbtest.rom -c "MT25QL128" Tested and Working: Poweron/Poweroff/Reboot CPU i3-3220 / e3-1225v2 RAM 1x 2x 4x populated slots total of 4GB/8GB/16GB/24GB (both 1.35v and 1.5v modules mixed with ECC) Serial port (including coreboot) PS2 keyboard (including SeaBIOS) PS2 mouse SATA 3 ports (blue/white/white) USB 2.0 4x front & 2x back ports USB 3.0 4x back ports Ethernet 1Gbit/100Mbit Display port works in SeaBIOS and OS VGA port only works in OS!

[coreboot - Bug #507] (Closed) Windows GPU driver fails to load on AMD based google/guybrush, google/skyrim boards
by Matt DeVillier 27 Mar '25

27 Mar '25

Issue #507 has been updated by Matt DeVillier. Status changed from New to Closed This isn't an issue when not using vboot/PSP verstage, so closing for now. ---------------------------------------- Bug #507: Windows GPU driver fails to load on AMD based google/guybrush, google/skyrim boards https://ticket.coreboot.org/issues/507#change-2049 * Author: Matt DeVillier * Status: Closed * Priority: Normal * Target version: none * Start date: 2023-08-30 * Affected versions: 4.15, 4.16, 4.17, 4.18, 4.19, 4.21, main * Affected hardware: google/guybrush, google/skyrim ---------------------------------------- The Windows GPU drivers on AMD Cezanne and Mendocino platform ChromeOS devices (google guybrush and skyrim boards respectively) fail to load due to the PSP boot mode being `Development` vs `Production.` On these platforms, the PSP only boots in `Production` mode when ChromeOS verified boot mode is active. Possible solutions include having the PSP boot in `Production` mode when vboot is not used at all, when CONFIG_CHROMEOS is not set, or (always) when PSP signed verstage is used. Any of these require changes to the PSP firmware from AMD. -- You have received this notification because you have either subscribed to it, or are involved in it.
