Fwd: Issues with ACPI _CRS and E820 memory map
by Tim Wawrzynczak 25 Aug '22

25 Aug '22

Hello fellow coreboot folks, I recently received this message from some associates in the Linux kernel community which describes a bug in coreboot firmware for many Intel boards. The gist of it related to inconsistencies between the hostbridge's _CRS method in ACPI and the E820 table (although technically generated by the payload, the e820 table is generally, AFAIK, converted straight from the LB_TAG_MEMORY entry in the coreboot table by most payloads). I have some thoughts on how to address this, but I would like to hear the community's thoughts first. Thanks, -Tim ---------- Forwarded message --------- From: Bjorn Helgaas <helgaas(a)kernel.org> Date: Thu, Aug 11, 2022 at 12:30 PM Subject: Issues with ACPI _CRS and E820 memory map To: <linux-pci(a)vger.kernel.org> Cc: Hans de Goede <hdegoede(a)redhat.com>, Myron Stowe <mstowe(a)redhat.com>, Kai-Heng Feng <kai.heng.feng(a)canonical.com>, Andy Shevchenko < andriy.shevchenko(a)linux.intel.com>, <linux-acpi(a)vger.kernel.org>, < linux-kernel(a)vger.kernel.org> This is a heads-up about what I think is a firmware defect in the way some platforms build _CRS methods. We've had a Linux workaround for several years, but the workaround breaks some new machines, so the workaround will be disabled for 2023 and newer machines. Machines that depend on the workaround include: - Dell Precision T3500 - Lenovo ThinkPad X1 Gen 2 - Asus C523NA (Coral) Chromebook - Likely any machine using coreboot firmware The current versions of the machines above work fine, but 2023 versions with similar firmware are likely to break unless the firmware changes. Please forward this to any firmware folks who may be able to help with this issue. Bjorn SUMMARY A Linux change will break future platforms that rely on the E820 memory map to exclude portions of the PCI host bridge windows reported by ACPI _CRS methods. Linux discovers PCI host bridge MMIO windows by evaluating the _CRS method of the ACPI PNP0A03 device that describes the host bridge. It uses these windows to assign address space to PCI BARs. In some cases these _CRS methods are incomplete or incorrect, and it's hard for an OS to work around this. Below are examples of typical problems with _CRS methods. PLATFORMS REPORT NON-WINDOW SPACE VIA _CRS Sometimes _CRS includes host bridge register space or space assigned to hidden PCI devices that are not enumerable by the OS. When an OS assigns this space to PCI devices, it may cause conflicts or devices may not work. This appears to be a firmware defect. Many platforms report this non-window space as "reserved" in the E820 memory map, and since 2010, Linux has worked around the _CRS defect by excluding these E820 "reserved" regions from the host bridge MMIO windows [4]. Example 1: _CRS includes space that's not usable for PCI devices [1]: E820: [mem 0xdceff000-0xdfa0ffff] reserved PNP0A08 _CRS: [mem 0xdfa00000-0xfebfffff] Note that [mem 0xdfa00000-0xdfa0ffff] is included in both the E820 entry and _CRS. If Linux assigns [mem 0xdfa00000-0xdfbfffff] to a PCI device, the system doesn't resume correctly from suspend. If Linux avoids the [mem 0xdfa00000-0xdfa0ffff] area and instead assigns [mem 0xdfb00000-0xdfcfffff], resume works correctly. Example 2: _CRS includes space assigned to a "hidden" PCI device [2, 5]: PCI: 00:0d.0 10 base d0000000 limit d0ffffff mem (fixed) # BIOS log E820: [mem 0xd0000000-0xd0ffffff] PNP0A08 _CRS: [mem 0x80000000-0xe0000000] The 00:0d.0 device is assigned the [mem 0xd0000000-0xd0ffffff] space, but the device is hidden so the OS cannot enumerate it, so the OS doesn't know what space the device consumes. PLATFORMS SUPPLY E820 ENTRIES COVERING ENTIRE _CRS WINDOWS Some recent platforms supply E820 "reserved" regions that cover entire PCI host bridge windows. If Linux excludes these E820 regions from the windows, it cannot assign space to PCI BARs, which means hot-added devices don't work. Example 3: E820 has a "reserved" region that completely covers the 32-bit MMIO window from _CRS [3]: E820: [mem 0x4bc50000-0xcfffffff] reserved PNP0A08 _CRS: [mem 0x65400000-0xbfffffff] Historically, Linux has avoided putting PCI devices in E820 reserved regions to avoid the problems in examples 1 and 2. Avoiding those regions in this case means Linux can't assign space for hot-added devices, so they don't work. LINUX PLANS As far as I know, the ACPI spec does not require an OS to exclude space from _CRS resources based on the E820 memory map, and these conflicting requirements make it impractical for Linux to do so. The "avoid E820 regions" workaround worked for several years, but it no longer works because of platforms that advertise E820 regions that cover *entire* _CRS windows. We plan to make Linux stop excluding E820 regions from _CRS resources for platforms with a BIOS date of 2023 or newer, so new platforms or new BIOS releases that rely on excluding E820 regions may break [6]. Linux is likely to be broken on future versions of these platforms unless the firmware updates _CRS methods. If these platforms do not update _CRS methods to be complete and accurate, Linux may not boot. The user's options are to: - Manually boot with a kernel command line option like "pci=use_e820". - Wait for an updated kernel with a platform-specific workaround. WHY DOESN'T THIS AFFECT MICROSOFT WINDOWS? Short answer: I suspect it *does*, but it's less likely to be a problem on Windows. As far as I know, Windows does not exclude MMIO space from _CRS based on the E820 memory map. But Windows allocates PCI BARs from the top down, while Linux allocates from the bottom up. Most of the issues happen with space at the bottom of the _CRS MMIO windows, so Linux is more likely to trip over them than Windows is.

Coffee Lake Refresh RVP11 + Integrated graphics initialisation + Uefipayload
by Moorthi M.s 25 Aug '22

25 Aug '22

Hi, I am developing coreboot along with Uefipayload for CFL H RVP11 CRB. I have added the required binary files (me, desc, ec and gbe) by extracting from the BIOS image. I have also extracted and added the vbt.bin from BIOS to coreboot. For graphics initialisation, i selected "Run a GOP driver" and for Framebuffer mode, i selected "Linear high resolution framebuffer". Compiled and loaded the coreboot image with above configuration. Coreboot booted and the debug prints are displayed in UART port, but nothing came in the graphics. The Display is connected to the DP port of the CRB. And i checked the debug prints, there it is mentioned as "GMA: Found valid VBT in CBFS" and in the next line "Graphics hand-off block not found". From the above prints i assume that the vbt.bin is proper but still the FSP is not returning the graphics HOB. I am using coreboot 4.17 for my development. Is there any other configurations need to be done with respect to integrated graphics? Regards, Moorthi S

Issue tracker version update / disabling of login methods
by Felix Singer 18 Aug '22

18 Aug '22

Hi all, the Redmine developers released version 5.0 some months ago and updating to this version will have some effects on us. So, I would like to open a thread to discuss these issues with you and how we deal with that situation. Currently, we are on the 4.2 branch and it still gets security and bug fixes, but I can't tell at which point they will stop supporting it. We enabled the login over OpenID, which is implemented natively and not integrated over a plugin. With version 5.0, support for that was removed. I assume this is due to that the implementation is based on an older OpenID standard and there are not many users of it anymore (TM). The newer standard seems to be called "OpenID Connect", but it's not supported by Redmine. Also, we are using a plugin which allows the login over a Google account. The compatibility of that plugin breaks with version 5.0. The problem is that we have users for both and with version 5.0 they won't be able to use these methods anymore. However, I have an idea for a solution. I took a look at the Redmine database and I played around with the Google login method. My tests showed that it creates a normal user account, as it is done with the registration, just with the little difference that no password is set disabling the login over password. These accounts also have an user name and an email address. As soon as I set a password, I was able to login using the user name. So, my idea is that we just go with these changes and affected users use the functionality to reset their password, which means they will have a "normal" user account then. In preparation to that version update, we should disable these login methods so that no new users will make use of them. Other ideas? What's your opinion? // Felix

Intel sandybridge northbridge with ibexpeak southbridge?
by Hal Martin 18 Aug '22

18 Aug '22

Hello, I have a platform (Advantech NAMB-3250MB, used in some Riverbed appliances) which uses Sandy/Ivy Bridge CPUs, but has a DH89xxCC southbridge which according to ifdtool is Ibex Peak. [3] The ME firmware version from the vendor firmware is 6.0.50.1244 which also corresponds to Ibex Peak (Series 5) and not Cougar Point (Series 6). [1] I did not know it was possible to pair a Series 5 chipset with Sandy/Ivy Bridge, since the DH89xxCC only supports DMI 1 (intel-communications-chipset-89xx-series-datasheet.pdf page 5) and Sandy/Ivy Bridge support DMI 2.0 [2] It would appear that using northbridge/intel/sandybridge with southbridge/intel/ibexpeak in coreboot is not supported: /opt/coreboot/util/crossgcc/xgcc/bin/i386-elf-ld.bfd: build/romstage/northbridge/intel/sandybridge/early_dmi.o: in function `early_init_dmi': /opt/coreboot/src/northbridge/intel/sandybridge/early_dmi.c:175: undefined reference to `early_pch_init_native_dmi_pre' /opt/coreboot/util/crossgcc/xgcc/bin/i386-elf-ld.bfd: /opt/coreboot/src/northbridge/intel/sandybridge/early_dmi.c:215: undefined reference to `early_pch_init_native_dmi_post' /opt/coreboot/util/crossgcc/xgcc/bin/i386-elf-ld.bfd: build/romstage/northbridge/intel/sandybridge/raminit.o: in function `init_dram_ddr3': /opt/coreboot/src/northbridge/intel/sandybridge/raminit.c:322: undefined reference to `early_pch_init_native' src/arch/x86/Makefile.inc:185: recipe for target 'build/cbfs/fallback/romstage.debug' failed make: *** [build/cbfs/fallback/romstage.debug] Error 1 There is no early_pch_init_native_* in src/southbridge/intel/ibexpeak Is it safe to assume that IronLake northbridge is not applicable to Sandy/Ivy Bridge CPUs? In which case, I guess the only way this platform could ever be supported is if the missing early_pch_init_native_* functions are implemented for IbexPeak?

RFC: Deprecating VBOOT_VBNV_CMOS
by Yu-Ping Wu 14 Aug '22

14 Aug '22

Hi, There's an ongoing effort to expand vboot nvdata (nvstorage) from 16 to 64 bytes [issue <https://issuetracker.google.com/issues/172342278>]. To reduce unnecessary complexity of our firmware code accessing nvdata, we'd like to drop 16-byte nvdata support from the firmware codebase (crossystem still needs to support both though). One obstacle is the CMOS nvdata backend (VBOOT_VBNV_CMOS). We're not sure if there would be enough CMOS space for all boards using that. In addition, because CMOS loses state when the battery is removed, newer boards usually select VBOOT_VBNV_CMOS_BACKUP_TO_FLASH to backup nvdata to flash. Considering that, this seems like a good opportunity to migrate CMOS to flash nvdata [issue <https://issuetracker.google.com/issues/235293589>]. One problem we faced is that many old platforms such as broadwell don't support writing to the flash in early stages (BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES). Therefore it looks like we'd need to drop vboot support on them (for example CB:65782 <https://review.coreboot.org/c/coreboot/+/65782>). An alternative would be to keep the CMOS backend around as "deprecated" and not allow 64-byte nvdata for it, but that would at best be a transitory solution for a couple of years, not forever. If there's any concern, please let me know. We have firmware branches for ChromeOS devices, so modifying ToT code wouldn't affect old devices in any way. However, I'm not sure how non-ChromeOS boards (such as mainboard/lenovo/haswell) would be affected by this. Please cc more people if needed. -- Yu-Ping Wu | Software Engineer | yupingso(a)google.com | +886 937 057 080
