* acpi/acpigen: rework acpigen_pop_len for different size PkgLengthFelix Held2023-11-151-6/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously acpigen_pop_len always wrote a 3 byte PkgLength to the 3 bytes reserved by acpigen_write_len_f. After this patch acpigen_pop_len encodes PkgLength in 1-3 bytes depending on the PkgLength. When less than the 3 bytes that were previously reserved in the corresponding acpigen_write_len_f call are needed for PkgLength, the payload data will be moved back by the number of reserved bytes that aren't needed for the PkgLength. This fixes the problem that the Windows AML parser doesn't like a 3 byte PkgLength being used for the size of the buffer containing UTF-16 strings when the length could be encoded in a single PkgLength byte. In that case, Windows previously ignored the whole SSDT containing this larger than necessary PkgLength encoding. It should however be noted that the ACPI 6.4 spec doesn't specify if it's required to always use the most compact possible encoding of the PkgLength or not. Since iasl generates the shortest possible PkgLength encoding, it's also a good idea to make coreboot's acpigen do the same although it's not required by the specification. With this patch applied, Windows still boots on Mandolin and the time it takes to write the tables doesn't change. To measure the times, the log level in bs_sample_time was increased to BIOS_CRIT and the console log level was increased to BIOS_CRIT too to only get those times as output.

* acpi/acpigen: generate DWord IO resource in acpigen_resource_producer_ioFelix Held2023-06-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | When an IO resource producer is generated that covers the whole IO space from 0 to 0xffff, the length field in the word resource ACPI type would overflow and be truncated which results in Linux not finding any usable IO space to use for the PCI IO BARs. Instead generate a double word IO resource producer to have all cases supported. Beware that covering all IO ports with the IO resource producer while covering the PCI config IO ports with a resource consumer in the same PCI root device will make Linux a bit unhappy and it will complain due to the overlap, but still end up doing the right thing: acpi PNP0A08:00: host bridge window expanded to [io 0x0000-0xffff]; [io 0x0000-0xffff window] ignored The SoC code should make sure to carve out the PCI config IO ports from the IO resource producer.

| | | | | | | | | | | | | | | | | | | | | Since it's not obvious, add comments to acpigen_resource_word, acpigen_resource_dword and acpigen_resource_qword to clarify out what the magic number in byte 0 means. The most significant bit of byte 0 indicates if it is a small or large resource data type. In the case of the MSB being 0, it's a small resource data type (aka type 0), and the other bits encode bit the type and size of the item; if the MSB is 1, it's a large resource data type (aka type 1), and the other bits just encode the type and there are two separate bytes to encode the size. Beware that the large resource's data type values in the ACPI specification don't include the MSB that's set, but only the 7 lower bits.

As a replacement, DEVICE_OP with the special HID ACPI0007 should be used instead. This special HID was introduced in version 3 of the ACPI spec. To have a function to generate this, acpigen_write_processor_device is introduced. The CPU index is used as UID which can be assumed to be unique.

* acpi/acpigen: factor out acpigen_write_processor_namestringFelix Held2023-01-281-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | This functionality is used in multiple places, so factor it out into a function. Compared to acpigen_write_processor_cnot, the buffer size is decreased from 40 to 16 bytes, but the format string specified by CONFIG_ACPI_CPU_STRING results in 9 chars and a NULL byte which will fit into the buffer without any issue. I've seen the CPU devices being put into another scope within \_SB, but even in that case that would be 14 chars and a NULL byte whist still fits into the 16 byte buffer. For acpigen_write_processor and acpigen_write_processor_package this doesn't change any edge case behavior. In the unrealistic case of the format string resulting in a longer CPU device string, this would have been a problem before this patch too. Also drop the curly braces of the for loop in acpigen_write_processor_package. This makes the code a bit harder to read and isn't a very good idea, but with the curly braces in place, the linter breaks the build :( Signed-off-by: Felix Held <felix-coreboot@felixheld.de> Change-Id: I5d8291a2aaae2011cb185d72c7f7864b6e2220ec Reviewed-on: https://review.coreboot.org/c/coreboot/+/72452 Reviewed-by: Fred Reitberger <reitbergerfred@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Matt DeVillier <matt.devillier@amd.corp-partner.google.com> Reviewed-by: Elyes Haouas <ehaouas@noos.fr>

| | | | | | | | | | | | | | | | | | | | | | | | | Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it).

This patch was created by running find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';' and doing some cursory review/cleanup on the result.
