2023-04-28vga: Change the arguments of vga_write_text to support extended ASCIIHsuan Ting Chen
VGA defined the extended ASCII set based on CP437, but the function vga_write_text() accepts a signed char array. This will cause unnecessary confusion that if we want to print u with umlaut (code=129 in CP437), we need to explicitly cast it to -127 in signed char. Since we still want to leverage the built-in string utilities which only accepts const char*, we still need to cast it to signed char while processing, and cast it back to unsigned once we write into the frame buffer.

2023-04-26soc/intel: Introduce ioapic_get_sci_pin()Kyösti Mälkki
According to ACPI Release 6.5 systems supporting PIC (i8259) interrupt mechanism need to report IRQ vector for the SCI_INT field. In PIC mode only IRQ0..15 are allowed hardware vectors. This change should cover section 5.2.9 to not pass SCI_INT larger than IRQ15. Section 5.2.15.5 needs follow-up work. Care should be taken that ioapic_get_sci_pin() is called after platform code has potentially changed the routing from the default.

When system starts Google Meet video call, it uses the hardware accelerated encoder as expected. But, as soon as another system connects to the call, an immediate fallback is observed from hardware to software encoder. Due to this, Google Meet resolution dropped from 720p to 180p. This issue is observed on Alder Lake-N SoC based fanless platforms. This same issue was not seen on fan based systems. With the fix in dptf driver where fan configures appropriate setting for only fan participant, not for other device participants, able to see consistent 720p resolution.

When cbmem is initialized in romstage and postcar placed in the stage cache + cbmem where it is run, the assumption is made that these are all in UC memory such that calling INVD in postcar is OK. For performance reasons (e.g. postcar decompression) it is desirable to cache cbmem and the stage cache during romstage. Another reason is that AGESA sets up MTRR during romstage to cache all dram, which is currently worked around by using additional MTRR's to make that UC. TESTED on asus/p5ql-em, up/squared on both regular and S3 resume bootpath. Sometimes there are minimal performance improvements when cbmem is cached (few ms).

2023-03-03lib: set up specific purpose memory as LB_MEM_SOFT_RESERVEDJonathan Zhang
CXL (Compute Express Link) [1] is a cache-coherent interconnect standard for processors, memory expansion and accelerators. CXL memory is provided through CXL device which is connected through CXL/PCIe link, while regular system memory is provided through DIMMs plugged into DIMM slots which are connected to memory controllers of processor. With CXL memory, the server's memory capacity is increased. CXL memory is in its own NUMA domain, with longer latency and added bandwidth, comparing to regular system memory. Host firmware may present CXL memory as specific purpose memory. Linux kernel dax driver provides direct access to such differentiated memory. In particular, hmem dax driver provides direct access to specific purpose memory. Specific purpose memory needs to be represented in e820 table as soft reserved, as described in [2]. Add IORESOURCE_SOFT_RESERVE resource property to indicate (memory) resource that needs to be soft reserved. Add soft_reserved_ram_resource macro to allow soc/mb code to add memory resource as soft reserved.

2023-02-15cpu/x86/smm: Enable setting SMM console log level from mainboardJohnny Lin
Add a Kconfig RUNTIME_CONFIGURABLE_SMM_LOGLEVEL that enables mainboard to override mainboard_set_smm_log_level for SMM log level. This can let SMM have different log level than other stages for more flexibility. Another reason is that getting certain data that requires searching from flash VPD or CMOS is not very ideal to be done in SMM, so in this change the value can be passed via the member variable in struct smm_runtime and be referenced directly in SMM. One example is that mainboard can get the desired SMM log level from VPD/CMOS, and pass SMM console log level via the variable and in SMM it can be referenced in get_console_loglevel() override function directly. Tested=On OCP Delta Lake, verified SMM log level can be overridden.

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>

2023-01-02drivers/pc80/vga: Add API to write multi-line video messageSubrata Banik
This patch provides an API to allow users to output multi-line messages using VGA framebuffer. The current limitation with multiline message is that, vga_line_write() function is unable to understand newline character hence, eventually output multiple lines separated with a newline character with a single line statement. This patch ensures to parse the entire string and split it into multiple lines based on the newline character and print each line separately to the VFG framebuffer. User can choose to align the output video message as per given choice between left/center/right of the screen (i.e. enum VGA_TEXT_ALIGNMENT ). Additionally, added macros to define the horizontal screen alignment as well. Ideally if user would like to print the video message at the middle of the screen then the vertical alignment would be `VGA_TEXT_CENTER` and horizontal alignment would be `VGA_TEXT_HORIZONTAL_MIDDLE`. TEST=Able to build and boot Google/Taeko. While output a video message such as : "Your device is finishing an update. This may take 1-2 minutes.\nPlease do not turn off your device." Without this patch: Your device is finishing an update. This may take 1-2 minutes. nPlease do not turn off your device. With this patch: (in Left Alignment): Your device is finishing an update. This may take 1-2 minutes. Please do not turn off your device. (in Right Alignment): Your device is finishing an update. This may take 1-2 minutes. Please do not turn off your device. (in Center Alignment): Your device is finishing an update. This may take 1-2 minutes. Please do not turn off your device.

There are four requirements for the SMI to hit a printk() this commit now removes. Build must have DEBUG_SMI=y, otherwise any printk() is a no-op inside SMM. ASL must have a TRAP() with argument 0x99 or 0x32 for SMIF value. Platform needs to have IO Trap #3 enabled at IO 0x800. The SMI monitor must call io_trap_handler for IO Trap #3. At the moment, only getac/p470 would meet the above criteria with TRAP(0x32) in its DSDT _INI method. The ASL ignores any return value of TRAP() calls made. A mainboard IO trap handler should have precedence over a southbridge IO trap handler. At the moment we seem to have no cases of the latter to support, so remove the latter.

2022-11-24src/device + util/sconfig: Introduce new device 'mdio'Mario Scheithauer
This patch extends the available device paths with a new device 'mdio'. MDIO is the 'Management Data Input/Output' called interface which is used to access an Ethernet PHY behind a MAC to change settings. The real payload data path is not handled by this interface. To address the PHY correctly on the MDIO bus, there is a 5 bit address needed, which often can be configured via pins on the mainboard. Therefore, the new introduced device has an 'addr' field to define its address. If one wants to use a MDIO device in devicetree, the syntax is straight forward (example): device mdio 0x2 on end As the MDIO interface is driven by the MAC, most likely this MDIO device will be hooked in as a child device of the (PCI attached) MAC device. With the new introduced ops_mdio a new interface is added to provide an API for read and write access over MDIO.

This moves a lot of post code values, but unifies them between platforms, so that the same value means the same thing as much as possible. The P4-netburst code was the most extensive and most different, so that dictated the majority of the values. Three were two values there that didn't match the other files, so those two values, 0x22 & 0x29 have duplicate entries in the table. The rest of the entries are similar between platforms, though the values for many of them were moved to match the P4-netburst values. POST_BOOTBLOCK and POST_POSTCAR values are intended to eventually become global, while POST_SOC would be specific to the Intel platforms.
