Change in coreboot[master]: sb/intel/i82371eb: Implement SMBus Control Method Interface support
by Keith Hui (Code Review) 03 Jan '23

Keith Hui has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/41735 ) Change subject: sb/intel/i82371eb: Implement SMBus Control Method Interface support ...................................................................... sb/intel/i82371eb: Implement SMBus Control Method Interface support Upcoming ACPI support for asus/p3b-f mainboard contains ASL code to manipulate its AS99127F chip over SMBus before and after suspend, to blink front panel lights, turn off fans, among other things. This code caused an ACPI/PCI resource conflict that disabled access to the entire SMBus, rendering its hardware monitor inoperative, and all resolution attempts so far have not worked. This is an attempt to expand the ASL SMBus routines into a complete SMBus Control Method Interface (SCMI), that Linux kernel can use via the i2c-scmi driver, sidestepping this conflict. Because SCMI methods begin with an underscore, which iasl considers "unknown reserved name", on which our build process errors out, it must also be told to ignore this particular warning, at least for asus/p3b-f.

However, not everything is used in both ramstage and smm, so there's a lot of `__unused` tags. So, reorder the functions so that they build only for stages needing them. Tested with BUILD_TIMELESS=1, Asrock B85M Pro4 remains identical.

Change in ...coreboot[master]: SeaBIOS - unofficial patches: advanced_bootmenu and multiple_floppies
by mikeb mikeb (Code Review) 30 Nov '22

30 Nov '22

Hello Mike Banon, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/32351 to review the following change. Change subject: SeaBIOS - unofficial patches: advanced_bootmenu and multiple_floppies ...................................................................... SeaBIOS - unofficial patches: advanced_bootmenu and multiple_floppies If you'd like to add the useful floppies to your coreboot (read about them at http://dangerousprototypes.com/docs/Lenovo_G505S_hacking#Useful_floppies ), or to use your USB numpad for choosing a SeaBIOS boot entry, then this change is for you! It contains two valuable patches together with a Makefile mod needed to automatically apply these patches to a cloned SeaBIOS before its' compilation. advanced_bootmenu: up to 35 entries (2 pages if >18), numpad support (console) https://mail.coreboot.org/hyperkitty/list/seabios@seabios.org/thread/CKWLNT… [PATCH v2] ramdisk: search for all available floppy images instead of one https://mail.coreboot.org/pipermail/seabios/2018-December/012670.html Patch descriptions are available at these links, and just in case here's a copy: advanced_bootmenu: up to 35 entries (2 pages if >18), numpad support (console) Add support for up to 35 boot menu entries (2 pages if >18). To solve the ">10" problem currently experienced by SeaBIOS users (there are no 11, 12, etc. keys on a keyboard - so impossible to choose the last menu entries if you got >10 entries because of multiple hard drives / secondary payloads / floppies) - the boot menu has been extended to the letter keys. NOTE: TPM menu has been moved from T to M letter: it is at the end of keyboard's 3rd row of letters and "Trusted" is adjective while "Module" is a noun; alternatively could press '-'. Also, add support for a numpad. Small USB numpad could be really convenient for choosing the boot entries at coreboot boards used as (maybe headless) servers. '/' char on numpad could be used to open the boot menu or to exit it. If there are >10 boot menu entries - the numpad console interface will be enabled: press one or two digit keys and then ENTER to confirm your choice, or remove a digit by pressing the '.Del' key. Also you could call TPM with '-' key at any moment, or boot with a single key press of your fullsize keyboard. [PATCH v2] ramdisk: search for all available floppy images instead of one All the floppy images available at CBFS will be found and listed in a boot menu, instead of the first found. Could be highly valuable if you are participating in a hobby OS development - would like to test multiple versions of your floppy at the same coreboot image, to reduce the amount of re-flashes and accelerate the development at bare metal - or simply you would like to access multiple floppies as a coreboot user. For example: KolibriOS (nice assembly OS with GUI and apps), FreeDOS, MichalOS, Snowdrop and memtest (coreboot's memtest version is buggy, e.g. external USB keyboard isn't working at some laptops; floppy is much better) Signed-off-by: Mike Banon <mikebdp2(a)gmail.com> Change-Id: Idf4efba31091a8678b51c2f6541d440c5cc6d37d --- M payloads/external/SeaBIOS/Makefile A payloads/external/SeaBIOS/advanced_bootmenu.patch A payloads/external/SeaBIOS/multiple_floppies.patch 3 files changed, 551 insertions(+), 1 deletion(-) git pull ssh://review.coreboot.org:29418/coreboot refs/changes/51/32351/1 diff --git a/payloads/external/SeaBIOS/Makefile b/payloads/external/SeaBIOS/Makefile index e505c8c..ae58c8c 100644 --- a/payloads/external/SeaBIOS/Makefile +++ b/payloads/external/SeaBIOS/Makefile @@ -76,7 +76,18 @@ # echo "# CONFIG_SMBIOS is not set" >> seabios/.config $(MAKE) -C seabios olddefconfig OUT=out/ -build: config +patch: + if [ -d seabios ]; then \ + cd seabios; \ + if [ ! -f .patched ]; then \ + echo " PATCH SeaBIOS $(TAG-y)"; \ + patch -p1 < ./../advanced_bootmenu.patch; \ + patch -p1 < ./../multiple_floppies.patch; \ + touch .patched; \ + fi; \ + fi + +build: config patch echo " MAKE SeaBIOS $(TAG-y)" $(MAKE) -C seabios OUT=out/ diff --git a/payloads/external/SeaBIOS/advanced_bootmenu.patch b/payloads/external/SeaBIOS/advanced_bootmenu.patch new file mode 100644 index 0000000..c914588 --- /dev/null +++ b/payloads/external/SeaBIOS/advanced_bootmenu.patch @@ -0,0 +1,332 @@ +diff --git a/src/boot.c b/src/boot.c +index 9f82f3c..f94dd27 100644 +--- a/src/boot.c ++++ b/src/boot.c +@@ -463,6 +463,7 @@ get_keystroke(int msec) + * Boot menu and BCV execution + ****************************************************************/ + ++#define BOOTMENU_PAGE_SIZE 18 + #define DEFAULT_BOOTMENU_WAIT 2500 + + // Show IPL option menu. +@@ -478,59 +479,282 @@ interactive_bootmenu(void) + ; + + char *bootmsg = romfile_loadfile("etc/boot-menu-message", NULL); +- int menukey = romfile_loadint("etc/boot-menu-key", 1); +- printf("%s", bootmsg ?: "\nPress ESC for boot menu.\n\n"); ++ int menukey = romfile_loadint("etc/boot-menu-key", 1); // custom menukey ++ printf("%s", bootmsg ?: "\nPress ESC or \\ / slash for boot menu.\n\n"); + free(bootmsg); + + u32 menutime = romfile_loadint("etc/boot-menu-wait", DEFAULT_BOOTMENU_WAIT); + enable_bootsplash(); + int scan_code = get_keystroke(menutime); + disable_bootsplash(); +- if (scan_code != menukey) ++ if (scan_code != menukey && // custom menukey ++ scan_code != 1 && // ESC ++ scan_code != 43 && // '\' char on keyboard ++ scan_code != 53 && // '/' char on keyboard ++ scan_code != 98) { // '/' char on numpad ++ if (scan_code == -1) ++ printf("No key pressed.\n"); ++ else ++ printf("Not a menukey pressed.\n"); + return; ++ } + + while (get_keystroke(0) >= 0) + ; + +- printf("Select boot device:\n\n"); + wait_threads(); + +- // Show menu items ++ char keyboard_keys[35] = {'1','2','3','4','5','6','7','8','9','0', ++ 'q','w','e','r','t','y','u','i','o','p', ++ 'a','s','d','f','g','h','j','k','l', ++ 'z','x','c','v','b','n'}; /* m = TPM */ ++ int numpad_scancodes[10] = { 82, 79, 80, 81, 75, 76, 77, 71, 72, 73 }; ++ int numpi = 0; // Key index: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. ++ int digits = 0; // Numerical length of a current choice number. ++ int decode = 0; // Decode the current choice number into a letter? ++ int entry_id = 0; ++ char desc[77]; ++ ++ printf("Select boot device"); ++ ++ // Show menu items after counting them and determining a number of pages. ++ // Only 35 boot menu items (36 if to count a TPM) are supported currently. ++ + int maxmenu = 0; + struct bootentry_s *pos; +- hlist_for_each_entry(pos, &BootList, node) { +- char desc[77]; ++ hlist_for_each_entry(pos, &BootList, node) + maxmenu++; +- printf("%d. %s\n", maxmenu ++ ++ if (maxmenu > 10) { ++ if (maxmenu > 35) ++ maxmenu = 35; ++ if (maxmenu > BOOTMENU_PAGE_SIZE) ++ printf(" - page 1 :"); ++ else ++ printf(": "); ++ printf(" // press ENTER after your numpad input"); ++ if (maxmenu > BOOTMENU_PAGE_SIZE) ++ printf(" - if any -\n " ++ " // - or to switch between the pages...\n"); ++ else ++ printf(" (if any)\n\n"); ++ } else { ++ printf(":\n\n"); ++ } ++ ++ hlist_for_each_entry(pos, &BootList, node) { ++ if (entry_id == BOOTMENU_PAGE_SIZE) // Show only the first page. ++ break; ++ printf("%c. %s\n", keyboard_keys[entry_id] + , strtcpy(desc, pos->description, ARRAY_SIZE(desc))); ++ entry_id++; + } ++ int tpm_cshm = 0; + if (tpm_can_show_menu()) { +- printf("\nt.
