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.

[XS] Change in coreboot[main]: mb/google/fatcat: Disable EnableFastVmode on Panther Lake H SoC
by Jérémy Compostella (Code Review) May 1, 2025

Attention is currently required from: Avi Uday, Jayvik Desai, Kapil Porwal, Pranava Y N, Subrata Banik. Hello Avi Uday, Jayvik Desai, Kapil Porwal, Pranava Y N, Subrata Banik, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/coreboot/+/87505?usp=email to look at the new patch set (#4). Change subject: mb/google/fatcat: Disable EnableFastVmode on Panther Lake H SoC ...................................................................... mb/google/fatcat: Disable EnableFastVmode on Panther Lake H SoC This commit addresses a performance issue on the Panther Lake H SoC by disabling the EnableFastVmode setting in addition to the CepEnable setting. It was discovered that merely disabling CepEnable was insufficient, as the FSP continued to program Panther Lake U IccLimit on FastVMode capable boards, causing performance degradation under high-stress conditions. By also disabling EnableFastVmode, the I_TRIP value is prevented from being set lower than the device's actual capability. TEST=Verify that IccLimit is programmed with FSP default values.
