2021-04-14kconfig: nconf: refactor attributes setup codeMasahiro Yamada
The current attributes setup code is strange; the array attribute[] is set to values outside the range of the attribute_t enum. At least, attributes_t attributes[ATTR_MAX+1] = {0}; ... should be int attribute[ATTR_MAX+1] = {0}; Also, there is no need to hard-code the color-pair numbers in attributes_t. The current code is messy. Rewrite it. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: nconf: remove unneeded default for menu promptMasahiro Yamada
The rootmenu always has a prompt even if the 'mainmenu' statement is missing in the top Kconfig file. conf_parse() calls menu_add_prompt(P_MENU, "Main menu", NULL) in this case. So, every 'menu' has a prompt. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: nconf: get rid of (void) casts from wattrset() callsMasahiro Yamada
This reverts commit 10175ba65fde ("nconfig: Silence unused return values from wattrset"). With this patch applied, recent GCC versions can cleanly build nconf without "value computed is not used" warnings. The wattrset() used to be implemented as a macro, like this: #define wattrset(win,at) \ (NCURSES_OK_ADDR(win) \ ? ((win)->_attrs = NCURSES_CAST(attr_t, at), \ OK) \ : ERR) The GCC bugzilla [1] reported a false-positive -Wunused-value warning in a similar test case. It was fixed by GCC 4.4.1. Let's revert that commit, and see if somebody will claim the issue. [1]: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=39889 Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: nconf: fix NORMAL attributesMasahiro Yamada
The lower 8-bit of attributes should be 0, but this code wrongly sets it to NORMAL (=1). The correct one is A_NORMAL. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: mconf,nconf: remove unneeded '\0' termination after snprintf()Masahiro Yamada
snprintf() always terminates the destination buffer with '\0' even if the buffer is not long enough. (In this case, the last element of the buffer becomes '\0'.) The explicit termination is unneeded. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: use /boot/config-* etc. as DEFCONFIG_LIST only for native buildMasahiro Yamada
When the .config file is missing, 'make config', 'make menuconfig', etc. uses a file listed in DEFCONFIG_LIST, if found, as base configuration. Ususally, /boot/config-$(uname -r) exists, and is used as default. However, when you are cross-compiling the kernel, it does not make sense to use /boot/config-* on the build host. It should default to arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG). UML previously did not use DEFCONFIG_LIST at all, but it should be able to use arch/um/configs/$(KBUILD_DEFCONFIG) as a base config file. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: change sym_change_count to a boolean flagMasahiro Yamada
sym_change_count has no good reason to be 'int' type. sym_set_change_count() compares the old and new values after casting both of them to (bool). I do not see any practical diffrence between sym_set_change_count(1) and sym_add_change_count(1). Use the boolean flag, conf_changed. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
2021-04-14kconfig: nconf: fix core dump when searching in empty menuMasahiro Yamada
The following code in get_mext_match(): index = (index + items_num) % items_num; ... makes the program crash when items_num is zero (that is, the menu is empty). A menu can be empty when all the options in it are hidden by unmet 'depends on'. For example, menu "This menu will be empty" config FOO bool "foo" depends on BROKEN endmenu If you visit this menu and press a '/' key and then another key, nconf crashes with: Floating point exception (core dumped) When the number of items is zero, it does not make sense to search in the menu. In this case, current_item() returns NULL, and item_index() ERR, but get_mext_match() does not check it. Let's make get_mext_match() just return if the menu is empty. While I am here, change items_num from 'int' to 'unsigned int' because it should never become negative. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2021-04-14kconfig: do not use allnoconfig_y optionMasahiro Yamada
allnoconfig_y is an ugly hack that sets a symbol to 'y' by allnoconfig. allnoconfig does not mean a minimal set of CONFIG options because a bunch of prompts are hidden by 'if EMBEDDED' or 'if EXPERT', but I do not like to hack Kconfig this way. Use the pre-existing feature, KCONFIG_ALLCONFIG, to provide a one liner config fragment. CONFIG_EMBEDDED=y is still forced when allnoconfig is invoked as a part of tinyconfig. No change in the .config file produced by 'make tinyconfig'. The output of 'make allnoconfig' will be changed; we will get CONFIG_EMBEDDED=n because allnoconfig literally sets all symbols to n.

2021-04-14kconfig: change defconfig_list option to environment variableMasahiro Yamada
"defconfig_list" is a weird option that defines a static symbol that declares the list of base config files in case the .config does not exist yet. This is quite different from other normal symbols; we just abused the "string" type and the "default" properties to list out the input files. They must be fixed values since these are searched for and loaded in the parse stage. It is an ugly hack, and should not exist in the first place. Providing this feature as an environment variable is a saner approach. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2021-04-14x86/setup: Move trim_snb_memory() later in setup_arch() to fix boot hangsMike Rapoport
Commit a799c2bd29d1 ("x86/setup: Consolidate early memory reservations") moved reservation of the memory inaccessible by Sandy Bride integrated graphics very early, and, as a result, on systems with such devices the first 1M was reserved by trim_snb_memory() which prevented the allocation of the real mode trampoline and made the boot hang very early. Since the purpose of trim_snb_memory() is to prevent problematic pages ever reaching the graphics device, it is safe to reserve these pages after memblock allocations are possible. Move trim_snb_memory() later in boot so that it will be called after reserve_real_mode() and make comments describing trim_snb_memory() operation more elaborate.

2021-04-13mailbox: sprd: Add supplementary inbox supportOrson Zhai
Some sensors connected to Unisoc mailbox will send data very frequently. This makes channel 0 very busy and the messages from other remote cores not able to be handled as soon as possible. It's a trick (un-documented) from Unisoc ASIC designers to resolve this special requirement that an inbox assigned to one of the remote cores before was modified to be exposed to host cpu core. Then from host side, a supplementary inbox is added for transferring mass but not emergency messages from the remote cores, such as step counting sensor, with an independent FIFO and interrupt which is as same as channel 0. Meanwihle, inbox part of this channel is still kept for original remote core to use.
