Similar to con_putc() in the previous patch: * make the pointer to charattr a pointer to u16, and * make x, y, and count unsigned as they are strictly non-negative. And again, document that hook. Signed-off-by:

Make parameters of consw::con_putc() saner: * x and y are unsigned now, as they cannot be negative, and * ca is made u16, as it is composed of two 8bit values (character and attribute). See the con_putcs() hook, u16/ushort is worked on there. And document the hook. Signed-off-by:

All these consw::con_putc() implementations do the same as consw::con_putcs() (only for one charattr) or even call consw::con_putcs() on their own. Drop them, as thanks to the new con_putc() helper in the previous patch, the console code performs this already -- exactly if consw::con_putc() is missing (NULL). Signed-off-by:

And let it call consw::con_putc() if it exists, otherwise consw::con_putcs(). This is similar to tty_put_char(). It supports dropping unneeded duplication of code like sticon_putc() is (see the next patch). Signed-off-by:

'count' in consw::con_clear() is guaranteed to be positive. csi_X() (the only caller) takes the minimum of the vc parameter (which is at least 1) and count of characters till the end of the line. The latter is computed as a subtraction of vc->vc_cols (count) and vc->state.x (offset). So for the worst case, full line, it is 1. Therefore, there is no point in checking zero or negative values (width is now unsigned anyway). Signed-off-by:

In consw::con_clear(): * Height is always 1, so drop it. * Offsets and width are always unsigned values, so re-type them as such. This needs a new __fbcon_clear() in the fbcon code to still handle height which might not be 1 when called internally. Note that tests for negative count/width are left in place -- they are taken care of in the next patches. And document the hook. Signed-off-by:

The 'init' parameter of consw::con_init() is true for the first call of the hook on a particular console. So make the parameter a bool. And document the hook. Signed-off-by:

The return value of con_debug_enter() and con_debug_leave() is ignored on many fronts. So just don't propagate errors (the current implementations return 0 anyway) and make the return type a void. Signed-off-by:

Remove unneeded 'extern' keyword from function prototypes in selection.h. This makes it more readable as no more wrapping is needed on many places. Signed-off-by:

The count to process is supposed to be between 1 and vc->vc_cols - vc->state.x (or rows and .y). clamp() can be used exactly for this, instead of ifs and min(). Signed-off-by:

It's only an aid to people reading the header and/or calling vc_is_sel(). vc is only tested there, so having it const makes sense. Signed-off-by:

It is pretty unfortunate to set vc_data::vc_resize_user in two callers of vc_do_resize(). vc_resize_user is immediately reset there (while remembering it). So instead of this back and forth, pass 'from_user' as a parameter. Notes on 'int user': * The name changes from 'user' to 'from_user' on some places to be consistent. * The type is bool now as 'int user' might evoke user's uid or whatever. Provided vc_resize() is called on many places and they need not to care about this parameter, its prototype is kept unchanged. Instead, it is now an inline calling a new __vc_resize() which implements the above. This patch makes the situation much more obvious. Signed-off-by:

Avoid costly user copies under the console lock. So push the lock down from tioclinux() to sel_loadlut() and set_vesa_blanking(). It is now obvious what is actually protected. Signed-off-by:

Pass proper types and proper pointers (the data with an offset) to the TIOCL_* handlers. So that they need not to cast or add anything to the passed pointer. This makes obvious what is passed/consumed. Signed-off-by:

At least since commits feebed65 ("tty: shutdown method") and bc1e99d9 ("TTY: vt, add ->install"), tty->driver_data in vc is expected to be set since tty_operations::install() till ::cleanup(). So the checks of !tty->driver_data (aka !vc) in: * vc_do_resize() by tty -> ioctl(TIOCSWINSZ) -> vt_resize() * do_con_write() by tty -> tty_operations::write()/::put_char() * con_flush_chars() by tty -> ::flush_chars() are all superfluous. And also, holding a console lock is not needed to fetch tty->driver_data. Note there is even a stale comment in con_flush_chars() about a race between that and con_close(). But con_close() does not set tty->driver_data to NULL for years already. Drop all these in a hope I am not terribly mistaken. Signed-off-by:

The if (c >= 20 && c <= 0x3f) test added in commit 7a99565f is wrong. 20 is DC4 in ascii and it makes no sense to consider that as the bottom limit. Instead, it should be 0x20 as in the other test in the commit above. This is supposed to NOT change anything as we handle interesting 20-0x20 asciis far before this if. So for sakeness, change to 0x20 (which is SPACE). Signed-off-by:

display_desc is a pointer to a RO string. Instead, switch display_desc to a static array as we are used to. It BTW saves unnecessary 8B on the stack. Signed-off-by:
