Hello, Peter. |

|

I have another version of the patch which makes GPM usable on scrolled |
| 4 |
consoles. I'd like to think that it's now final. |

OK, I'm enclosing a patch for each version, 5.15.x and 6.1.y. I'm not |
| 22 |
aware of any outstanding bugs in these patches. In particular, the |
| 23 |
following have been fixed since the previous version: |
| 24 |
(i) The synchronisation between the "mouse" character buffer and the |
| 25 |
contents of the screen is now 100%. In particular, when changing |
| 26 |
fonts (e.g. at bootup), and when the Tux logos get removed from the |
| 27 |
screen, things continue working. |
| 28 |
(ii) CONFIG_LOGO (i.e. the Tuxes on bootup) can now be freely configured |
| 29 |
without losing functionality. |
| 30 |
|
| 31 |
Just a quick reminder of how to use these files for anybody else who |
| 32 |
might be interested: |
| 33 |
(i) cd /usr/src/linux-5.15.88-gentoo, or similar. (Or |
| 34 |
...-6.1.x-gentoo). |
| 35 |
(ii) patch -p1 < 5.15.80-GPM.20230203.diff (or the other one). |
| 36 |
(iii) Configure the kernel as normal. Additionally, under Device |
| 37 |
drivers/Graphic Support/Console display driver support, enable |
| 38 |
CONFIG_FRAMEBUFFER_CONSOLE_SOFT_SCROLLBACK, set the buffer size to |
| 39 |
taste (it's default is 128 kB) and accept the default enablement of |
| 40 |
CONFIG_FRAMEBUFFER_CONSOLE_SOFT_SCROLLBACK_GPM. |
| 41 |
(iv) Build the kernel and install it into your boot manager. |
| 42 |
(v) Reboot and enjoy! You can now use GPM in scrolled consoles. |
