Hello! Virtual Framebuffer for monochrome embedded LCD with Epson controller SED1335 (S1D13305) are available. ftp://ssv-embedded.de/ssv/products/trm916/sample/x86/linux/fbdev/ Routines using monochrome RAM of CPU or Pseudocolor RAM and update this to LCD hardware in timer interval. This is a special embedded application. But all other users can use this skelet for other LC displays without memory mapped video ram. Such a graphic LCD on LPT port. In this case, I hope you will not delete the monochrome LOGO in your new logo code!

In 2.2.19, the console subsystem disables interrupts when outputting to the
console. This was fixed in 2.4.x.

Hi James,
Although fbcon can be compiled as a module, it cannot be safely unloaded
yet. If fbcon is unloaded, it typically results in a frozen box.
Allowing fbcon to successfully unload may be not so useful with typical
usage, but will be very helpful for developers. So here's a preliminary
patch to allow unloading of fbcon.
The main logic of the patch is when a console driver calls
take_over_console(), 'conswitchp' will be saved to 'defcsw'. When it
calls give_up_console() later on, aside from just unmapping the console
driver (which is what the original code does), it will also attempt to
reinstall the default console using the saved 'defcsw'pointer.
To minimize complexity, only one driver will be allowed to 'take over'
the console at a time. Succeeding calls to take_over_console() will
fail unless the driver gives up the console.
I made this a kernel config option, marked DANGEROUS. Also, only drivers
with an info->fbops->fb_release() hook will be allowed to unload. The
fb_release() hook need not do anything. Currently, fbcon on top of
vga16fb, rivafb or i810fb can be unloaded. I have tested this using
dummycon and vgacon.
Upon unload, the restored console will be partially corrupted. Also, I
think unicode mapped characters are not fully restored.
Any comments welcome.
Tony

BTW, most of the logo drawing is still not protected by CONFIG_(FB_)_LOGO. This
needs to change before it's submitted to Linus.
And why is the logo drawn from fbcon_switch() (which is not __init)? Does this
also explain why it's drawn twice (at least on some fbdevs)?

Unless we ever want to support colors > 256 (or real pixel values)?
Alternatively, we can split imageblit in two routines, one for image drawing,
and one for color expansion.
So we now have 3 options:
1. image.depth = 0 means color expansion,
2. fb_image.{bg_color,fg_color} = -1 means color expansion,
3. separate functions for image drawing and color expansion.
I still favor solution 1, since image.depth = 0 is not possible for images,
while fb_image.{bg_color,fg_color} = -1 (= 0xffffffff) may become valid in the
future, and the last one is more work to adapt the current drivers.

FROM:WILLIAMS MAKO Good day, You may be surprised to receive this letter from me since you do not know me personally. The purpose of my introduction is that I am williams mako, the first son of Zuma mako one of the most popular black farmer in Zimbabwe who was recently murdered in the land dispute in my country. I got your contact through network online hence decided to write you. Before the death of my father, he had taken me to Johannesburg to deposit the sum of USD$14.5 million (Fourteen million, Five Hundred thousand United Statesdollars), in one of the private security company, as he foresaw the looming danger in Zimbabwe this money was deposited in a box as gem stones to avoid much demurrage from security company. This amount was meant for the purchase of new machines and chemicals for the Farms and establishment of new farms in swaziland. This land problem came when Zimbabwean President Mr. Robert Mugabe introduced a new Land Act Reform wholly affecting the rich white farmers and some few black farmers, and this resulted to the killing and mob action by Zimbabwean war veterans and some lunatics in the society. In fact a lot of people were killed because of this Land reform Act for which my father was one of the victims. It is against this background that, I and my family fled Zimbabwe for fear of our lives and are currently staying in the Netherlands where we are seeking political asylum and moreso have decided to transfer my fathers money to a more reliable foreign account. since the law of Netherlands prohibits a refugee (asylum seeker) to open any bank account or to be involved in any financial transaction throughout the territorial zone of Netherlands, As the eldest son of my father, I am saddled with the responsibility of seeking a genuine foreign account where this money could be transferred without the knowledge of my government who are bent on taking everything we have got. The South African government seems to be playing along with them. I am faced with the dilemma of moving this amount of money out of South Africa for fear of going through the same experience in future, both countries have similar political history. As a businessman,I am seeking for a partner who I have to entrust my future and that of my family in his hands, I must let you know that this transaction is risk free. If you accept to assist me and my family, all I want you to do for me, is to make an arrangements with the security company to clear the consignment(funds) from their affiliate office here in the Netherlands as i have already given directives for the consignment to be brought to the Netherlands from South Africa.But before then all modalities will have to be put in place like change of ownership to the consignment and more importantly this money I intend to use for investment. I have two options for you. Firstly you can choose to have certain percentage of the money for nominating your account for this transaction. Or you can go into partnership with me for the proper profitable investment of the money in your country. Whichever the option you want, feel free to notify me. I have also mapped out 5% of this money for all kinds of expenses incurred in the process of this transaction.If you do not prefer a partnership I am willing to give you 10% of the money while the remaining 85% will be for my investment in your country. Contact me with the above E-mail addresse,while I implore you to maintain the absolute secrecy required in this transaction. Thanks, GOD BLESS Yours Faithfully, Mr williams mako |

How do I ensure that such parameters as the refresh rate, hsync width and
offset, vsync width and offset are too my liking?
I've noticed that there seems to be some variation between the parameters
used, and I'd prefer to use my set since they match the host OS (it means
I don't have to keep readjusting the screen each time I change OS.)

How about assigning fb_image.{bg_color,fg_color} to -1 if not color
expanding? Since the pseudo_palette will not exceed 255, this should be
safe.

In order to do this, fb_imageblit has to support transparency (using a
transparency bitmask). Userland apps will rarely have rectangular mouse
cursor pointers. Also, it will need to support ROP's invert and copy.
This will break fb_imageblit.
Also, we have to double-buffer what's underneath the cursor.

However, I won't be able to manage the BK repository since I don't have broadband access (cannot recover from a failed bk clone). It's best if you leave this to someone who can. I'll be of better help if we can populate the CVS repository in sourceforge? Tony |
