Cosa diavolo è mesa-amber

Provato a rimuovere l'hook kms da mkinitcpio.conf, nessun effetto

Ora provo a
• installare mesa-amber (va in conflitto con mesa)
• impostare
__GLX_VENDOR_LIBRARY_NAME=amber
• rigenerare l'initcpio

Nada

A quanto pare in /sys/class/backlight è sparito tutto,
prima c'era acpi_video0
e intel_backlight

Questo mi ha fatto intuire una cosa

Ho fatto il downgrade del kernel ed ha funzionato 🥲

6.0.11 <- 6.1.6

Non male

Mi ero completamente scordato che i pacchetti AUR sono sotto git (e quindi eventualmente downgrade-abili)

Alcuni estratti

To get those labels, OpenAI sent tens of thousands of snippets of text to an outsourcing firm in Kenya, beginning in November 2021. Much of that text appeared to have been pulled from the darkest recesses of the internet. Some of it described situations in graphic detail like child sexual abuse, bestiality, murder, suicide, torture, self harm, and incest.

One Sama worker tasked with reading and labeling text for OpenAI told TIME he suffered from recurring visions after reading a graphic denoscription of a man having sex with a dog in the presence of a young child. “That was torture,” he said. “You will read a number of statements like that all through the week. By the time it gets to Friday, you are disturbed from thinking through that picture.” The work’s traumatic nature eventually led Sama to cancel all its work for OpenAI in February 2022, eight months earlier than planned.

In February, according to one billing document reviewed by TIME, Sama delivered OpenAI a sample batch of 1,400 images. Some of those images were categorized as “C4”—OpenAI’s internal label denoting child sexual abuse—according to the document. Also included in the batch were “C3” images (including bestiality, rape, and sexual slavery,) and “V3” images depicting graphic detail of death, violence or serious physical injury, according to the billing document. OpenAI paid Sama a total of $787.50 for collecting the images, the document shows.

But the need for humans to label data for AI systems remains, at least for now. “They’re impressive, but ChatGPT and other generative models are not magic – they rely on massive supply chains of human labor and scraped data, much of which is unattributed and used without consent,” Andrew Strait, an AI ethicist, recently wrote on Twitter. “These are serious, foundational problems that I do not see OpenAI addressing.”

Vsync experiments

Devo preoccuparmi??

Nuove osservazioni

Con il seguente setup:
• driver intel su xorg
(niente modesetting)
• kernel mode setting attivo
(è una cosa diversa)
• accelerazione SNA
• opzione TearFree attiva
• nessun compositor

= le applicazioni opengl soffrono di gravi cali ogni ~3s di durata ~½s

Se in aggiunta viene forzata l'opzione lato MESA vblank_mode=3, questo problema scompare


Usando intel + l'accelerazione UXA, firefox non avrà mai vsync, nonostante tutte le altre opzioni.

                                                               
Usando modesetting non c'è vsync di default, e aggiungendo SNA (il default è glamor) và in software raster

                                                               
Utilità
export LIBGL_DEBUG=verbose
less /var/log/Xorg.0.log

My firefox experience

Il video è a 60fps per evidenziare i brevi stutter nonostante il vsync

Solo firefox ha questo problema
