|---|---|---|
| mntmn | yep | 14:03 |
| mntmn | unfortunately they still didn't announce any bigger imx9 | 14:04 |
| mntmn | only the i.MX 93 | 14:04 |
| dj-death | yeah | 14:04 |
| dj-death | but without GPU | 14:05 |
| mntmn | well, 2D ;) | 14:05 |
| mntmn | i mean, could be an interesting low power chip | 14:05 |
| mntmn | also, flexio | 14:05 |

| dj-death | lacks of proper 3D is sad | 14:06 |
| mntmn | but also no pcie, usb3. | 14:07 |
| mntmn | i am sure there are bigger imx9s but still under wraps | 14:08 |

| ndufresne | or they finally opted for iommus and are struggling getting them to work ;-D | 15:19 |
| ndufresne | for the reform laptop, iommus on GPU and VPU would make it for much snappier user experience for sure | 15:20 |
| mntmn | ndufresne: can you explain why that would be? | 15:24 |
| ndufresne | mntmn: whenever you start a GL/Vulkan or CODEC payload, the process will have to allocate memory, with iommus, this nearly as fast as doing malloc(), while with without iommu (like on all NXP chips), the CMA allocator is getting called | 15:25 |
| mntmn | interesting | 15:26 |
| ndufresne | The allocate have a non-deterministic allocation time, which will worsten over time due to fragmentation of the memory | 15:26 |
| mntmn | and how does the iommu solve that? | 15:26 |
| ndufresne | you don't have to move the pages to form a contiguous blob anymore | 15:27 |
| mntmn | ah, you can allocate anywhere and the iommu will map it? | 15:27 |
| ndufresne | that makes allocation time pretty deterministic, and improve load time | 15:27 |
| ndufresne | correct, it basically give a memory mapping to your devices (not just the CPU) | 15:27 |
| ndufresne | it probably cost a bit in power and/or something else I'm not aware of, but for random payload like laptop, you can often notice the difference | 15:28 |
| ndufresne | that's because we cannot predict what users will do next, so we can't preallocate everything ;-P | 15:29 |
| ndufresne | there is likely different class of these, e.g. not all of them will support virtual memory (page-fault -> lazy allocation) | 15:30 |
| mntmn | pretty interesting. thanks for explaining. | 15:30 |
| ndufresne | and might not be totally unified, think of Intel display driver, everything can have virtual memory, except the display driver as it could fall behind the scannout (you can't slow it down) | 15:31 |
| ndufresne | so even though you have have randomly positionned pages, the pages needs to be in RAM, and cache flushed | 15:32 |
| ndufresne | before you can use it for display | 15:33 |

| vagrantc | is there anything dangerous about using the system console uart while running off of battery on the mnt-reform2 ? | 21:00 |
| vagrantc | and is there a pin somewhere with a reference voltage? | 21:01 |
| vagrantc | j22 pin15? | 21:02 |
| mntmn | vagrantc: no, that's not a problem at all. usually you don't need a ref voltage if you use a standard usb uart adapter | 21:04 |
| mntmn | vagrantc: (it is 3v3) | 21:04 |
| mntmn | vagrantc: and yeah the "expansion" header has that somewhere | 21:04 |

| kfx | I think I finally figured out how to adapt to the keyboard: I ordered a ridged keycap (https://i.imgur.com/uTBKY9K.png) for the right shift key | 22:04 |
| mntmn | kfx: interesting! | 22:06 |
| mntmn | we recently got a few samples of black ones iirc | 22:07 |
| kfx | I learned the hard way that I use the right shift key the most, with my pinky finger, and I use the left half of that key :) | 22:07 |

| mntmn | oh i see, that's unfortunate | 22:09 |
| kfx | eventually I'll adapt, but for now this is a good training wheel | 22:10 |

| mntmn | just ooc are you left or right handed? | 22:12 |
