09:02 < wsa> again, welcome everyone. IO meeting time now 09:02 < wsa> status updates: 09:02 < wsa> Status updates 09:02 < wsa> ============== 09:02 < wsa> A - what have I done since last time 09:02 < wsa> ------------------------------------ 09:02 < wsa> Kaneko-san 09:02 < wsa> : upported I2C, SCIF, HSICF enablement for E3 09:02 < wsa> Marek 09:02 < wsa> : upported SCIF2 pinmux patches, SDHI patches for E3 and submitted V2 for 09:02 < wsa> the PCIe L1 ATF workaround 09:02 < wsa> Niklas 09:02 < wsa> : (did various SDHI patches to enable HS400 but missed to send in his report) 09:02 < wsa> Shimoda-san 09:02 < wsa> : fixed remove function of SCIF driver and investigated an issue for USB3.0 09:02 < wsa> peripheral with E3 09:02 < wsa> Ulrich 09:02 < wsa> : reviewed two SCIF patches 09:02 < wsa> Wolfram 09:02 < wsa> : organied and participted in SDHI hackfest, imported periupport priorities to 09:02 < wsa> latest ticket file, picked up TDSEL and WDT patches again, reviewed lots of 09:02 < wsa> SDHI patches and some general PM rework, updated periupport, and started to 09:02 < wsa> pick up I2C core PM rework again 09:02 < wsa> B - what I want to do until next time 09:02 < wsa> ------------------------------------- 09:02 < wsa> Geert 09:02 < wsa> : wants to resubmit fixes for fallback to PIO in the sh-sci driver 09:02 < wsa> Kaneko-san 09:02 < wsa> : wants to upport HSCIF, PWM, and PCIE for E3 09:02 < wsa> Marek 09:02 < wsa> : wants to continue on PCI, DVFS I2C and PMIC upporting for E3 and PCA953x 09:02 < wsa> suspend/resume support 09:02 < wsa> Shimoda-san 09:02 < wsa> : wants to fix the USB3.0 issue for E3 and investigate a USB related reset 09:02 < wsa> issue for Gen2 09:02 < wsa> Simon 09:02 < wsa> : wants to investigate RAVB no-link patches in BSP 3.7.2 09:02 < wsa> Ulrich 09:02 < wsa> : wants to continue reviewing patches 09:02 < wsa> Wolfram 09:02 < wsa> : wants to continue I2C core PM rework and upport BSP patches 09:02 < Marex> wsa: clock 09:03 < wsa> C - problems I currently have 09:03 < wsa> ----------------------------- 09:03 < wsa> Shimoda-san: 09:03 < wsa> asks for documentation introducing to virtualization 09:03 < wsa> Simon: 09:03 < wsa> has D3 thermal support tested but patches stuck on upstream mailing list 09:03 < wsa> my questions: 09:04 < wsa> horms: I assume the IIC issue with ICSTART are resolved now? 09:04 < wsa> horms: any plan when you can start working on the RAVB no-link patches? 09:05 < wsa> Marex: did you coordinate your E3 upporting work with someone? I mean it is great to see progress there, but there is work assigned to Kaneko-san already and I'd like to avoid duplication of work... 09:06 < Marex> wsa: I checked with geertu, he said it was OK 09:06 < Marex> wsa: I was concerned about Kaneko-san, yes 09:07 < Marex> wsa: is the PCI/I2C/PMIC task assigned ? 09:08 < wsa> Marex: Good, thanks! I will check with geertu then how to handle this in the future... 09:08 < wsa> PCIE and IIC is, PMIC not 09:08 < geertu> Marex: i2c was not mentioned in last's IO meeting report, PMIC was for core 09:09 < wsa> It probably makes sense to combine IIC and PMIC 09:09 < wsa> to you 09:09 < geertu> I've been running with iic and pmic enabled on e3 09:09 < wsa> It is a grey area, I think, because PFC is core and I2C itself is IO 09:09 < geertu> iic works 09:10 < geertu> pmic is blocked by Ebisu firmware not supporting s2ram on the 4D variant yet 09:10 < geertu> Else I would have had submitted it myself the week I got the board. 09:10 < wsa> so, not much harm done (I think), but a sign to install some communication between geert and me here 09:12 < wsa> I also think it would make sense to assign PCIE to Marex but we also need work for Kaneko-san 09:12 < wsa> I will check this when I update the lists after the meeting 09:12 < wsa> horms: is this all OK with you? 09:12 < Marex> wsa: OK 09:12 < geertu> Can Kaneko-san test his work on some board now? 09:12 < geertu> Apparently his last PFC patch was not even compile-tested 09:12 < Marex> wsa: I tested the PCIe on Ebisu 4D already 09:13 < Marex> wsa: so I can roll out the patch right away 09:13 < wsa> neg: you there? 09:13 < wsa> Marex: heh 09:15 < wsa> I also wonder about Jinso sending thermal patches... 09:16 < wsa> why exactly this driver? :) 09:16 < wsa> damm: do you know about this? 09:16 < damm> nope sorry 09:17 < wsa> pity neg seems not here, too 09:17 < wsa> neither he sent a report, I hope he is well 09:17 < Marex> wsa: probably on his way to Canada ? 09:17 < Marex> wsa: so anyway, I'll wait with the PCIe patches ? 09:18 < geertu> He said his mail and git trees will be cut off for a week by its hosting provider, perhaps that has already started, and caused more damage than expected? 09:18 < wsa> Marex: yes, but probably just until this evening 09:18 < wsa> just until I updated all my lists 09:18 < Marex> wsa: got it, will do 09:19 < wsa> Marex: thanks 09:20 < wsa> so, the updated periupport list with imported priorities... 09:20 < wsa> morimoto: are you okay with this (in general)? 09:20 < wsa> geertu: did you have a chance to look at it? 09:20 * morimoto talking with our Boss now 09:21 < wsa> I would be nice to merge it rather soonish, I'd think. pinchartl and my updates are already depending on it... 09:22 < wsa> pinchartl: thanks for the prompt review! 09:22 < geertu> wsa: I only had a brief look. 09:23 < wsa> Marex: did the HS400 clock fix from this night also fix the HS400 issue in Linux then? 09:23 < geertu> I did do some auto-updates and fixed obsolete linux-next references 09:23 < wsa> geertu: before or after the conversion? 09:24 < Marex> wsa: no, I'm still seeing that and I'm not sure why 09:24 < Marex> wsa: I have a hypothesis, but I need to test it 09:24 < geertu> wsa: on master 09:25 < wsa> Marex: which hypothesis? 09:25 < morimoto> wsa: basically I have no objection (= for periupport) 09:25 < Marex> wsa: that it has to do somehow with the board physical properties, possibly temperature 09:25 < wsa> Marex: there are HS400 related patches in the latest BSP dealing with temperature 09:26 < Marex> wsa: I have very little samples to support the hypothesis, but the HS400 worked in Linux if I cold started the board after some idle period 09:26 < Marex> wsa: on the next reboot or power cycle, it failed 09:26 < Marex> wsa: even if I waited a bit to discharge the caps 09:27 < Marex> thus, I suspect temperature, but like I said, I have very little samples to support this 09:27 < Marex> I need to test more 09:27 < wsa> 09:27 < wsa> Since Gen3 SDHI has a internal DS signal AC-spec violation in HS400 mode, 09:27 < wsa> CRC-error may occur in read command. It is only HS400 mode. 09:27 < wsa> This phoenomenon occurs at low/High temperature. 09:27 * wsa wonders about Marex room temperature ;) 09:29 < wsa> geertu: do you want to have time for another look at the periupport changes? 09:30 < Marex> wsa: I saw that patch 09:30 < Marex> wsa: I rather wonder if this has to do with the CPU heating up the board, or itself 09:30 < wsa> Marex: sure, was j/k 09:30 < geertu> wsa: I'll have a closer look 09:31 < geertu> (using the pre-commit hook or make patch ;-) 09:31 < Marex> wsa: I suspect that violation is also present on older Gen3s and that results in the 4TAP 400MHz SDnH limitation ? 09:31 < wsa> geertu: ok, let me know what you think by mail then. Thanks! 09:32 < Marex> wsa: but then I wonder if on 4tap SoCs, the performance in the HS400 mode is worse than on 8tap SoC ... 09:33 < wsa> Marex: my gut feeling is there is some bigger thing going wrong, but it's all speculation 09:33 < wsa> and not terribly important why exactly there are 4 taps 09:33 < Marex> wsa: the thing is, when I configured the clock correctly for the 8tap/HS400, the raw read performance almost doubled ... 09:34 < Marex> wsa: so I wonder if on 4tap SoCs, the read performance in HS400 would be lower than on 8tap SoC 09:34 < wsa> Marex: I expect the 4tap performance to be worse than 8tap 09:34 < wsa> but as long as it is > HS200... 09:35 < Marex> wsa: it was exactly equal for me 09:35 < Marex> wsa: but I need to revisit the 4tap case 09:35 < wsa> AFAICS there is not much we can do, and the focus should be the latest ES version anyhow 09:36 < wsa> neg did a chart 09:36 < Marex> wsa: right, the scratchpad 09:36 < geertu> Who has access to H3 ES3.0? 09:37 < Marex> geertu: I had it in my hands once 09:37 < wsa> neg had a slight increase on H3 ES2.0. that matches my experiences 09:37 * wsa notes to update the chart with his results 09:38 < wsa> okay, are there questions from your side 09:38 < wsa> ? 09:39 < wsa> sadly, no responses from horms about questions to him. Simon, if you read this later, please respond by mail to periperi 09:39 < Marex> wsa: on H3, I had 170MB/s in both HS200 and HS400, so no increase for me :( 09:40 < Marex> wsa: but I suspect 200 MB/s might be the limit for 4tap configs 09:40 < wsa> let's update the table and continue the discussion by mail, too 09:40 < Marex> wsa: sounds good 09:40 < wsa> Marex: thanks! 09:41 < wsa> let's get to the core now :) 09:41 < wsa> geertu: have fun! ='#n190'>190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 302 303 304 305 306 307 308 309 310 311 312 313 314 315 316 317 318 319 320 321 322 323 324 325 326 327 328 329 330 331 332 333 334 335 336 337 338 339 340 341 342 343 344 345 346 347 348 349 350 351 352 353 354 355 356 357 358 359 360 361 362 363 364 365 366 367 368 369 370 371 372 373 374 375 376 377 378 379 380 381 382 383 384 385 386 387 388 389 390 391 392 393 394 395 396 397 398 399 400 401 402 403 404 405 406 407 408 409 410 411 412 413 414 415 416 417 418 419 420 421 422 423 424 425 426 427 428 429 430 431 432 433 434 435 436 437 438 439 440 441 442 443 444 445 446 447 448 449 450 451 452 453 454 455 456 457 458 459 460 461 462 463 464 465 466 467 468 469 470 471 472 473 474 475 476 477 478 479 480 481 482 483 484 485 486 487 488 489 490 491 492 493 494 495 496 497 498 499 500 501 502 503 504 505 506 507 508 509 510 511 512 513 514 515 516 517 518 519 520 521 522 523 524 525 526 527 528 529 530 531 532 533 534 535 536 537 538 539 540 541 542 543 544 545 546 547 548 549 550 551 552 553 554 555 556 557 558 559 560 561 562 563 564 565 566 567 568 569 570 571 572 573 574 575 576 577 578 579 580 581 582 583 584 585 586 587 588 589 590 591 592 593 594 595 596 597 598 599 600 601 602 603 604 605
