Closed spasswolf closed 3 months ago
it seems I cannot fork torvalds/linux, because I already have forked msm8953-mainline/linux (which is itself a fork of msm8916-mainline/linux which is a fork of torvalds linux).
git remote add torvalds https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git git fetch torvalds master git checkout torvalds/master
Thanks, I created the patches above by remote adding my github fork to my local clone of linux-next so it's strange that I didn't think of this.
Done. In my github repository https://github.com/spasswolf/linux.git there's now a branch with the clunky name msm8953_iommu_gpu_wlan_modem_ipa which contains the patches above, rebased to linux-next-20230621 (everything still working).
Edit: Kernel .config: msm8953_config.txt
成交。在我的github存储库中https://github.com/spasswolf/linux.git现在有一个名为msm8953_iommu_gpu_wlan_modem_ipa的分支,它包含上面的补丁,重新基于linux-next-20230621(一切都正常工作)。
编辑:kernel. Config:msm8953_config.txt
你好!这个分支modem可以正常工作了吗?
I have not yet tried mobile data but SMS is working and calls would probably work but the fairphone-fp3 has no working audio, yet.
On the bright side, this little patch (not yet pushed) gives torch led support for the fairphone-fp3 using the qcom,spmi-flash-led driver:

So far I've only set led brightness in sysfs, e.g.
echo 10 > /sys/class/leds/yellow\:flash/brightness
echo 0 > /sys/class/leds/yellow\:flash/brightness
echo 10 > /sys/class/leds/white\:flash/brightness
echo 0 > /sys/class/leds/white\:flash/brightness
Is there a standard tool to do this from gnome?

@spasswolf Interesting that flash works for you, would've expected more code to be needed that's present downstream. From my notes:
Big picture changes: driver sets POWER_SUPPLY_PROP_FLASH_ACTIVE on power supply, uses power supply for turning on power, then waits until power is on and then does the normal stuff. max-channels=2
"PMI632 flash is driven by the charger in reverse boost (bharger) mode instead of the BoB regulator." (commit 1c1e21ca0c149a9eda3004c84378f92bee4a7ed7)
"flash LED subtype 0x5"
Maybe it just works because we don't have smb5 charger support yet and bootloader has this power rail enabled?
I just noticed that suspend (on fairphone-fp3) is working with this kernel, supend can be initiated either by pressing the power button or by selecting suspend in the gnome menu. Wakeup is a little tricky though, sometimes pressing the power button is enough but that only seems to work while the phone is connected via usb. Also sometime resuming with the power button does not work, but disconnecting and reconnecting the usb cable wakes up the phone.
Even in the case of a succesful suspend the modem cannot be found but this is easily fixed by
service ModemManager restart
Edit: dmesg messages while supending/resuming

Edit2: If I try to resume by pressing the power button, and the phone is not connected via usb this leads to rebooting the phone.
Edit3: Supend with linux-msm8953, branch 6.3.0/ipa_test_v3 seems to work better even without attached usb cable, but the ModemManager restart issue is present here, too.
Edit4: It seems as if the usb30 clk error is causing the suspend problems, I've cherry-picked cpufreq and cpuidle patches but still wakeup from suspend takes a long time. (code is in msm8953_iommu_rebase_v2_wlan_modem_ipa_cpufreq branch, rebased to linux-next-20230630)
Cherry-picking this commit has improved the resume speed, but the gcc_usb30_master_clk status stuck at 'on'
is still there.

soc: qcom: rpmpd: add hack to speed up suspend/resume
commit 0df07fc605ffc3ab30b597de992711f5e9a
Suspending (by pressing the power button) and immediately resuming (by pressing the power button again) leads to a slow resume and lots (thousands) of touchscreen errors:

This problem seems to occur for linux-6.3, too.
Added a simple workaround to reduce log spamming:

@spasswolf I think this touchscreen issue will ultimately be resolved with https://lore.kernel.org/linux-arm-msm/20230607215224.2067679-1-dianders@chromium.org/ (+ some extra patches for this touch driver)
I've tried to integrate display following into the himax_hx83112b touchscreen driver, the first version is in branch msm8953_iommu_rebase_v2_wlan_modem_ipa_cpufreq in https://github.com/spasswolf/msm8953-linux.git.

This error (which is most likely unrelated to the panel following, as it was present in the old version, too)

is caused by dsi_host_transfer, because msm_host->power_on is 0:
static ssize_t dsi_host_transfer(struct mipi_dsi_host *host,
const struct mipi_dsi_msg *msg)
{
struct msm_dsi_host *msm_host = to_msm_dsi_host(host);

if (!msg || !msm_host->power_on) {
printk(KERN_INFO "%s %d: msg = %px, msm_host->power_on = %d\n", __func__, __LINE__, msg, msm_host->power_on);
return -EINVAL;
}
mutex_lock(&msm_host->cmd_mutex);
ret = msm_dsi_manager_cmd_xfer(msm_host->id, msg);
mutex_unlock(&msm_host->cmd_mutex);

}
gives

Edit: This seems to be related to a similar issue encountered when switching on the display https://github.com/msm8953-mainline/linux/issues/55#issuecomment-1578522875, here too functions were called in the wrong order.
This works around both problems (the display init and the display suspend):

Yes. Every panel needs it.
Done and force-pushed to msm8953_v6.4_gpu_wlan_modem_ipa_cpufreq branch, so that all the fixes are in one commit.
Hi @spasswolf couple of stuff was upstreamed: GPU, iommu stuffs. I think it can be closed because these are outdated patches now.
This is a collection of the patches for msm8953 support in linux-next (currently for linux-next-20230616, but rebasing them to newer version was without problems so far, I started at linux-next-20230609). It would be nicer if I could just push them to a tree, but unfortunately it seems I cannot fork torvalds/linux, because I already have forked msm8953-mainline/linux (which is itself a fork of msm8916-mainline/linux which is a fork of torvalds linux).
