Since the previously version posted some months ago, I fixed up a number of bugs. I also added support for a range of other Realtek based USB devices. The driver now supports rtl8723au, rtl8188cu, rtl8188ru, and rtl8192cu. It should work on rtl8191cu devices as well. Per default only devices I have actually tested will be enabled. If you are interested in trying it out with other 8188cu/8188ru/819[12]cu dongles, you need to enable CONFIG_RTL8XXXU_UNTESTED. Please report test results back to me. Note if you enable this driver, it may clash with CONFIG_RTL8192U, CONFIG_R8723AU, and CONFIG_RTL8192CU (rtlwifi). Please pay attention to which module you load and/or use modprobe blacklists. This driver is still work in progress. I have used it as my primary driver for the last six months, and I find it to be very stable. It seems suitable for mainline inclusion at this point.

It was written from scratch utilizing the Linux mac80211 stack. After spending months cleaning up the vendor provided rtl8723au driver, which comes with it's own 802.11 stack included, I decided to rewrite this driver from the bottom up. Many thanks to Johannes Berg for 802.11 insights and help and Larry Finger for help with the vendor driver. The full git log for the development of this driver can be found here: git git://git.kernel.org/pub/scm/linux/kernel/git/jes/linux.git branch rtl8723au-mac80211 This driver is still under development, but has proven to be very stable for me. It currently supports station mode only. It has support for OFDM and CCK rates, as well as AMPDU. It does lack certain features found in the staging driver, such as power management and 40MHz channel support. In addition it does not support AD-HOC, AP, and monitor mode support at this point. The driver is known to work with the following devices: Lenovo Yoga (rtl8723au) TP-Link TL-WN823N (rtl8192cu) Etekcity 6R (rtl8188cu) Daffodil LAN03 (rtl8188cu) Alfa AWUS036NHR (rtl8188ru) Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> --- MAINTAINERS | 7 + drivers/net/wireless/Kconfig | 32 + drivers/net/wireless/Makefile | 2 + drivers/net/wireless/rtl8xxxu.c | 5829 ++++++++++++++++++++++++++++++++++ drivers/net/wireless/rtl8xxxu.h | 597 ++++ drivers/net/wireless/rtl8xxxu_regs.h | 980 ++++++ 6 files changed, 7447 insertions(+) create mode 100644 drivers/net/wireless/rtl8xxxu.c create mode 100644 drivers/net/wireless/rtl8xxxu.h create mode 100644 drivers/net/wireless/rtl8xxxu_regs.h diff --git a/MAINTAINERS b/MAINTAINERS index b60e2b2..54b03bd 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -8699,6 +8699,13 @@ S: Maintained F: drivers/net/wireless/rtlwifi/ F: drivers/net/wireless/rtlwifi/rtl8192ce/ +RTL8XXXU WIRELESS DRIVER (rtl8xxxu) +M: Jes Sorensen <Jes.Sorensen@redhat.com> +L: linux-wireless@vger.kernel.org +T: git git://git.kernel.org/pub/scm/linux/kernel/git/jes/linux.git rtl8723au-mac80211 +S: Maintained +F: drivers/net/wireless/rtl8xxxu*.[ch] + S3 SAVAGE FRAMEBUFFER DRIVER M: Antonino Daplas <adaplas@gmail.com> L: linux-fbdev@vger.kernel.org diff --git a/drivers/net/wireless/Kconfig b/drivers/net/wireless/Kconfig index a63ab2e..def6cfd 100644 --- a/drivers/net/wireless/Kconfig +++ b/drivers/net/wireless/Kconfig @@ -243,6 +243,38 @@ config ADM8211 Thanks to Infineon-ADMtek for their support of this driver. +config RTL8XXXU + tristate "RTL8723AU/RTL8188[CR]U/RTL819[12]CU (mac80211) support" + depends on MAC80211 && USB + ---help--- + This is an alternative driver for various Realtek RTL8XXX + parts written to utilize the Linux mac80211 stack. + The driver is known to work with a number of RTL8723AU, + RL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU devices + + This driver is under development and has a limited feature + set.

A comment would suffice, but the question is really whether it adds value to the code doing so - since 99.99% of users will never see this compiler warning.

Interesting, I am trying to use the settings coming out of the efuse, but it is not impossible I do something wrong with them.

OK, I get a bit better than the top G rate of 27 Mbps, but the connection reports a 54 Mbps raw rate. My Intel 7260 gets RX of 95 and TX of 53 Mbps from the same location relative to the AP. For the Intel, the listed raw rate is 300 Mbps. >>>>> I don't think any of this is showstopper material for inclusion right >>>>> now, albeit I do want to address them. >>>> >>>> The scheduling while atomic problems do need to be fixed, and I am >>>> still working on the failure to get a wifi device on PPC. >>> >>> It's already fixed :) >> >> A full debug=0x3fff showed me one problem on the PPC.

Today I know that is not a lock dependency issue. I have one in VirtualBox that fires and disables further checking, but that driver is not loading now. I have made some progress on the big-endian issues. When the firmware file is read from disk, the first byte read must be the first byte written to the device. In the slow write N routine, four bytes are picked and written using the write32 routine, which does a cpu_to_32() byte swap. As a result, the order of bytes to the device is 03, 02, 01, 00! Rather than byte swap twice, I am calling the regular writeN routine with each hunk. After a bit of thinking about the best blocksize to use, I settled on 64. That reduces the number of full-size hunks that are written without unduly increasing the worst-case number of writes needed for the remainder. On PPC, I now get a device registered; however, the scan data are garbled. That shouldn't be too difficult to debug, but just in case, I have attached the patch for rtl8xxxu_slow_writeN().

It's possible the connection reporting I am doing is wrong. I haven't figured out how to report the actual transmission speed, which is what the mac80211 stack wants. Some of the other drivers fake it or repor RX speeds, but that isn't what one is meant to report. >>> A full debug=0x3fff showed me one problem on the PPC.

As I mentioned in a direct email - calling writeN from slow_writeN is not a solution. I found some devices fail if you try to use the fast writeN routine. Maybe rtl8xxxu_raw_write32() - without the byteswap would be a better approach, or simply putting the relevant code into the slow_writeN function. I am flying back to New York tomorrow, and I'll have some time on the plane, so I'll try to have a look at that. Cheers, Jes ^ permalink raw reply [flat|nested] 44+ messages in thread

I will add the USB calls to slow_writeN. I see, it's possible we need to add it as a parameter to writeN or add the size to the fops struct for the different device types. In fact the latter might be a cleaner approach, especially if it works for 8192/8188 devices with 64 byte writes. Getting rid of slow_writeN altogether would be nice.

The chip has antennas and internal paths or streams and if I understand it right, granted not having any specs whatsoever, I may have gotten some of it wrong, you can wire path B to antenna A and vice versa.

I started working on this, but I guess I didn't finish it. One thing I haven't figured out yet is why I see AMPDU_RX_START events, but I never see AMPDU_TX_START events show in the log. >> sta_priv->short_preamble = false; > > I don't think there's any need to track it, especially since you only > use it in TX where you have the TX info data about it.

I added it because I was looking at using it for AMPDU, then got stock, but didn't feel like removing it in case I would need it later. I need to figure out what goes on with the AMPDU side of things - the problem writing a driver like this without any spec sheets is that it isn't quite clear to me, how much of this the firmware takes care of transparently. >> static void rtl8xxxu_sw_scan_start(struct ieee80211_hw *hw, >> struct ieee80211_vif *vif, const u8 *mac) >> { >> } > > No need for this ...

I went back and looked at this, and now I remember why I wrote the code the way I did. The Realtek firmware handles rate control, so once I set IEEE80211_HW_HAS_RATE_CONTROL, I never see rate_flags & IEEE80211_TX_RC_USE_SHORT_PREAMBLE nor tx_info->control_short_preamble.

Yes, this is a good point, and the preamble can't really be different for different stations since all the stations in the BSS (and even outside it on the same channel) must be able to decode it.

Gotcha, now you mention it, that rings a bell! I'll put that on my todo list. One of the biggest things puzzling me is how much the firmware does with AMPDU - there is a break bit I can set in the TX descriptor to say 'don't AMPDU this packet' but do not actually know if it will do all of this behind my back.

In the long term, do you plan for this driver to support the RTL8188EU-based devices as well? I've been checking how far I can get through the rtl8xxxu initialization using a TP-Link TL-WN725N dongle without changing too much. Getting it up to read the EFUSE contents wasn't difficult but then you need to parse it and first differences come to light. Namely, TX power levels are defined per each of 6 (not 3) channel groups, and power differences are defined per TX path (as opposed to per channel group). This is perhaps better described by the relevant structure from rtl8188eu driver: struct txpowerinfo24g { u8 IndexCCK_Base[MAX_RF_PATH][MAX_CHNL_GROUP_24G]; u8 IndexBW40_Base[MAX_RF_PATH][MAX_CHNL_GROUP_24G]; /* If only one tx, only BW20 and OFDM are used. */ s8 CCK_Diff[MAX_RF_PATH][MAX_TX_COUNT]; s8 OFDM_Diff[MAX_RF_PATH][MAX_TX_COUNT]; s8 BW20_Diff[MAX_RF_PATH][MAX_TX_COUNT]; s8 BW40_Diff[MAX_RF_PATH][MAX_TX_COUNT]; }; AFAICT, in this regard, rtl8188eu driver has more in common with the rtlwifi/rtl8188ee driver. I'm curious what is your opinion on this. In particular, do you see any reason not to make an attempt to extend rtl8xxxu to support 8188EU chips?

It can be deducted from the vendor driver code. The layout pretty much differ for each chip, but I have seen enough of them by now that I can parse most of it by looking at the hex dump. I think the 8188EU uses IOL, which is an enhanced firmware assist API. That will change the programming a bit, but I think it's well within scope for this driver to support this as well. In other words, it is my plan to look at the 8188EU. If you get it going before me, I am very happy to work with you on integrating the patches.

If you get it going > before me, I am very happy to work with you on integrating the patches. Jakub, Digging a bit further, it looks like the 8188EU, 8192EU, and 8723BU, use a different RF module than the previous parts. They have far more RF registers, so the code for reading/writing RF registers does not work as is. Hopefully shouldn't be too hard to fix, but it also mean that the RF init table used for the older parts will not match whats needed for the new parts.

The performance is a lot better than I said in my previous post. Measuring with netperf for 3 second intervals, I get a maximum RX rate of 33.0 Mbps and a long-term average (750 samples) of 20.8 Mbps. For TX, the max is 34.5 Mbps and the average is 27.4.

Larry, Just to be sure I got it right, you're saying the gain issue is not an issue with this version of the code after all?
