The plan is to merge all current patch_*hdmi.c into one. But this can be done later once after we get the working driver for the new Nvidia codecs. The new Nvidia HDMI codec is a bit tricky (which has 4 separate codec slots), so I'd like to get it working first. thanks, Takashi ^ permalink raw reply [flat|nested] 45+ messages in thread

OK, it makes sense to solve one problem at a time. Wei Ni, would you ensure these naming rules: - unmodified functions: keep the original function name hdmi_* (if the original function name is intelhdmi_*, rename it to hdmi_*) - modified function: rename function name to nvhdmi_* (if the original function name is hdmi_*, rename it to intel_hdmi_*) And do the same for data structures, enums, variables, etc. This hopefully will make it easier to do the future merge.

Here is the patch to merge common code in a simple way. This is compile tested only, need double check. What puzzled me is that Wei Ni reused the same dynamic parsing code, even though the Intel/Nvidia codecs have vastly different pin/cvt layouts.. Thanks, Fengguang --- hdmi - create patch_hdmi.c common hdmi code For now the patch_hdmi.c file is not a real codec patch, but simply included by patch_intelhdmi.c and patch_nvhdmi.c.

WeiNi, some more questions. - why change hdmi_channel_mapping[0x32][8] from [0x13] = { 0x00, 0x11, 0x26, 0x37, 0x43, 0x52, 0x64, 0x75 }, to [0x13] = { 0x00, 0x11, 0x32, 0x23, 0x64, 0x75, 0x46, 0x57 }, - why remove "u8 reserved[5]; /* PB6 - PB10 */" from struct hdmi_audio_infoframe? - why change static void hdmi_checksum_audio_infoframe(struct hdmi_audio_infoframe *ai) { u8 *bytes = (u8 *)ai; u8 sum = 0; int i; ai->checksum = 0; for (i = 0; i < sizeof(*ai); i++) sum += bytes[i]; ai->checksum = - sum; } to static void hdmi_checksum_audio_infoframe(struct hdmi_audio_infoframe *ai) { ai->checksum = 0; } Those are very dirty changes. Either the original code is correct, or they are wrong and should be changed as well. If you submit code like this now, we'll have to resolve conflicts and do pointless retests at the perceived future merge time. Would you stop hacking things around like that? I'd recommend to base your future work on top of the following patch. It's based on your previous patches. Note that I reverted the above 3 changes. If they are good changes, you can still submit standalone patches, and let's discuss and test them case by case. Thanks, Fengguang --- hdmi - create patch_hdmi.c for common hdmi code For now the patch_hdmi.c file is simply included by patch_intelhdmi.c and patch_nvhdmi.c, and does not represent a real codec.

WeiNi, some more questions. - why change hdmi_channel_mapping[0x32][8] from [0x13] = { 0x00, 0x11, 0x26, 0x37, 0x43, 0x52, 0x64, 0x75 }, to [0x13] = { 0x00, 0x11, 0x32, 0x23, 0x64, 0x75, 0x46, 0x57 }, - why remove "u8 reserved[5]; /* PB6 - PB10 */" from struct hdmi_audio_infoframe? - why change static void hdmi_checksum_audio_infoframe(struct hdmi_audio_infoframe *ai) { u8 *bytes = (u8 *)ai; u8 sum = 0; int i; ai->checksum = 0; for (i = 0; i < sizeof(*ai); i++) sum += bytes[i]; ai->checksum = - sum; } to static void hdmi_checksum_audio_infoframe(struct hdmi_audio_infoframe *ai) { ai->checksum = 0; } Those are very dirty changes. Either the original code is correct, or they are wrong and should be changed as well. If you submit code like this now, we'll have to resolve conflicts and do pointless retests at the perceived future merge time. Would you stop hacking things around like that? I'd recommend to base your future work on top of the following patch. It's based on your previous patches. Note that I reverted the above 3 changes. If they are good changes, you can still submit standalone patches, and let's discuss and test them case by case. Thanks, Fengguang --- hdmi - create patch_hdmi.c for common hdmi code For now the patch_hdmi.c file is simply included by patch_intelhdmi.c and patch_nvhdmi.c, and does not represent a real codec.

About AZX_MAX_CODECS, on our new chipset, the codec_mask=0x31, it means the codec connect on the slot0, slot4, slot5, and on some GT2xx, the codec will connect to slot6 or slot7, although these chip at most have 4 codecs. So I change the AZX_MAX_CODECS to 8 directly. In hda_intel.c, the azx_command_addr(), azx_response_addr(), and azx_codec_create() use the AZX_MAX_CODECS, if it set as 4, the driver will not detect the codecs which connect to slot4~7. 2. yes, it's better to merge the hdmi common codes. 3. About ELD, yes, we need to change the Makefile and Kconfig as well. Could you help me to change it.

Yeah, I understand it. But, as mentioned, changing this to *all* controller chips is dangerous. We have already a quirk for controller chips to set max codecs depending on the chip model. Right now, only teradici chip sets to 1. So, add "#define AZX_DEFAULT_CODECS 4", and use this value unless azx_max_codecs[] is defined. And, for the new controller chip supporting more than 4, it can has 8 in azx_max_codecs[]. Is it feasible? > 2. yes, it's better to merge the hdmi common codes. > 3.

Yeah, I understand it. But, as mentioned, changing this to *all* controller chips is dangerous. We have already a quirk for controller chips to set max codecs depending on the chip model. Right now, only teradici chip sets to 1. So, add "#define AZX_DEFAULT_CODECS 4", and use this value unless azx_max_codecs[] is defined.

However, I don't see "CONFIG_SND_PCM_XRUN_DEBUG" anywhere in the kernel config (both in menuconfig or .config). Also, in order to use the snapshot I had to disable ALSA in my kernel anyways. I did try to enable it just to see if that option would appear somewhere but it did not. I am using stable kernel 2.6.33 btw. I don't see how I can create /proc/asound/card1/pcm3p/xrun_debug!
